Best Smart locks 2026: 12 Compared (16 Sources)

What are the best smart locks in 2026?

TL;DR

Top pick: Yale Assure Lock 2 Wi-Fi (~$170) — ANSI/BHMA Grade 2 pushbutton deadbolt, ~1 year on 4 AA, no subscription; note this SKU has no Apple Home Key.
Best value: Schlage Arrive (~$199) — ANSI Grade 1 / BHMA AAA commercial-grade security with built-in Wi-Fi and 250 codes.
Best budget: Wyze Auto-Lock Bolt v2 (~$79) — fingerprint plus keypad plus built-in Wi-Fi, with a USB-C power-bank rescue port.
The 2026 headline is UWB hands-free unlocking: the Aqara UWB Smart Lock U400 (~$270) and, since 29 June 2026, the Schlage Sense Pro (~$399). [src1, src8, src11]

Summary

The smart lock market in 2026 has undergone a generational shift. Ultra-Wideband (UWB) hands-free unlocking, Matter-over-Thread as a baseline connectivity standard, and advanced biometrics — 3D facial recognition and palm-vein scanning — have moved from CES demos to shipping products. After surveying recommendations from nine major review outlets and checking every spec against the manufacturers' own pages, the Yale Assure Lock 2 Wi-Fi (YRD410-WF1, ~$170) remains the best default for most people: ANSI/BHMA Grade 2, a keyed backup cylinder, roughly a year on four AA cells, and no subscription of any kind [src5, src1]. One correction that matters at checkout: this pushbutton Wi-Fi SKU does not do Apple Home Key — Home Key needs the key-free touchscreen Assure Lock 2 Plus — and because the Assure Lock 2's Wi-Fi module and Matter module share one slot, you pick built-in Wi-Fi or Matter-over-Thread, not both [src1]. For top-tier physical security, the Schlage Encode Plus (~$319) still holds the crown with BHMA AAA / ANSI Grade 1 certification, Apple Home Key and 100 access codes, while the Schlage Arrive (~$199) delivers the same commercial-grade rating with 250 codes and built-in Wi-Fi, minus Home Key and Matter [src7, src6].

The biggest change since the last revision is that UWB stopped being a single-product story. The Aqara UWB Smart Lock U400 (~$270) was the first widely available UWB lock in the US and the first to pass Aliro 1.0 certification in April 2026 [src4, src8]. On 29 June 2026 Schlage shipped the Sense Pro (~$399), its first lock with Ultra-Wideband, Matter-over-Thread, Wi-Fi and an Aliro-designed architecture; Schlage Converge measures your speed and trajectory so the bolt throws as you reach the door rather than when you are still in the driveway. It is ANSI/BHMA A156.40 Grade BAA and commercial Grade 2, runs on four AA cells, holds 250 codes — and has no keyway at all, which removes the bump/pick attack surface but also removes the classic dead-battery rescue [src11, src10].

Value has moved. PCMag's Editors' Choice Ultraloq 2026 Upgrade Bolt Fingerprint is ~$140 for a BHMA AAA, IP65, built-in-Wi-Fi fingerprint deadbolt, but buyers should know it has no numeric keypad on the lock body — entry is fingerprint, app, Apple Watch, auto-unlock, eKey or the physical key, and it runs on eight AA cells [src15, src3]. The Kwikset Halo Select has fallen to ~$224 and is the quiet battery champion: BHMA AAA with a UL 20-minute rating and 4 AA that last ~6 months on Wi-Fi but 12+ months on Matter — it is a touchscreen-and-app lock with geofence auto-unlock, not a fingerprint lock [src13]. The Level Lock Pro (~$349) remains the invisible option — BHMA AAA, tested to 250,000 cycles, one CR2 cell inside the bolt good for 9-12 months, Apple Home Key, NFC fobs and a physical key [src2, src14].

Budget and biometrics round it out. The Wyze Auto-Lock Bolt v2 (~$79) adds built-in Wi-Fi to fingerprint and keypad entry, runs eight AA cells for ~8 months, and — unusually at this price — carries a USB-C port so a power bank opens the door if the cells die [src1, src3]. The eufy Security Smart Lock FamiLock E34 (~$230) brings palm-vein recognition, ANSI/BHMA Grade 1 and a 10,000 mAh rechargeable pack (~8 months) with a 750 mAh internal reserve worth about 15 days; it reaches Apple Home, Google Home, Alexa and SmartThings through Matter, and does not advertise Apple Home Key [src3]. The Lockly Visage Zeno (~$349) uses dual-infrared 3D face unlock that works in darkness and does support Apple Home Key [src9]. Finally, renters get a real answer this edition: the Yale Approach Lock (~$141 with the Wi-Fi module and fingerprint keypad) mounts on the inside of the door over your existing single-cylinder deadbolt, so the exterior — and your landlord's key — is untouched [src16].

