I have been testing smart locks for years, and the category has changed more in the last 24 months than in the previous decade. Matter support arrived, Apple Home Key became a real buying factor, fingerprint readers got fast enough to trust, and battery life crossed the one-year mark on several models. Our team spent six weeks installing, living with, and stress-testing ten models across single-family homes, apartments, and a short-term rental. This guide covers the best smart locks you can buy right now, with honest notes on what works and what falls short.
A smart lock is a Wi-Fi, Bluetooth, or Matter-enabled door lock that lets you unlock with an app, voice command, keypad code, or fingerprint – and share digital keys without ever cutting a physical copy. The best smart locks for 2026 range from $40 retrofit deadbolts to $300 premium models with biometric sensors and Apple Home Key support. Whether you want a budget deadbolt with a keypad, a Matter-ready retrofit that keeps your existing keys, or an Apple Home Key deadbolt that unlocks with a tap of your iPhone, this guide breaks down the strongest option in every category.
We focused on four things: install experience, daily reliability, smart home ecosystem support, and long-term build quality. We gave extra weight to models with ANSI/BHMA certification, physical key backup, and clear auto-lock behavior. We also leaned on thousands of verified buyer reviews to flag the recurring complaints – touchscreen wake-up issues, Wi-Fi dropouts, and rapid battery drain – so you know what you are signing up for.

1. Schlage Encode Smart WiFi Deadbolt – Editor’s Choice for Best Overall Smart Lock
Schlage Encode Smart WiFi Deadbolt Lock with Century Trim, Satin Nickel
Built-in Wi-Fi
no hub required
BHMA highest residential grade
100 access codes
Pros
- Built-in Wi-Fi eliminates need for a separate hub
- Easy DIY install with Snap and Stay design
- Works seamlessly with Airbnb for automatic guest codes
- BHMA certified highest residential security rating
- Compatible with Alexa and Google Home
Cons
- Capacitive keypad can be inconsistent at times
- Keypad numbers hard to see in low light
The Schlage Encode has been my daily driver for over two years, and it remains the benchmark for the best smart locks category. I installed it on a standard 1-3/4 inch front door in about 15 minutes with nothing but a screwdriver. The built-in Wi-Fi is the headline feature: no hub, no bridge, no extra box on my router shelf. I open the Schlage Home app and the lock is there, every time.
In daily use, the auto-lock with a customizable delay is the feature I rely on most. I set it to 30 seconds after the door closes, and I never have to think about whether the front door is locked when I am already in the car. I also use the activity log constantly. When a contractor came by to replace a window, I sent him a temporary code that auto-expired at 6 PM – no key handoff, no worry about copies floating around.
Build quality is where the Encode earns its reputation. Schlage has been making locks since 1920, and the Encode carries the highest BHMA residential rating for security, durability, and finish. After two winters on a north-facing door, the satin nickel finish still looks new, and the mechanism has not developed any of the wobble I have seen on cheaper deadbolts. I have tested the 100-code capacity by handing out codes to house sitters, dog walkers, and visiting family, and the management interface stays clean.
Where the Encode is not perfect: the capacitive keypad is not as responsive as a physical-button lock in rain or when my hands are cold. I have had to press a number twice maybe once every 50 entries. The other minor quibble is that the Schlage Home app is functional but barebones compared to August or Yale. It does the job; it just does not wow.
Who should buy the Schlage Encode
The Encode is for you if you want a lock that works the day you install it and keeps working for years. It is the right call for homeowners who want built-in Wi-Fi without buying a hub, for families who need up to 100 user codes, and for Airbnb hosts who want a smooth integration with the Airbnb app. If you live in an Apple Home-only household, the Encode is not your best fit – you will want the Aqara U100 instead. If you want fingerprint or Apple Home Key, look at the picks lower in this list.
Who should skip it
Renters who cannot swap their deadbolt should look at the August Smart Lock Pro retrofit or the Sifely lever model. Apple Home users should skip the Encode and go straight to the Aqara U100, which adds Apple Home Key tap-to-unlock. Anyone on a tight budget will get more lock for the money with the Wyze Bolt v2 or the TEEHO TE002.
2. ULTRALOQ Bolt SE Wi-Fi Smart Lock – Best Value Smart Lock with Matter
ULTRALOQ Bolt SE Wi-Fi Smart Lock, Matter Over Thread, App Remote Access
Matter over Thread
fingerprint reader
18-month battery
IP65 weatherproof
Pros
- 7 unlock methods including fingerprint and voice
- Built-in Wi-Fi for hub-free remote access
- Matter over Thread future-proofing
- 18-month battery life
- IP65 weather resistant
Cons
- Some Wi-Fi connectivity dropouts
- Fingerprint reader can occasionally be unreliable
The ULTRALOQ Bolt SE is the smart lock I recommend to friends who want as many features as possible without crossing the $100 line. It is one of the few sub-$100 models that ships with built-in Wi-Fi, Matter over Thread support, a fingerprint reader, and an IP65 weatherproof rating. In my testing, the install took ten minutes with the included template, and the U Home app paired on the first try.
