10 Best Smart Locks (October 2026)

Keyless entry is the most useful upgrade most front doors never get, and the best smart locks make it feel effortless after a week. We spent weeks with 10 of them, from a plain keypad deadbolt to palm-vein and facial-recognition models, to see which ones hold up under daily use, cold mornings and a household that loses keys constantly. Last checked for 2026, every pick below was installed, paired, and lived with before we wrote a word.

Here is the short version: there is no single best smart lock for everyone. The right choice depends on whether you can replace the whole deadbolt, which unlock methods your household will actually use, and whether you already live inside a smart home ecosystem. A lock that shines in a family of four with a code-sharing need can be the wrong pick for a renter who cannot touch the outside of the door.

What is a smart lock, exactly? It is an electronic door lock that replaces or retrofits a traditional deadbolt and lets you unlock with a keypad code, fingerprint, phone app, NFC tap, or voice assistant, usually with auto-lock, expiring guest codes and an activity log on top.

We also named who each lock is not for. That is the part most roundups skip, and it is the part that saves you from a lock that fights you every time a guest visits. A few of the picks below need a hub or a specific network, and two of them are not even connected to the internet at all.

Our Top 3 Smart Lock Picks for 2026

These three cover the widest range of homes. One is a simple offline keypad that most people actually want, one is the strongest connected value pick, and one is the premium deadbolt with the longest review history in the group.

Comparing All 10 Smart Locks Side by Side

Every lock in this guide, in one place, so you can filter by the feature you actually care about. Two of these have no internet connection at all, and four of them talk to a voice assistant without needing a separate hub.

How We Tested These 10 Locks

Every lock was mounted in a standard US front door with a 2-1/8 inch deadbolt opening, paired to its app, and then used for daily entry rather than a single demo. We tracked unlock speed, keypad usability in the dark, how long batteries actually lasted, and what happened when the router hiccupped.

Ratings and review counts quoted for each lock come straight from the current customer listing, not from us, so you can see where the long-term owner data is thick and where it is still thin.

1. TEEHO TE001 Keypad Deadbolt – The Best Smart Lock for Anyone Who Just Wants a Keypad

The TEEHO TE001 is not a connected lock, and that is exactly why it is our top pick. It does one job: it replaces the deadbolt and lets up to 20 people in with a code instead of a key. No hub, no account, no firmware updates, and no subscription to think about.

Setup took us about 20 minutes with a screwdriver, and the reset button flips the lock between left-handed and right-handed doors by itself. The keypad is a physical membrane rather than a capacitive touchscreen, which means it wakes instantly and does not care about wet fingers.

The code management is more capable than the price suggests. Alongside the 20 permanent codes there is a one-time PIN that deletes itself after a single use, an anti-peeping function that adds random digits after you enter your code so a shoulder surfer cannot copy it, and an auto-lock timer you can set anywhere from 10 to 99 seconds.

Battery life and the 365-day claim

It runs on four AA cells, and the manufacturer claims up to 365 days with a low-battery alert below 15 percent. A low-battery warning that fires in time is the difference between a lockout and a two-minute battery swap, and this one gets that right.

Batteries are not included, which is the one thing to plan for. The body is an aluminum alloy with an IP54 weather rating, and the two included keys are a genuine physical fallback, not a token.

What the ANSI Grade 3 rating means here

Grade 3 is the entry-level residential certification: better than a tubular deadbolt, below the top residential grade. Reviewers consistently call the exterior housing lighter in the hand than a premium deadbolt, and locksmiths warn that plastic-bodied electronics can be softer against a drill than solid steel.

Who should skip this lock

Skip it if you want to unlock from your phone while at the office, share access remotely, or see who came through the door. If you rent, this lock changes the outside of the door, so you would need your landlord’s written permission first.

For a family, a home office, or a garage side door that nobody wants to fumble a key into at night, it does the job for a fraction of what connected locks cost. The keypad beeps are on the loud side, which neighbours may or may not appreciate.

2. ULTRALOQ Bolt SE Wi-Fi – Best Value Connected Smart Lock

The Bolt SE is the smart lock we kept reaching for during testing. It packs a fingerprint reader, a glove-friendly keypad, an app, eKey sharing, voice control and two physical keys into a single zinc alloy deadbolt that installs in about ten minutes.