Best for Each Use Case

Best Overall: Yale Assure Lock 2 Wi-Fi (~$170) — Check price

Tom's Guide and SafeHome.org both name the Yale Assure Lock 2 the best smart lock for most people, and at ~$170 against a $259.99 list it is also the value leader among premium full-replacement deadbolts. The configuration linked here is the pushbutton-keypad YRD410-WF1 with the Wi-Fi module fitted: keypad codes, Yale Access app virtual keys, auto-unlock, and a keyed backup cylinder, on four AA cells for roughly a year. Two configuration facts decide whether it is right for you. First, the Assure Lock 2 is modular and the Wi-Fi module and the Matter module occupy the same slot — fitting Matter-over-Thread means giving up built-in Wi-Fi, and the Matter module is bought separately. Second, Apple Home Key is not on this SKU; it requires the key-free touchscreen Assure Lock 2 Plus. It fits 1-3/8 in to 2-1/4 in doors on a standard 2-1/8 in bore. [src5, src1]

Best for Security: Schlage Encode Plus (~$319) — Check price

The Schlage Encode Plus carries BHMA AAA and ANSI Grade 1 certification — the highest available for residential locks — meaning it withstands 250,000+ cycles and 75 foot-pound hammer blows. Built-in Wi-Fi eliminates the need for a separate hub, and Apple Home Key enables tap-to-unlock with iPhone or Apple Watch. It stores up to 100 access codes (fewer than the cheaper Arrive's 250), fits 1-3/8 in to 1-3/4 in doors on a 2-3/8 in or 2-3/4 in backset, and keeps a physical keyway as the dead-battery route. Schlage backs the mechanical parts with a lifetime warranty and the electronics for three years. [src6, src1]

Best Hands-Free UWB: Schlage Sense Pro (~$399) — Check price

Shipped 29 June 2026, the Sense Pro is Schlage's first lock with Ultra-Wideband, Matter-over-Thread and built-in Wi-Fi, and it is designed around Aliro. Schlage Converge uses UWB to calculate your speed, trajectory and motion, so the bolt retracts as you reach the door instead of when you are still on the driveway — the failure mode that made Bluetooth geofence auto-unlock unusable for most people. Apple hands-free Home Key needs an iPhone 11 or later on iOS 18.5+ (excluding SE and 16e) or an Apple Watch Series 6 or later on watchOS 11.5+; Matter pairing needs a Thread border router such as an Apple TV 4K or HomePod mini. It is ANSI/BHMA A156.40 Grade BAA and commercial Grade 2, holds 250 codes, runs on four AA cells, and has no keyway at all — which removes bump and pick attacks but also removes the traditional dead-battery rescue, so the low-battery alert is not optional. Android support via Samsung Wallet and Google Wallet is promised later in 2026. [src11, src10]

Best UWB Value / Apple Home: Aqara UWB Smart Lock U400 (~$270) — Check price

The Aqara U400 was the first widely available UWB-enabled smart lock in the US and, in April 2026, the first to pass Aliro 1.0 certification — meaning Samsung Galaxy and eventually Google Pixel owners get cross-platform Home Key parity with iPhone users. It supports Matter-over-Thread, Apple Home Key (which needs a Thread-enabled Apple hub: HomePod 2nd gen, HomePod mini, or Apple TV 4K), fingerprint, touchscreen PIN, an NFC card sold separately, and a rekeyable physical key. The removable lithium pack lasts about six months and recharges over USB-C without taking the lock offline; IP65 covers -31 F to 151 F. Aqara publishes BHMA certification but not a grade, so treat it as a technology pick rather than a maximum-impact-resistance pick. It replaces the whole deadbolt — it is not a keep-your-keys retrofit — and Aqara recommends widening a 38 mm bore to 54 mm. [src4, src8]

Best Value Full-Replacement: Schlage Arrive (~$199) — Check price

New for 2026, the Schlage Arrive delivers BHMA AAA and ANSI Grade 1 commercial-grade security at $120 less than the Encode Plus. PCWorld gave it a 4/5, praising its rubberized push-button keypad with backlit all-weather silicone buttons, direct Wi-Fi connectivity (no hub required), and support for up to 250 access codes — more than the pricier Encode Plus. The trade-off: no Apple Home Key and no Matter support, so ecosystem compatibility is limited to Alexa and Google Home. Fits 1-3/8 in to 1-3/4 in doors, 2-3/8 in or 2-3/4 in backset, physical key retained. [src7]

Best Battery Life on Matter: Kwikset Halo Select (~$224) — Check price

The Halo Select has both Wi-Fi and Matter built in and lets you choose which radio runs — and that choice is worth a factor of two in runtime: Kwikset rates the same four AA cells at up to 6 months on Wi-Fi versus over 12 months on Matter. It is BHMA AAA with a UL 20-minute rating and a Microban-coated finish, offers 250 codes, and unlocks by touchscreen PIN, the Kwikset app, geofence auto-unlock, or a standard turnkey. Correcting a common listing error: the Halo Select has no fingerprint reader — that is the Halo Touch — and Apple Home Key requires the Halo Select Plus. Street price has fallen to ~$224. [src13]