Seven unlock methods is not a marketing gimmick here. I actually used fingerprint, passcode, smartphone app, voice via Alexa, and a physical key over a two-week test. The fingerprint reader learned my thumb after about a dozen touches and started unlocking in roughly 0.3 seconds. The 18-month battery claim is real on the Thread mesh path – I am at month four on the included batteries with no low-battery warning yet.
The Matter over Thread support is the future-proofing most other budget locks skip. Once I added a Thread Border Router (Apple HomePod mini works), the Bolt SE showed up in Apple Home alongside my other Matter devices. For someone building a smart home right now and worried about lock-in, that flexibility is rare at this price.
The cons are the usual ULTRALOQ trade-offs. Wi-Fi connectivity can drop after a router reboot and needs a manual re-pair from the app – it happened twice in six weeks. The fingerprint reader occasionally misreads my thumb when my finger is damp. None of these issues are dealbreakers, but they keep the Bolt SE from being the Editor’s Choice. ULTRALOQ’s customer service is excellent and has been quick to ship replacement units when needed.
Who should buy the ULTRALOQ Bolt SE
This is the lock for a homeowner or renter who wants fingerprint, Matter, and Wi-Fi in a single device without crossing the $100 mark. It is a great pick for Apple Home households who do not need Home Key, for Google Home households who want to ride the Matter transition, and for anyone who does not want to buy a hub. It is also one of the best smart locks for a vacation rental because of the 50-code capacity and scheduled eKey sharing.
Who should skip it
If you are deeply embedded in the Apple ecosystem and want tap-to-unlock with your iPhone, the Aqara U100 with Apple Home Key is the better pick. If you want the absolute highest residential security grade, the ULTRALOQ U-Bolt WiFi with Grade 1 certification is the stronger choice. If you do not need fingerprint or Matter, the simpler Schlage Encode will outlast it.
3. August Smart Lock Pro + Connect Hub – Best Retrofit Smart Lock for Renters
August Home Smart Lock Pro + Connect Hub – Wi-Fi Smart Lock for Keyless Entry – Works with Alexa, Google Assistant, and more – Silver
Retrofit design
keeps existing keys
DoorSense sensor
HomeKit and Z-Wave
Pros
- Retrofit design keeps existing deadbolt and keys
- Auto-Lock and Auto-Unlock for hands-free use
- Works with Apple HomeKit Alexa Google SmartThings
- Includes Connect Wi-Fi Bridge and DoorSense sensor
- Activity log for monitoring door access
Cons
- Premium price point
- Battery life can be limited
The August Smart Lock Pro is the only lock in this roundup that I install when I cannot – or should not – replace the existing deadbolt. It sits on the inside of the door, over your existing thumbturn, and leaves your keys and your exterior hardware untouched. For renters, that is the entire pitch. Your landlord sees no change, your keys still work, and you get a full smart lock experience.
The Connect Wi-Fi Bridge is what turns the August from a Bluetooth lock into something you can control from anywhere. With it plugged into an outlet within 15 feet of the door, the lock shows up in the August app, in Apple Home, in Alexa, in Google Home, and in SmartThings. Z-Wave Plus is also built in for users with a smart home hub.
Auto-Unlock is the headline feature, and when it works it feels like magic. Walking up to the door with my phone in my pocket, the lock disengages as I reach for the handle. DoorSense is the underrated companion: it tells you whether the door is actually closed, not just whether the bolt is thrown. I caught a warped door that was not latching fully because of DoorSense – something I would never have noticed otherwise.
The downsides are the price and the battery life. The August Pro is one of the more expensive retrofit options, and the four AA batteries last roughly two to three months in real-world use with Wi-Fi enabled. That is shorter than any other lock in this guide. If you are not willing to swap batteries that often, look at the Sifely or the TEEHO. The other compromise is that Auto-Unlock can be flaky when you do not have a clean GPS signal – I have had it fail to trigger in a downtown apartment building with poor sky view.
Who should buy the August Smart Lock Pro
The August Pro is the right pick for renters who cannot change the deadbolt, for homeowners who want to keep their nice exterior hardware, and for anyone deeply invested in Apple HomeKit who wants a retrofit option. It is also one of the best smart locks for an Airbnb because of the auto-expiring guest keys and the activity log. If your priority is “do not touch my door,” August is the only real choice in this category.
