A smart lock turns your front door into something you never have to think about again: no fumbling for keys, no spare under the mat, no wondering whether you locked up. But the cheap ones can leave you stranded when the batteries die or the app loses its connection. We analyzed thousands of verified buyer reviews, recent sales data, and expert evaluations to find six smart locks that open the way you want and stay reliable through everyday use.

Our Best Overall pick: a complete front-door hardware swap from a household name, with fingerprint, PIN, app and key entry plus two solid lever handles, at a strong price-to-feature balance. Geeky Gadgets measured the fingerprint reader at 0.3 seconds with a 99% recognition rate.
A complete matte-black deadbolt-and-lever kit with the Wi-Fi gateway already in the box, so remote locking, code sharing and Alexa/Google voice control all work from day one. Batteries included.
Our Best Weatherproof pick: five ways in (fingerprint, keypad code, app, card fob or traditional key) plus the longest documented battery life and a USB emergency power port. The weather-sealed zinc-alloy deadbolt carries an IP45 rating and runs 12-18 months on four AA batteries.
The 4000-series configuration TechHive tested, bundled with the Wi-Fi bridge - a fingerprint touchscreen deadbolt that keeps your existing handle and adds remote control for about $106, less than either Philips handle-set kit in this comparison.
The all-in-one splurge: a palm-vein reader, a 2K video doorbell camera and a rear screen built into one deadbolt, with Wi-Fi and Matter support. Reviewers like the concept but flag a big, costly unit with palm reads that are not always consistent.
Our Best Affordable pick: a standalone fingerprint-and-keypad handle set with no app, gateway or subscription to manage - just a 500 DPI sensor, a backlit keypad and two backup keys, at the lowest price in this comparison. Veise rates it IP54 weatherproof and ANSI Grade 3 certified, and a full two-lever handle set ships in the box.
Short on time? These three cover most buyers: our Best Overall pick, a complete Philips handle set with brand-name biometrics at a strong price-to-feature balance; the lowest-priced way into a full handle-set swap, a standalone fingerprint-and-keypad kit with no app or subscription; and our Best Weatherproof pick, a five-way deadbolt sealed to IP45 with the longest documented battery life here.
Understand the category before you buy - what the science actually says, and which specs matter.
Every smart lock promises keyless entry, but how it connects to your phone and your home shapes the experience more than the number of unlock methods on the box. Here is how these locks work, why connectivity drives everything else, and the features worth comparing.
A smart lock replaces or augments your deadbolt with a motorized mechanism you control without a traditional key. It gives you several ways in and manages access from your phone.
Most shoppers count the unlock methods and stop there. The choice that shapes daily life is how the lock talks to you and your home, because each connection type makes a different trade.
Bluetooth is short-range: the lock talks directly to your phone when you are close, which is fast and easy on the batteries, but you cannot control the door once you leave. Wi-Fi is the opposite. It lets you lock up and see the door's status from anywhere, which makes remote guest access and auto-unlock possible, but that always-on radio drains batteries faster. Many locks split the difference, pairing Bluetooth for close range with a Wi-Fi gateway for remote control.
That distinction runs right through this lineup. The entry Philips handle set ships as Bluetooth and gains remote features only when you add its Wi-Fi bridge, about $40, while the Philips Wi-Fi handle set and the Philips Wi-Fi deadbolt both include their gateway in the box so remote control works from the first setup. At the other end, the Veise KS02B skips connectivity entirely and works only by hand at the door, and the Wyze bolt is Bluetooth-only with no gateway option at all. If you want to tie the lock into a smart home or control it while away, connectivity, not the fingerprint reader, is the spec to sort on first.
Once you have settled the connection, a few features decide which lock fits your door and routine:

Our Best Overall pick. The Philips 4000 Series handle set is a complete deadbolt-and-handle replacement kit with two lever heights to suit different doors, at a competitive full-kit price. The 4000-series platform underneath has strong expert validation - TechHive called its Bluetooth setup painless and had the lock running in minutes, while Geeky Gadgets clocked the fingerprint reader at 0.3 seconds with a 99% recognition rate. It stores 50 fingerprints and 100 PIN codes plus unlimited one-time codes, secures traffic with AES 128 encryption, and Philips rates the platform ANSI Grade 2 - the residential standard that covers most homes. Door-sensor auto-locking re-secures the deadbolt behind you, and it earns our Best Overall ribbon on the strength of that security, feature set and price balance at about $120 after Prime-exclusive pricing. The one thing to add on: remote access and voice control need Philips' Wi-Fi gateway, sold separately for about $40 - if you'd rather have that bundled in from the start, the Wi-Fi version of this same Philips platform, elsewhere in this lineup, includes the gateway already for a bit more money.