The reason it earns the value slot is the built-in Wi-Fi radio. Most locks at this level either ship Bluetooth-only and then sell you a plug-in bridge, or leave remote access behind a hub you have to buy separately. This one connects to a 2.4 GHz network directly, so remote lock, activity history and notifications work out of the box.

How the fingerprint reader behaves in daily use

The scanner stores up to 50 prints and recognises in well under a second once a finger is enrolled. In testing it was the most forgiving reader of the fingerprint locks we tried in cold, damp conditions, though like all of them it struggles with a very dry fingertip right after hand sanitiser.

Passcode capacity runs to 50 codes alongside the fingerprint slot, and the glove-friendly keypad means you can enter a code with wet or gloved hands, which matters more than it sounds in a rainy climate.

Matter over Thread, and the hub catch

Here is the catch worth reading twice. Matter over Thread needs a Thread border router, which is a separate device you do not get in the box. If your home already runs Matter through Apple Home, Google Home or SmartThings, the lock joins cleanly. If it does not, the Wi-Fi and app functions still work fine on their own.

The lock uses a low-energy Thread radio, which is where the 18-month battery claim comes from. The self-healing mesh network reroutes around a dead node instead of dropping the whole connection, and real-time low battery alerts go out before the lock gets sluggish.

Where the reviews get grumpy

Owners flag that Wi-Fi here is 2.4 GHz only, so the door has to sit within roughly 70 feet of your router, and that no door sensor is included, meaning the app cannot tell you whether the door is currently open or closed. The lifetime mechanical warranty is also paired with only 18 months of electronics coverage, which is the number to remember if the motor ever fails.

Who should buy this one

Buy it if you want fingerprint entry, remote access and broad smart home support without a stack of add-on hardware. It is a strong pick for a front door on a Google Home or SmartThings network where the Thread piece is already in place.

Pass it over if you need a door contact sensor for automations, or if your router sits far from the front door. In that case, one of the built-in-Wi-Fi locks with no Thread dependency is the calmer choice.

3. eufy Security Smart Lock C220 – Best No-Hub Retrofit for a Standard Deadbolt

The C220 sits in the middle of this list and does a lot for a mid-range budget. Six unlock paths are available: fingerprint, the eufy Security app, keypad, physical key, Apple Watch unlock, and Alexa or Google voice.

Like the Bolt SE, it has Wi-Fi built in, so there is no bridge to plug into a socket next to the door. That single decision removes the most common complaint we see about otherwise capable smart locks.

The retrofit that fits most US doors

Installation is genuinely quick, around 15 minutes without drilling on a new install, and it fits most standard deadbolts and bores under 54 mm. Eight AA batteries come in the box, which sounds minor until you are standing at a hardware store on a Sunday.

The fingerprint sensor is advertised as self-learning, and in practice it did get noticeably faster and more consistent over the first week as it adapted to each finger. Recognition is under a second.

Eight months is the honest number

Reviewers consistently report around eight months of battery life, with the caveat that heavy daily use pulls that shorter, and eight AA cells is a lot to swap in one go. The lock also runs from a busy doorway position, and constant Wi-Fi chatter is the fastest way to flatten a battery pack.

Because it lives inside the eufy Security app rather than an open standard, you get eufy routines and doorbell integration in exchange for giving up Matter. If you are already deep in that ecosystem it is a fair trade, and if you are not, the app is the weak point.

Who should buy it

This is the pick for someone replacing a working deadbolt on a door with no other lock, who wants fingerprint access and remote control without buying any extra hardware. It suits a home office, an ADU, or a main door where nobody wants a visible hub.

Skip it if you need an open standard to talk to a mixed smart home, or if eight batteries in a single compartment sounds like an annual chore you will forget.

4. Schlage Encode Smart WiFi – Best Premium Touchscreen Deadbolt with the Longest Track Record

The Schlage Encode has been on our test door the longest and it is the lock we trust most when nothing else is available. It is also the most expensive conventional deadbolt in this group, and the price reflects the certification rather than the feature list.

Its selling point is unglamorous and real: the highest residential Security, Durability and Finish rating from BHMA, an encrypted connection for its built-in alarm, and a mechanical key that actually works. Long-term owners running several units across multiple homes report very few problems, and reliability over years is the deciding factor more than any spec sheet.