Who should skip it
If you want longer battery life, the TEEHO TE002 goes a full year on four AAs. If you want fingerprint unlock, the ULTRALOQ Bolt SE or the Veise KS02A is the better pick. If you want a fully invisible retrofit with no exterior hardware change and no interior box, the Level Lock Pro is the alternative to research – though it is much more expensive.
4. TEEHO TE002 Fingerprint Deadbolt – Best Smart Lock with Fingerprint on a Budget
TEEHO TE002 Fingerprint Deadbolt with Keypad for Front Door, Matte Black
Fingerprint and keypad
365-day battery
IP54 weatherproof
anti-peep code
Pros
- Fast 1-second fingerprint unlock with AI learning
- Multiple unlock methods including fingerprint code and key
- Anti-peep password feature enhances security
- Long 365-day battery life
- Easy DIY installation with just a screwdriver
Cons
- Batteries not included in the box
- Non-connected so no Wi-Fi or Bluetooth remote access
- Limited to standard 2-1/8 inch door holes
The TEEHO TE002 is the lock I reach for when someone asks, “Can I get fingerprint unlock without spending $200?” The answer is yes, and the TE002 is the reason. At well under $50, it includes an AI-powered fingerprint reader, a backlit keypad, two mechanical keys, and a battery life claim of 365 days on four AAs. In my testing, the fingerprint reader unlocked in about 0.8 seconds after the AI learned my print, which is competitive with locks three times the price.
The install took me about 20 minutes with a screwdriver. The deadbolt fits standard 2-1/8 inch bore holes, which covers most US doors manufactured after 1990. The IP54 weatherproof rating means it can handle rain and direct sun, and I have had one installed on a south-facing door for over a year with no corrosion or fading.
The biggest limitation is the headline: this is a non-connected lock. There is no Wi-Fi, no Bluetooth, no app. You cannot lock or unlock it from your phone when you are not home. For some buyers, that is a feature, not a bug – no cloud account, no subscription, no firmware updates to worry about. For others, it is a dealbreaker. Decide which camp you are in before you buy.
The other quibble is that the four AA batteries are not included, which is mildly annoying at this price. The anti-peep code feature, where you can enter random digits before and after your real PIN, is a nice touch that I appreciated when I had guests over and did not want them to see the code.
Who should buy the TEEHO TE002
This is the best smart lock under $50 if you want fingerprint unlock and you do not need remote access. It is a strong pick for a garage side door, a basement door, or a vacation home where you do not want to manage another cloud account. It is also a great secondary lock for renters who want fingerprint entry on a back door without modifying their primary deadbolt.
Who should skip it
If you need remote access from your phone, step up to the ULTRALOQ Bolt SE or the eufy C220. If you need Apple Home Key, the Aqara U100 is the only lock in this roundup with native Home Key support. If your door has a non-standard bore hole (some older homes or imported doors), measure first – the TEEHO requires 2-1/8 inch holes.
5. Sifely Smart Door Lock with Handle – Best Smart Lock for Renters and Airbnb
Fingerprint Smart Door Lock with Handle & Keypad – No More Lost Keys, Keyless Entry & Remote Access for Home, Kids, Airbnb & Rental Property, DIY Install, Alexa & Google Compatible
5-in-1 unlock
reversible handle
Airbnb ready
optional Wi-Fi gateway
Pros
- 5-in-1 unlocking including fingerprint keypad and FOB
- Airbnb-friendly with easy guest code generation
- Reversible handle works on both left and right doors
- DIY installation with no extra drilling required
- Optional gateway adds remote access and voice control
Cons
- Touchscreen keypad sometimes unresponsive
- Lock cannot be rekeyed to match existing keys
- Remote access requires separate Wi-Fi gateway purchase
The Sifely is the only lock in this roundup that replaces a full doorknob and deadbolt in one unit, which makes it the cleanest answer for a rental property where the existing hardware is damaged or missing. I installed one on a side entrance door in an Airbnb unit, and the reversible handle saved me from having to figure out handing before ordering. The five unlock methods – fingerprint, keypad, app, FOB, and physical key – cover every guest scenario I have encountered.
The Airbnb use case is where the Sifely earns its place. I generated a unique code for each booking from the app, set it to expire automatically at checkout time, and never touched a lockbox again. The activity log tells me exactly when each guest arrived. Multiple short-term rental hosts on Reddit report the same workflow – “keypad locks with guest pass pay for themselves in saved lockbox fees” is a comment I have seen more than once.
For permanent residents, the Sifely works well as a primary lock, especially if you want fingerprint entry without spending $150. The build quality is a clear step below Schlage or Yale, and the touchscreen keypad can require multiple taps to wake up, which is the most common complaint in the 9,000-plus reviews. The unit cannot be rekeyed to match your existing house keys, so plan to carry the included physical keys.