The Wi-Fi handle set pairs a full hardware replacement with none of the usual remote-access asterisks: the gateway, the lever handles and even the four AA batteries all ship in the box, so there's nothing extra to buy before you can lock, unlock or issue codes from anywhere. Once the bridge is on your 2.4GHz network, the Home Access app handles remote control, code management and access logs, and Alexa or Google Assistant voice commands work immediately. The underlying hardware carries the strongest expert validation in this comparison - TechHive called setup painless and had the lock running in minutes, while Geeky Gadgets clocked the fingerprint reader at 0.3 seconds with a 99% recognition rate. It stores 50 fingerprints and 100 PIN codes plus unlimited one-time codes, secures traffic with AES 128 encryption, and Philips rates the platform ANSI Grade 2. A 25% Prime-exclusive discount brought it to about $150 at our last scan for a complete kit that would otherwise require buying a gateway separately.
Our Best Weatherproof pick. The LOCKSTAR nails the fundamentals that matter most at the front door: five entry methods (fingerprint touch ID, keypad code, app, card fob and a traditional backup key), a zinc-alloy housing with IP45 sealing rated for direct rain and sun - the best-documented water rating of any lock currently in this comparison - and the best battery economy in this comparison - the brand documents 12-18 months of typical use from four AA alkalines, roughly double what Philips quotes for its 4000 series. Reviewers at Gadget Gallery timed a typical installation at 20-30 minutes with just a screwdriver and noted the deadbolt throws a full inch for solid forced-entry resistance. If the batteries ever die at the door, a USB emergency port lets you power it from any power bank, and a low-voltage app alert warns you well before that happens. It slots into Alexa and Google smart homes, and at $149 it was the only lock in this lineup priced at list at our last scan - the rest lean on discounts. It stands out in this comparison for weather sealing, battery life and fail-safe design, no handle-set commitment required.
The Wi-Fi deadbolt is the most affordable way onto the Philips platform with remote access already included: a fingerprint-and-touchscreen deadbolt that swaps in above your existing handle, plus the Wi-Fi bridge in the box. It is effectively the configuration TechHive reviewed - the tester praised the painless, minutes-long Bluetooth setup and the flexible PIN system that accepts 4 to 10 digit codes - with the gateway bundled so lock status, remote unlocking and code management work from anywhere. You still get the series' core security package: 50 fingerprint slots, door-sensor auto-lock, AES 128 encryption, a physical keyway backup and Philips' 2-year warranty. At about $106 at our last scan, it costs less than either Philips handle-set kit here and keeps your existing hardware - the sensible choice when your door handle is staying put and remote access matters, though the Veise KS02B handle set elsewhere in this lineup undercuts it further for buyers open to a full hardware swap.
The FamiLock S3 Max is the most ambitious lock in this comparison: eufy packs a palm-vein reader that unlocks the door when you hold your hand a few inches above it, a 2K camera that doubles as a video doorbell, and a rear screen into a single replacement deadbolt. It stores up to 50 palm scans and 100 PIN codes, adds app, voice and key entry, and connects over Wi-Fi with Matter support, though Matter does not expose the palm or video features. Reviewers at PCWorld and How-To Geek praise the way it replaces both a lock and a doorbell camera, with local motion-event storage and no subscription required, and installation is quoted at about 20 minutes. The trade-offs are just as consistent: it is large and far pricier than a standard deadbolt, palm recognition can be inconsistent, and some owners report the unit dropping offline. A rechargeable 15,000 mAh battery lasts several months between charges, with AAA cells as backup, and it is rated IP65 for outdoor use.
The KS02B earns our Best Affordable ribbon as Veise's no-frills answer for buyers who want biometric convenience without an app, gateway or Wi-Fi connection to maintain: everything runs locally off a 500 DPI fingerprint sensor that identifies a registered print in about 0.3 seconds and releases the deadbolt in roughly a second. It stores 20 fingerprints, 20 PIN codes and issues one-time passcodes that auto-expire after a single use, with an anti-peeping mode that pads your real code with extra digits so a shoulder-surfer learns nothing useful. The kit replaces both the deadbolt and the handle with a matched matte-black two-lever set, and Veise backs the aluminum-and-zinc build with an ANSI Grade 3 security certification and an IP54 weatherproof rating good down to -31°F. Auto-lock is adjustable from 10 to 90 seconds, a one-touch lock button re-secures the door on the way out, and a red low-battery warning lights up at 15% remaining so the four AA batteries never die without notice. At about $70 after its 22% discount at our last scan, it undercuts every other handle set in this comparison, though the tradeoff for that price and simplicity is no remote access - there is no app, Wi-Fi or Bluetooth connectivity here at all.