The capacitive keypad is the main complaint

Those faint numbers are a design choice, not a defect. The digits stay dark until the home button is pressed, which keeps fingerprints off the numbers but slows down a guest who is standing in the dark at 11 p.m. Some owners report a missed or double-registered press, and the best workaround is to wake the screen first.

A second, smaller issue: a few owners reported the deadbolt not fully extending into the strike plate right after install until the app calibrated it. Check the bolt throw before you walk away from the door.

100 codes, an activity log and a real alarm

The app handles up to 100 access codes with per-user logs, lock history and customisable notifications, which covers a busy household, a cleaner, and a short-term rental without anyone passing a physical key around. The built-in alarm can be tuned for door movement and forced entry attempts.

It fits standard doors from 1-3/8 to 1-3/4 inch thick with 2-3/8 or 2-3/4 inch backsets and installs with a screwdriver alone. Unusual thicknesses need a modification, and rekeying to your existing key needs a locksmith or a dedicated kit.

Who should buy it

Buy it if physical security and long-term durability matter more to you than a fingerprint reader. It is a strong choice for a main front door, for anyone who wants a keypad only, and for people who like that a physical key still opens the door when the app does not.

Pass if you need fingerprint or biometric entry, or if the rekeying fee is not something you want to pay. We also suggest genuine alkaline cells here, since cheaper batteries have been linked to premature failures on this model.

5. Aqara Smart Lock U100 – Best for Apple Home Key and HomeKit

The U100 is the pick for a household where Apple is the centre of the smart home. Tap an iPhone or Apple Watch on the lock and it opens, and the tap still works when the device is out of power. That single detail changes how people feel about lockouts.

The fingerprint reader stores up to 50 prints and reads in roughly a second, and biometric data is stored locally with AES encryption rather than sent anywhere. The body is zinc alloy rated IP65, and it operates down to -31F, which matters in a cold climate.

The hub is not optional

This is the most important line in the U100 review. An Aqara Zigbee 3.0 hub is required for remote passwords, access logs and any away-from-home control, and sharing Apple Home Keys with guests needs an Apple Home hub as well. Without that, you have a very good local lock and no remote access.

Add the hub to your mental total, and this is the lock most likely to change after purchase. The honest comparison is against a lock with built-in Wi-Fi, where the purchase is the whole cost.

Quality control is inconsistent

The 4.1 average comes from a visible one-star share, and the complaints cluster around hardware consistency: defective strike screws, random beeping, keypad lockout glitches, locking loops, and low-battery alerts that arrive far too early. A locksmith-style forum thread also documents an Aqara U100 failing within under two weeks of ownership, which is exactly the kind of report that a spec sheet will never show you.

Two more limits worth knowing: only gray and silver finishes, so it will not match black or brushed nickel hardware, and the lock cannot be rekeyed to match an existing deadbolt tumbler. The native Aqara app is also the weakest part of the package.

Who should buy it

Buy it if every adult in the house already carries an iPhone or Apple Watch and you have, or will add, a hub. Apple Home Key is genuinely the most satisfying unlock method we tested, and the Do Not Disturb muting keeps the chirps out of a child’s bedroom.

Skip it if you are in a mixed Android and iOS household, or if you want zero dependence on a bridge device to check whether the door is locked from the office.

6. Tapo Smart Lock DL110 – Best for Quiet Operation and a Rechargeable Battery

The DL110 solves the thing that annoys everyone about battery-powered locks: the yearly swap. Instead of AA cells it uses a removable rechargeable pack claimed to run a full year, and the same USB-C port doubles as emergency power if the pack dies completely.

It is also one of the few locks at this price with a BHMA Grade 2 certification, which is a step up from the Grade 3 parts on most of the field. The deadbolt is noticeably quiet in operation, and the supplied keys fit a Schlage SC1 keyway, so it can share a cylinder with compatible hardware.

Six ways in, and one that needs explaining

You can unlock by fingerprint, keypad code, Wi-Fi remote, close-range Bluetooth, smart home assistant, or the included backup keys. Fingerprint recognition runs in 0.42 seconds and stores up to 100 prints, and resident profiles support permanent codes alongside one-time and scheduled guest codes.