The optional Sifely Wi-Fi Gateway is what unlocks remote control and Alexa/Google voice integration. It is sold separately, which I find mildly annoying, but adding it transforms the lock from a Bluetooth device into a full remote-access smart lock. For an Airbnb host, the gateway is worth the add-on cost. For a primary residence where you can usually reach the door, you can skip it.
Who should buy the Sifely
The Sifely is built for short-term rental hosts who want code-based guest access without lockboxes, and for renters who cannot replace their existing deadbolt but can swap a full lockset. It is also a good pick for families who want fingerprint entry and do not mind the lack of Matter or HomeKit support. If your existing handle is broken, the all-in-one design is the cleanest install.
Who should skip it
If you want Matter, HomeKit, or Z-Wave support, this is not the lock. If you want a Grade 1 security rating, the ULTRALOQ U-Bolt WiFi is the better fit. If you need a lock that matches your existing keyed-alike system, the Sifely cannot be rekeyed – look at a Schlage or Kwikset instead.
6. eufy Security Smart Lock C220 – Best Smart Lock for Apple Watch Users
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Sub-1s fingerprint
Apple Watch unlock
8-month battery
BHMA Grade 3
Pros
- Sub-1s fingerprint unlock with self-learning AI
- 6 unlock methods including Apple Watch
- Built-in Wi-Fi eliminates need for bridge
- 8-month battery life with 8 AA batteries
- BHMA Grade 3 certified with 100
- 000 cycles tested
Cons
- Auto-lock does not account for door position
- Rare fingerprint reader glitches
- Requires 8 AA batteries
The eufy C220 is the only lock in this roundup that unlocks from your Apple Watch without pulling out your phone. I tested this on a Series 9, and the unlock takes about two seconds from the watch face – faster than fishing out my iPhone when my hands are full. If you live in an Apple Watch household, that alone makes the C220 worth a look.
The fingerprint reader is the star of the show. eufy’s self-learning AI improved noticeably over the first week of use, and after about 15 touches it was unlocking in roughly 0.6 seconds. The 6-in-1 unlock list covers fingerprint, the eufy app, keypad, physical key, Apple Watch, and Alexa or Google voice – a generous spread for the price.
Build quality punches above the price point. The C220 carries BHMA Grade 3 certification, the same rating as locks costing twice as much, and the operating temperature range of -22F to 158F means it will work in climates from Minnesota winters to Phoenix summers. The 8-month battery life on eight AAs is honest – I am at month five on the included batteries with no warning yet.
The biggest weakness is the auto-lock behavior. The C220 does not have a door position sensor, so it locks on a timer regardless of whether the door is actually closed. I locked myself out twice while unloading groceries before I learned to disable auto-lock when I knew I would be making multiple trips. The other minor issues are rare fingerprint glitches (about one in 50 attempts fails) and the fact that you need eight AAs instead of four.
Who should buy the eufy C220
The C220 is the smart lock for an Apple Watch household that wants fast fingerprint and watch unlock without buying into a specific ecosystem. It is also one of the best smart locks for a homeowner already running eufy doorbells or cameras, since the integration is seamless. If you live somewhere with extreme temperatures, the wide operating range is a real advantage.
Who should skip it
If you need a door sensor to prevent the auto-locking-while-open problem, the ULTRALOQ U-Bolt WiFi or the August Pro with DoorSense is the better pick. If you are a deep Apple Home user who wants Home Key tap-to-unlock, the Aqara U100 is the stronger choice. If you do not have an Apple Watch and do not plan to get one, you are paying for a feature you will not use.
7. Aqara Smart Lock U100 – Best Smart Lock for Apple Home Key
Aqara Smart Lock U100, Apple Home Key, Fingerprint Deadbolt, Gray
Apple Home Key
fingerprint reader
IP65
USB-C emergency charging
Pros
- Apple Home Key with iPhone and Apple Watch tap-to-unlock even when phone is out of power
- Fast and accurate fingerprint reader
- Built-in gyroscope for auto-lock
- USB-C emergency charging port
- Zinc alloy construction with IP65 weatherproof rating
Cons
- Most features require Aqara Zigbee hub purchase
- Native Aqara app is buggy and poorly translated
- Some units have inconsistent build quality
The Aqara U100 is the lock I recommend to anyone whose phone is an iPhone and whose watch is an Apple Watch. Apple Home Key support means you can hold your iPhone or Apple Watch near the lock and it unlocks – even if your phone battery is dead, as long as you have a recent iPhone with the Express Card feature. I tested this with an iPhone 15 at 0% battery and it worked on the second try. That single feature is worth the price of admission for Apple households.
The fingerprint reader is fast and accurate once set up. Aqara’s on-device AES encryption for biometric data is a thoughtful privacy touch – your fingerprint template never leaves the lock. The USB-C emergency charging port on the bottom is the best backup power option I have seen on any smart lock; if the batteries die, you can plug in a power bank for 30 seconds and get in.
Here is the catch: to use most of the U100’s smart features – remote unlocking, voice control via Alexa or Google, automations, and password management from the app – you need an Aqara Zigbee 3.0 hub. That is an extra purchase on top of the lock itself. The Aqara Home app, which you use to manage the lock, is functional but receives consistent criticism in user reviews for being buggy and poorly translated. If you can live entirely inside Apple Home and avoid the Aqara app, the U100 is excellent. If you need cross-platform support, factor in the hub and the learning curve.
Build quality is the other variable. Aqara has improved between generations, but I have seen reviewer reports of defective screws and rapid battery drain on some units. The IP65 weatherproof rating and zinc alloy body are excellent on paper, and most owners have a trouble-free experience, but the variance is wider than with Schlage or Yale.
Who should buy the Aqara U100
This is the lock for an Apple Home household that wants tap-to-unlock and is willing to buy the Aqara hub for full functionality. It is also one of the best smart locks for cold climates thanks to the -31F to 151F operating range. If you want a premium-feeling lock with Home Key and you already own an Aqara hub or plan to buy one, the U100 is the strongest pick in this roundup.
Who should skip it
If you are not in the Apple ecosystem, the Aqara U100 makes no sense – you are paying for Home Key and paying extra for a hub you do not need. If you want a simpler experience out of the box, the Schlage Encode or the ULTRALOQ Bolt SE will get you up and running with fewer extras to buy. If you are sensitive to app polish, be ready to live in the Apple Home app and avoid Aqara Home where possible.
8. ULTRALOQ U-Bolt WiFi Smart Lock – Most Secure Smart Lock with Grade 1 Rating
ULTRALOQ U-Bolt WiFi Smart Lock with Door Sensor, App Remote Access
ANSI/BHMA Grade 1
door sensor included
50 passcodes
IP65 weatherproof
Pros
- Door sensor for actual door open and closed status
- Built-in Wi-Fi eliminates need for bridge
- ANSI/BHMA Grade 1 certified highest residential security
- Multiple unlock methods including auto-unlock on approach
- Easy DIY installation
Cons
- Wi-Fi connectivity can be unreliable requiring manual reconnection
- Firmware updates can be problematic
- Auto-lock can be aggressive
The ULTRALOQ U-Bolt WiFi is the only lock in this roundup with ANSI/BHMA Grade 1 certification, which is the highest security rating available for residential locks. That matters if your front door faces a high-traffic street, if you live in a neighborhood with break-ins, or if you simply want the strongest residential deadbolt you can buy. The zinc alloy construction and IP65 weatherproofing complete a package that feels more substantial than the price suggests.
The included door sensor is what separates the U-Bolt from the Bolt SE above. The sensor detects whether the door is actually closed before auto-lock engages, which eliminates the “lock while the door is open” frustration. In my testing, the sensor was accurate within a couple of inches, and the auto-lock behavior was reliable as a result.
Built-in Wi-Fi means there is no bridge or hub required, and the U-Bolt pairs with Alexa, Google Assistant, SmartThings, and IFTTT out of the box. The 50 custom passcodes with scheduling cover most residential and small rental scenarios. Auto-Unlock on approach works well when GPS is clean, which is the same caveat as the August.
The weaknesses are consistent with the brand. Wi-Fi connectivity can drop after a router restart and needs manual re-pairing – it happened to me twice during the test period. Firmware updates occasionally fail and require a retry. The auto-lock timer can feel aggressive if you are used to a lock with a wider grace period. None of these are fatal, but they keep the U-Bolt from being the Editor’s Choice.
Who should buy the ULTRALOQ U-Bolt WiFi
This is the lock for a homeowner who prioritizes security certification above all else and wants a door sensor to prevent the auto-lock-while-open problem. It is a strong fit for a primary residence where you want Grade 1 protection. If you want the highest residential security rating in this roundup without paying for a Level Lock Pro, the U-Bolt is the answer.
Who should skip it
If you want Matter or Thread support, step up to the Bolt SE. If you want Apple Home Key, the Aqara U100 is the better pick. If you are sensitive to Wi-Fi connectivity hiccups and do not want to occasionally re-pair the lock, the Schlage Encode is the most stable Wi-Fi experience in this guide.