The hidden keypad is the flaw. Numbers do not appear until you touch the screen, which looks sleek in photos and slows down a guest who is not expecting it. The doorbell button tucked under the key cap is a second small annoyance, because it sends false notifications when brushed.

Battery, and the proprietary problem

Long-term owners report the pack holding around 78 percent after eight months, which matches the one-year claim better than most. The battery gauge is not precise, drifting downward by roughly 1.5 percent per week after several months, so treat it as a rough signal rather than a readout.

The catch is that the pack is proprietary, with no third-party replacement, and the codes and fingerprints have to be added to each lock individually if you install more than one. There is also no Matter support and no open API, so automation is limited to the Tapo app.

Who should buy it

Buy it for a family that hates changing batteries, on a door with an active street where a quiet deadbolt matters. Scheduled guest codes make it a good fit for short-term rental hosting where turnover is constant.

Pass if your smart home runs on HomeKit, SmartThings or anything outside TP-Link’s own app, or if you would rather not own a proprietary battery brick.

7. Philips 4200 Series WiFi Keypad Deadbolt – Best When Your Door Also Needs a Handle

Most smart deadbolts assume you already have a working handle. The Philips 4200 Series ships with a matching door lever set, so if your door has a separate pull handle, this one replaces the whole entry in a single install.

It connects directly to 2.4 GHz Wi-Fi with no hub or bridge, and the fingerprint reader unlocks in 0.3 seconds. Voice control through Alexa and Google Assistant is supported for locking and for status checks.

Code flexibility is the sleeper feature

Beyond fingerprints, the app supports permanent, one-time, periodic and recurring PIN codes. That is the set-up hosts actually want for short-term rentals and house-sitters, since a recurring code can be tied to a stay rather than a person, and a one-time code can be texted to a guest for a single visit.

Auto-lock delay is adjustable from 0 to 180 seconds in the app, but it ships switched off, so enable it yourself on day one. The back-lit keypad and anti-peeping password are both genuinely useful at night.

Watch the Wi-Fi range and the batteries

The range cap is the biggest practical limit: the lock needs to be within about 33 feet of the router, and walls or metal in between will cut that down further. Only 2.4 GHz is supported. Batteries are not included, only 1.5V alkaline cells are recommended, and owners report roughly six months from a set.

Two installation details catch people out. The lock is configured for a right-opening door as supplied and needs a reset procedure for the other handing, and overtightening the mounting screws can leave the bolt binding, which feels like a faulty lock when it is just torque.

Who should buy it

Buy it for a door that has no existing handle, or for an Airbnb or rental where recurring and one-time codes are the whole point. The included lever removes a second trip to the hardware store.

Pass if your router is far from the door, or if you need a lock you can rekey to your existing key, since this one does not offer that path.

8. Wyze Auto-Lock Bolt v2 – Best First Smart Lock for New Installers

The Bolt v2 is the one we would hand to somebody installing their first smart lock. Installation is around 12 minutes, the eight AA batteries come in the box, and the whole thing is BHMA Grade 2 rated with IP53 weather sealing.

Four unlock paths are available: fingerprint, the Wyze app, keypad code, and physical keys. The fingerprint reader sits on tempered glass and resolves in about half a second, and the AI learning scanner genuinely improves within the first week of use as it adapts to a specific finger.

Where the AI scanner earns its name

On paper every fingerprint lock claims learning. In practice this one showed the fastest accuracy gain of the group during the first week, mostly because the glass pad stays clear of grease and grime. A USB-C port accepts any power bank for emergency unlocking, which is the safety net that stops a flat battery from becoming a locksmith call.

One integration is worth calling out: paired with a Wyze Video Doorbell, you can unlock from the live camera feed, which is genuinely useful when a delivery driver is standing there holding a parcel.

The small annoyances, honestly

Keypad beeps are quiet, which is a real accessibility problem for anyone with hearing loss. Very elderly fingers or low blood flow can be hard to enroll at all, and the reader sometimes throws errors on the first attempt. The auto-lock timer has no pause, so it will re-lock a door you deliberately left open for a delivery or a party.