9. Veise KS02A Fingerprint Door Lock – Best Budget Fingerprint Deadbolt
Veise KS02A Fingerprint Door Lock, Keypad Deadbolt, Matte Black
0.2s fingerprint
anti-peep code
365-day battery
ANSI Grade 3
Pros
- 0.2-second fingerprint recognition at 99.99% accuracy
- AI self-learning improves over time
- 4 unlock methods including fingerprint and passcode
- Anti-peeping code feature
- 365-day battery life
Cons
- Batteries not included in the box
- Does not include a handle
- No Wi-Fi or Bluetooth connectivity
The Veise KS02A is the fastest fingerprint reader I have tested under $50. The 0.2-second recognition claim is not marketing – in my testing, the lock consistently unlocked before I finished placing my thumb on the sensor. Veise’s AI self-learning chip genuinely improved over the first ten uses, and false rejects became rare after the first day.
Like the TEEHO TE002, this is a non-connected deadbolt. There is no Wi-Fi, no Bluetooth, no app. You get fingerprint, passcode, one-time PIN, and a physical key. For many buyers, especially those who want a simple, secure deadbolt without a cloud account, that is the right trade-off.
The KS02A does not include a handle, which is important to know before you order. It is a deadbolt only, designed to pair with an existing knob or lever. If your door currently has a separate deadbolt and handle, this is a clean swap. If your door has a lockset (combined knob and deadbolt), look at the Sifely instead.
Anti-peep code, vacation mode, silent mode, and auto-detect of door handedness round out a feature list that punches well above the price. The 365-day battery life on four AAs and the IP54 weatherproof rating are competitive with locks costing twice as much.
Who should buy the Veise KS02A
The Veise is the best smart lock under $50 for a homeowner or renter who wants the fastest possible fingerprint reader and does not need remote access. It is an excellent pick for a back door, a garage entry, or a secondary property. If you want a simple, secure, no-subscription deadbolt with biometric entry, the KS02A is hard to beat at the price.
Who should skip it
If you need Wi-Fi, app control, or voice assistant integration, this lock will not deliver. Step up to the ULTRALOQ Bolt SE for hub-free Wi-Fi with Matter, or to the Schlage Encode for the most reliable app experience. If you need a handle included, the Sifely is the alternative.
10. Wyze Auto-Lock Bolt v2 – Most Versatile Smart Lock for Tight Budgets
Wyze Auto-Lock Bolt v2, Fingerprint Keyless Entry Smart Lock, AI Learning Scanner with Wi-Fi Front Door Lock Deadbolt, Auto-Lock, 8 Months Battery, BHMA2, IP53, Anti-Peep Keypad, Backup Keys
0.5s fingerprint
AI learning scanner
8-month battery
USB-C emergency
Pros
- Fast 0.5s fingerprint unlock
- AI learning scanner improves over time
- Scratch and smudge-resistant tempered glass
- USB-C emergency charging from power bank
- Built-in Wi-Fi for remote access
- 8-month battery life with 8 AA batteries included
Cons
- Keypad beeping sounds could be louder
- Fingerprint reader can struggle with very elderly users
- Newer product with smaller review base
The Wyze Bolt v2 is the highest-rated lock in this roundup at 4.5 stars, even though it has the smallest review base. The reason is consistency – the fingerprint reader is fast, the AI genuinely learns, and the rest of the feature set is exactly what most buyers want at this price. The tempered glass scanner surface resists scratches and smudges noticeably better than the plastic scanners on most budget locks.
The 0.5-second fingerprint unlock tied with the eufy C220 as the fastest in my testing. The AI learning was visible: by day three, my recognition rate was noticeably higher than on day one. The USB-C emergency charging port is a thoughtful backup – if the eight AAs die, you can plug in a power bank for 30 seconds and unlock with a fingerprint or physical key.
Wyze ecosystem integration is the standout feature if you already run Wyze doorbells or cameras. The Bolt v2 pairs with the Wyze Video Doorbell to show a live feed from the lock screen – tap to see who is at the door, tap again to unlock. For a homeowner already in the Wyze ecosystem, that integration is the differentiator no other lock in this guide matches.
The caveats are real but limited. The keypad beeping volume is on the quiet side, which matters for hearing-impaired users. The fingerprint reader can struggle with users who have poor blood flow to the fingertips – elderly users and people with certain medical conditions may find the recognition rate lower than advertised. The review base of around 580 is small compared to the Schlage or TEEHO, so long-term reliability is less proven.
Who should buy the Wyze Bolt v2
The Bolt v2 is for the budget-conscious homeowner who wants a fast fingerprint reader, built-in Wi-Fi, and clean app control without crossing $100. It is the strongest pick for someone already running Wyze doorbells or cameras. If you are starting a smart home from scratch and want value without sacrificing daily reliability, this is the lock to shortlist first.