The design is cloud-dependent: setup and operation run through the Wyze app with no local network access, so an internet outage takes remote features offline. The mechanical key still works, which is the point.

Who should buy it

Buy it if you want a Grade 2 rated fingerprint lock with Wi-Fi included at the lower end of the connected range, and you are not replacing an existing deadbolt. It is a solid pick for a garage side door or a secondary entrance.

Skip it if anyone in the household has difficulty being enrolled by a fingerprint reader, or if you want the lock to keep working on your local network when the internet drops.

9. eufy Security FamiLock S3 Max – Best All-in-One Lock, Doorbell and Peephole Replacement

The FamiLock S3 Max is for one specific problem: you want a lock, a video doorbell and a way to check the door without a phone, and you would rather install one thing than three. It does all three, and the interior rear video screen is the feature that changes daily life for families with children or elderly parents.

Palm vein recognition unlocks in roughly 0.6 seconds by holding your hand up, and the biometric data stays on the device. The camera is a 2K unit with an f/1.8 lens covering about 150 degrees from head to toe, and it carries BHMA Grade 1 certification with a hidden, pick-resistant keyway.

Battery life is the weak point

This is where the design falls short of its own claim. Reviewers report battery life well below the stated four months, and some have seen close to one month even in battery saver mode. The emergency AAA cells are meant to add about a month, but reports of those lasting overnight do exist, and the rechargeable pack is a proprietary eufy part.

If you dislike laddering down the steps to swap a battery in the rain, factor that frustration into your decision. The dual power system helps, but it is a mitigation rather than a fix.

Ecosystem notes and physical placement

Matter and Apple Home support sit alongside eufy HomeBase 3, Google Home, Alexa and SmartThings, and 16GB of built-in storage covers the core features with no required monthly subscription. Camera streams are not available over Matter, though, and owners report intermittent drops from HomeBase 3 even while other eufy devices stay connected. HomeBase 2 is not supported.

It will not work behind a screen door, because the camera view is blocked, and the interior screen cannot be set to activate automatically on motion or the doorbell. The motor is also slow by the standards of this group.

Who should buy it

Buy it if the whole point is consolidating three devices into one, and you want the palm wave rather than a finger press. It suits a front door with a clear view of visitors and a household that values seeing who is there before opening.

Pass if battery changes are a dealbreaker, you are behind a screen door, or you want the camera to work inside a Matter automation. For straight fingerprint access without the camera weight, the eufy C220 earlier in this list is the calmer option.

10. Lockly Visage Zeno – Best for Facial Recognition

The Visage Zeno is the one to buy if the idea of touching nothing at all appeals to you. The camera recognises your face as you approach, with dual infrared sensors so it still works in the dark, and the facial data is encrypted and stored on the lock rather than in a cloud.

Everything else is familiar and good. A 3D fingerprint sensor reads in 0.2 seconds and stores up to 99 prints, Apple Home Key works with a tap, and built-in Wi-Fi handles remote control through the Lockly Home app without a bridge.

Facial recognition has a catch

You have to look directly at the camera. That is the difference between a camera that reads a passing person and a camera that requires you to stand in front of it for a beat, and for some households that delay makes the feature a gimmick rather than a convenience. Treat it as an addition to fingerprint entry, not a replacement for it.

Power comes from two 10000 mAh rechargeable batteries with a USB-C backup socket, and no published runtime figure. Since this lock also runs a camera with a 2K sensor behind it, battery expectations should be conservative.

Fit and long-term confidence

The universal fit covers right or left swing doors from 1-3/8 to 3-1/8 inch thick, and install took about 15 minutes. Unusually thick doors fall outside that range. It is also the least-reviewed lock in this group, with fewer long-term reliability reports than the more established models, which is worth weighing given how much is riding on the camera.

Who should buy it

Buy it if facial entry is a specific requirement, you have an Apple device for Home Key, and you are comfortable with a rechargeable battery and a higher outlay. The IP65 zinc body handles weather well.

Pass if you want the lowest total cost, if you need a proven multi-year track record, or if you would rather not stop and face a camera in the rain. The fingerprint locks earlier in this guide do the same job for less.

Smart Lock Buying Guide: What Actually Matters

Ten locks, ten different sets of trade-offs. These are the decisions that decide which one you will still be happy with in three years, and the questions to ask before you buy anything.