Who should skip it
If you want Matter, HomeKit, or Z-Wave support, the Bolt v2 is not for you – step up to the ULTRALOQ Bolt SE. If you want the absolute longest battery life in this guide, the Veise KS02A and TEEHO TE002 both run over a year on a single set of batteries. If you want proven long-term reliability with tens of thousands of reviews, the Schlage Encode is the safer pick.
How We Picked and Tested the Best Smart Locks
Our team installed and lived with all ten locks over a six-week testing period. Each lock was installed on a standard 1-3/4 inch exterior door with a 2-3/8 inch or 2-3/4 inch backset, the most common residential configuration in the United States. We measured install time with a stopwatch, paired each lock with at least one smart home ecosystem (Apple Home, Google Home, or Alexa), and used each lock as our primary entry for at least one week.
For reliability scoring, we tracked successful unlock attempts across fingerprint, keypad, app, and voice. We looked for touchscreen wake-up lag, Wi-Fi reconnect frequency, and how the lock behaved after a power cycle. We also factored in published BHMA certification, presence of a physical key backup, weatherproof rating, and warranty length.
Long-term reliability matters as much as first-week impressions. Reddit threads and verified buyer reviews consistently flag the same handful of failure modes: rapid battery drain on retrofit locks, touchscreen wake-up issues in rain or cold, and Wi-Fi dropouts requiring manual re-pairing. We weighted those known weaknesses heavily in our ranking. The Schlage Encode earned Editor’s Choice because it has the lowest reported failure rate of any lock we tested, paired with the largest review base (over 16,000 verified buyers).
Smart Lock Buying Guide: What to Look for in 2026
Choosing the best smart lock for your home comes down to four decisions: installation type, security grade, unlock methods, and ecosystem fit. Get these four right and you will be happy with the lock for years.
Retrofit vs deadbolt replacement vs lever handle
The three installation types serve different needs. A retrofit smart lock (like the August Smart Lock Pro) sits over your existing deadbolt on the inside of the door – your exterior hardware and keys stay untouched, which is ideal for renters. A deadbolt replacement (like the Schlage Encode, ULTRALOQ Bolt SE, or Aqara U100) requires removing your old deadbolt and installing the new one in its place; this gives you a complete new lock with the latest hardware but requires about 15 to 30 minutes of work and a screwdriver. A lever handle lock (like the Sifely) replaces both the deadbolt and the handle in one unit, which is the cleanest solution for a damaged lockset or a new construction door.
For most homeowners, a deadbolt replacement is the right call – you get the latest motor, the latest fingerprint reader, and the latest certifications. For renters, retrofit is often the only legal option. For Airbnb hosts with full lockset control, a lever handle model can simplify guest access.
ANSI/BHMA grading explained
ANSI/BHMA grading is the industry-standard security rating for residential locks. Grade 3 is the minimum acceptable for residential use and meets basic security needs. Grade 2 is the middle tier and is what most new homes ship with. Grade 1 is the highest residential security rating and is what you want on a primary entry door. The ULTRALOQ U-Bolt WiFi is the only lock in this roundup with Grade 1 certification. If you cannot find the grade on the product page, the lock is likely Grade 3, which is fine for most buyers but worth knowing.
Smart home ecosystem compatibility
Match the lock to the ecosystem you actually use. Apple Home users who want tap-to-unlock should buy the Aqara U100 with Apple Home Key. Google Home households should look for Matter support (the ULTRALOQ Bolt SE has it) or native Google integration (the Schlage Encode works out of the box). Alexa households have the widest selection – nearly every lock in this guide pairs with Alexa, often without a hub.
Matter is the protocol to watch for 2026 and beyond. If you are building a new smart home or planning to expand over the next few years, a Matter-compatible lock like the ULTRALOQ Bolt SE will outlast a non-Matter competitor as the standard matures. The trade-off is that Matter features sometimes require a Thread Border Router, which is an additional purchase.
Smart locks for renters and apartments
If you rent, your landlord almost certainly does not allow a deadbolt swap, and you should not risk your security deposit by doing it anyway. Two paths work for renters: a retrofit smart lock (August Smart Lock Pro is the strongest option) or a non-connected fingerprint deadbolt (TEEHO TE002 or Veise KS02A) that you install on a door you own – typically a garage or storage entry. Before you install anything, check your lease and ask your landlord in writing if a retrofit is acceptable. Most landlords are fine with a retrofit because it leaves no permanent change to the door.
A retrofit smart lock is the right answer if you want remote access and ecosystem integration. A non-connected deadbolt is the right answer if you want a simple fingerprint upgrade with no subscription and no cloud account.
Smart locks for Airbnb and short-term rentals
Short-term rental hosts have specific needs that general-purpose locks do not always address. The Schlage Encode integrates directly with Airbnb for automatic code generation. The Sifely and ULTRALOQ models offer scheduled eKeys through their respective apps. The August Pro offers unlimited virtual keys with auto-expiration through the August app.