Retrofit lock or full deadbolt replacement?

A retrofit unit bolts onto the inside of an existing deadbolt and leaves the outside cylinder, the strike plate and your keys exactly as they are. A full replacement removes the whole deadbolt and installs new exterior and interior hardware, which means a new look on the front of the door and a new key.

For renters, apartments, and any door governed by an HOA, retrofit is usually the only acceptable option, and it is why retrofit locks are recommended consistently in homeowner forums. For your own front door, a full replacement is usually better because you can choose the finish, the size, and the security grade, and a locksmith can key it to your existing locks.

Our picks split roughly evenly. The TEEHO TE001, Tapo DL110, Philips 4200, Wyze Bolt v2 and the Schlage Encode are all full replacements. If you cannot touch the outside of your door, look for a retrofit design from a specialist maker, and be aware of the trade-offs: retrofit locks are often bulkier on the inside, they cannot always track the door position, and some models ask you to lift the unit off the door to change batteries rather than swapping cells.

Which unlock method fits your household?

Rank the methods by what people will actually use, not by what looks best in a demo. Keypad codes are the most reliable, cheapest and most shareable option, and every lock here has one. Fingerprint readers are fast and secure but can struggle with very dry skin, very elderly fingers or low circulation, which is the most common enrollment complaint across this whole group.

Apple Home Key and similar NFC taps are the most satisfying experience when the whole household is on the same platform, and the Aqara U100 and Lockly Visage Zeno both support it. Palm vein and facial recognition are the newest and the most impressive, and both carry the same caveat: they need a clear approach rather than a passing wave.

Always keep a physical key. Long-term users treat it as mental insurance, and it is the reason a battery failure is an inconvenience rather than a crisis.

Hubs, ecosystems and Matter explained

A hub is a small always-on device that gives a Bluetooth-only lock a path to the internet so you can control it from away. Locks with built-in Wi-Fi, like the Schlage Encode, ULTRALOQ Bolt SE, eufy C220, Philips 4200, Wyze Bolt v2 and Lockly Visage Zeno, skip that purchase entirely.

Matter is a shared standard that lets locks, lights and sensors work in Apple Home, Google Home, Alexa and SmartThings without a brand-specific bridge. It is the direction the category is moving, and it matters most if you plan to change platforms later. The catch is that Matter over Thread, the low-power mesh version, still needs a Thread border router in your home, which is extra hardware. The Aqara U100 needs an Aqara Zigbee hub, and the eufy models push you toward the eufy app rather than open standards.

Ask one question before buying: what does this lock need, beyond the box, to unlock from my phone when I am not home?

What ANSI/BHMA grades actually mean

ANSI/BHMA grades measure three things at once: resistance to forced entry, durability over cycles, and finish quality. Grade 3 is the entry level and appears on the TEEHO TE001 and eufy C220. Grade 2 is the meaningful residential standard, and the Tapo DL110, Philips 4200 and Wyze Bolt v2 carry it. Grade 1 is the top residential tier, which is where the eufy FamiLock S3 Max and the Schlage Encode sit.

A locksmith’s reality check matters here too. Consumer smart locks can be softer against a drill than a hardened steel deadbolt because of plastic housings and lighter mounting plates. The electronics are a convenience layer; the grade is what actually resists an attack, so do not upgrade a weak door to a smart one without fixing the door.

Battery life and what drains it fastest

Expect anywhere from six months on alkaline cells to a claimed year on a rechargeable pack, and up to 18 months on a low-energy Thread radio. Real numbers are usually shorter than the claim, and busy front doors drain fastest because each unlock wakes the radio and talks to the network.

Three habits extend battery life: enable auto-lock so the lock reports state instead of idling on a wide-open network connection, buy the manufacturer’s recommended cell type, and replace batteries before the low-battery alert rather than after. Every lock in this group includes a physical key or a USB-C emergency input for the day it does run flat.

Smart locks for renters, apartments and landlords

If you rent, the rule is simple: do not change the outside of the door. A retrofit unit that covers the existing cylinder is the answer, and in a rental, that is worth more than any fingerprint reader.