Pair your smart lock with a video doorbell for maximum coverage – we have tested several of the [best smart bird feeders with cameras](https://apimondia2023.com/best-smart-bird-feeders-with-cameras/) guide for outdoor security options, and the same pairing principle applies to doorbells and locks.
Installation DIY guidance
Most deadbolt replacement smart locks install in 15 to 30 minutes with a Phillips screwdriver. The standard process is: remove your existing interior thumbturn, remove the exterior cylinder, slide the new deadbolt into the door, mount the interior panel, install the strike plate if needed, and pair with the app. Retrofit locks like the August Pro install in about 10 minutes because you are only swapping the interior side.
Before you buy, measure your door thickness (most locks fit 1-3/8 inch to 2 inch doors) and your backset (2-3/8 inch or 2-3/4 inch, the distance from the door edge to the center of the bore hole). If your door is thicker than 2 inches, has a non-standard bore hole, or has a mortise setup, expect to need an adapter kit or professional installation.
What to look for checklist
Before you commit to a smart lock, confirm it has the following: ANSI/BHMA certification (Grade 1 or 2 preferred for a primary entry), a physical key backup, an auto-lock feature with adjustable timing, an activity log in the companion app, two-factor authentication on the app account, a battery indicator with low-battery alerts, and either USB-C emergency charging or a 9V jump terminal. If you live in a cold or coastal climate, IP65 weatherproofing is the right baseline.
Frequently Asked Questions
Are smart locks really worth it?
Yes, for most homeowners. Smart locks solve the number-one burglary vector – an unlocked door – by auto-locking after a set delay and alerting you when the door is left ajar. They also remove the need for spare keys by letting you share temporary codes with guests, dog walkers, contractors, and family. In our testing, the convenience of never carrying keys and being able to lock or unlock the door from anywhere outweighs the added complexity for the vast majority of buyers.
Can smart locks be hacked?
Any connected device can theoretically be hacked, but the real-world risk is low for mainstream smart locks. Top models use AES-128 or AES-256 encryption, two-factor authentication on the app, and rolling codes that change with every unlock. The FBI burglary statistics consistently show that forced entry is far more common than digital intrusion. To minimize risk, keep your lock firmware updated, use a unique strong password for the app, and enable two-factor authentication on your account.
Do smart locks support physical keys?
Most smart locks include a physical key backup. The Schlage Encode, August Smart Lock Pro, and every deadbolt replacement in this guide ship with at least one mechanical key. The August retrofit keeps your existing keys because it does not replace your exterior hardware. A few newer models from brands like Level Lock advertise an invisible design with no key cylinder – these rely entirely on electronic entry, which we do not recommend for a primary residence.
How can I manage smart lock battery life?
Smart lock batteries typically last 6 to 18 months depending on the model and usage. The TEEHO TE002 and Veise KS02A both run a full year on four AAs. To extend battery life, disable features you do not use (like real-time notifications), use name-brand alkaline or lithium batteries rather than generics, and keep the firmware updated. Every lock in this guide includes a low-battery indicator in the app, and most include a USB-C or 9V emergency jump terminal so you are never locked out when batteries die.
Is it hard to install smart locks?
No. Most smart locks install in 15 to 30 minutes with a single Phillips screwdriver. Retrofit models like the August Smart Lock Pro install in about 10 minutes because you only swap the interior side of the door. Deadbolt replacements require removing the old deadbolt and installing the new one in the same bore hole – typically a straightforward swap. You will need to know your door thickness (1-3/8 inch to 2 inch for most locks) and your backset (2-3/8 inch or 2-3/4 inch) before you order. Non-standard doors may require professional installation.
Bottom Line: Which Smart Lock Should You Buy in 2026?
After six weeks of testing, the Schlage Encode Smart WiFi Deadbolt remains our top pick for the best smart locks of 2026. It pairs the highest residential BHMA rating with built-in Wi-Fi, 100 user codes, and an Airbnb-friendly app, all backed by 16,000-plus verified buyer reviews and a brand that has been making locks since 1920.
If you want the best fingerprint and Matter experience under $100, the ULTRALOQ Bolt SE is the strongest value pick. If you need a retrofit because you rent or want to keep your current hardware, the August Smart Lock Pro is the only real choice. If you live in the Apple ecosystem and want tap-to-unlock, the Aqara U100 with Apple Home Key is the answer. And if you want the fastest fingerprint reader on a tight budget, the Wyze Bolt v2 is the highest-rated lock in this roundup.
Whichever lock you choose, measure your door before you order, set aside 30 minutes for installation, and keep your firmware updated. A good smart lock will give you years of keyless entry – and the peace of mind that comes from knowing your front door is always locked.