Getting permission takes a short written request that names the model, states that no exterior hardware changes, mentions the ANSI/BHMA grade, and offers to restore the original lock on the way out. Forum threads about this are full of the same lesson: the friction is almost always administrative, not technical. Expect some buildings to charge an application fee or a deposit, which is a property-management policy rather than a lock problem.

How to harden a smart lock against hacking

Cloud-connected door hardware attracts real concern, and the fear is reasonable. Six steps close most of it: turn on two-factor authentication if the app offers it, use a long unique Wi-Fi password on a WPA2 or WPA3 network, keep the lock’s firmware and app updated, give every guest their own time-limited code instead of sharing yours, never share the master admin account, and check the activity log when something feels off.

Add a physical layer that software cannot touch. A BHMA Grade 2 or Grade 1 rating, a solid strike plate with long screws into the door frame stud, and a deadbolt that throws fully are what actually stop an intruder.

Why is my smart lock not working? A troubleshooting order

Work down this list in order, because it moves from the most common cause to the least.

1. Check the batteries first. A lock that was last used six months ago on AA cells is the single most common failure, and the low-battery warning may have gone unnoticed while you slept through the notification. Swap the cells, not just the charge.

2. Check the app connection. A router reboot, a changed Wi-Fi password, or a moved mesh node will leave a cloud lock reporting offline while the keypad still works. Re-pair the lock in the app before assuming hardware failure.

3. Test the manual keypad. If the physical keypad opens the door, the motor and bolt are fine and the problem is connectivity or credentials. If nothing works, move to step 4.

4. Look for a jam-detection or obstruction alert. A misaligned strike plate, a door that is not closing fully, or a bolt hitting the frame will trigger a jam and stop the motor mid-throw. Check the bolt throw and screw the strike plate into the frame stud.

5. Verify the credentials. Wrong user codes, a fingerprint enrolled on a finger that has since changed, and passcodes erased by a firmware update all cause silent rejections. Re-enroll the finger and re-issue the code.

6. Check for a power or weather event. Cold snaps and moisture reduce battery voltage, and outdoor units with IP53 or IP54 ratings are not sealed forever. If a lock has become unresponsive after months outside, the motor or controller has likely failed and it is a warranty matter.

Locks we did not rank, and other formats

Some of the most talked-about smart locks on the market were not in this test set. The Nuki Smart Lock is popular in Europe for its retrofit design and clean look, but owners point out that you detach the lock or use an external battery pack to charge it instead of swapping cells. Yale, Kwikset, August, Level and Switchbot are all worth checking for your ecosystem and door, and brand reputation does not guarantee model quality, so read reviews for the exact model rather than the badge on the box.

For gates, sheds and bike storage, a smart padlock is a different format entirely and none of the deadbolts here will fit the job. Our Schlage and Kwikset guides go deeper on the brands behind two of the picks here if you want model-level comparisons.

Frequently Asked Questions

Questions we get most often are answered in detail in our Schlage smart lock guide and our Kwikset smart lock roundup, and if your door is on a wine cellar or a gated entry, our wine cellar door lock picks cover a different class of hardware entirely.

Which Smart Lock Should You Buy in 2026?

If you want keyless entry with nothing to maintain and no subscription, buy the TEEHO TE001. It has the largest review base in this group, 20 codes, a one-time guest PIN, and two working physical keys, and it will still do its job when the internet is down.

If you want a connected lock without buying a hub, the ULTRALOQ Bolt SE is the strongest balance of fingerprint access, built-in Wi-Fi and Matter support. Pick the Tapo DL110 instead if you refuse to change batteries annually, the Wyze Bolt v2 if you are installing for the first time and want everything in the box, and the Philips 4200 if your door also needs a handle.

If security certification and long-term durability lead your list, the Schlage Encode is the pick, and it keeps a real key in the cylinder as backup. For Apple households, the Aqara U100 wins on Home Key but budget for the hub, and for the all-in-one lock, camera and peephole replacement, the eufy FamiLock S3 Max does more than anything else here while draining batteries faster than it claims. If you want the newest unlock method of all, the Lockly Visage Zeno reads your face and your fingerprint in the same housing.

Whichever you choose, keep the key, confirm the bolt throws cleanly into the strike plate on day one, and check the app while you are still standing at the door.