Best Fingerprint Value: Ultraloq 2026 Upgrade Bolt Fingerprint (~$140) — Check price

PCMag's Editors' Choice pick pairs a 360-degree fingerprint sensor that reads in about 0.3 seconds with built-in 2.4 GHz Wi-Fi, BHMA AAA certification and IP65 weatherproofing at a mid-range price. Access is by fingerprint, the U-home app, Apple Watch, auto-unlock, shared eKey, or the physical key — there is no numeric keypad on the lock body, so if you need to hand a house-sitter a PIN, buy the keypad-equipped U-Bolt line instead. The linked Wi-Fi SKU integrates with Alexa, Google Home, SmartThings and IFTTT; Apple Home and Matter are on the separate Matter-over-Thread variant. Eight AA cells give roughly 10 months (U-tec quotes up to a year on Wi-Fi and up to 18 months on Matter-over-Thread), and the physical key is the only dead-battery route. [src15, src3]

Best Discreet Design: Level Lock Pro (~$349) — Check price

PCWorld rated the Level Lock Pro 4.5/5 — their highest-scored smart lock — because every smart component hides inside a bolt that fits the standard deadbolt cavity, so the door looks untouched. It adds native Matter-over-Thread and built-in door-state detection over the Level Lock+, supports Apple Home Key, NFC fobs, touch-to-unlock, app control and a physical key, and carries BHMA AAA certification tested to 250,000 cycles. A single CR2 cell hidden in the bolt runs 9-12 months. Note the narrower fit window: 1-3/4 in to 2 in doors, 2-3/8 in or 2-3/4 in backset, 2-1/8 in ANSI bore — and despite the "invisible" framing this replaces your deadbolt, so it is not a landlord-proof retrofit. [src2, src14]

Best Facial Recognition: Lockly Visage Zeno (~$349) — Check price

The Lockly Visage Zeno uses dual infrared sensors for 3D facial recognition that works in complete darkness and cannot be spoofed by a photo. It unlocks within about a second, and also supports a self-learning 3D fingerprint sensor (0.2-second match, 99 prints), Apple Home Key — which keeps working when your iPhone itself is out of power — the PIN Genie shuffling keypad that defeats smudge attacks, app control over built-in Wi-Fi with no bridge, and physical keys. Facial data is encrypted and held on the lock. It has the widest door-fit range on this card at 1-3/8 in to 3-1/8 in, and two 10,000 mAh rechargeable packs last about six months. Lockly does not publish an ANSI/BHMA grade for the Visage Zeno, which is the main reason it is not the security pick. Street price has edged up to ~$349. [src9, src3]

Best Palm-Vein Biometric: eufy Security Smart Lock FamiLock E34 (~$230) — Check price

The FamiLock E34 reads the vein pattern beneath the skin of your hand — a subdermal biometric that cannot be lifted from a glass or copied from a photograph — in about 0.6 seconds, storing up to 50 people's data locally on the lock rather than in a cloud. It is ANSI/BHMA Grade 1 and IP65, adds fingerprint, keypad PIN, app and physical key, and runs a 10,000 mAh removable pack for about eight months with a 750 mAh internal reserve worth roughly 15 more days plus a USB-C emergency port. Two corrections against widely repeated claims: the E34 reaches Apple Home, Google Home, Alexa and SmartThings through Matter (which needs a Matter hub) and does not advertise Apple Home Key, and its built-in Wi-Fi means no HomeBase is required. No monthly fee. [src3, src1]

Best Retrofit for Renters: Yale Approach Lock (~$141) — Check price

This is the only pick here that leaves the outside of your door completely alone. The Approach mounts on the interior over most single-cylinder deadbolts with a screwdriver in about ten minutes, so your existing exterior hardware, your keys and your landlord's keys all keep working — the whole reason the retrofit class exists. The bundle linked here (B-YRR110-F-WF1) includes the Wi-Fi module for remote control from the Yale Access app plus a separate biometric keypad that mounts anywhere within Bluetooth range, giving fingerprint and PIN entry without drilling the door. Trade-offs are real: Yale publishes no ANSI/BHMA grade for it because the physical security is whatever your existing deadbolt already provides, there is no Apple Home Key, and the cheaper non-Wi-Fi Approach needs a Yale Connect bridge bought separately for remote access. [src16, src1]

Best Budget: Wyze Auto-Lock Bolt v2 (~$79) — Check price

The Wyze Auto-Lock Bolt v2 adds built-in Wi-Fi to the original's fingerprint and keypad entry, so remote lock/unlock no longer costs $150+. It keeps the AI-learning fingerprint scanner (sub-0.5-second reads that improve with use), an anti-peep tempered-glass touchpad, auto-lock, IP53 weather resistance and backup keys, and it is the only pick under $100 with a USB-C port that lets any power bank open the door if the eight AA cells die. The trade-offs versus premium locks are no Matter, no Apple Home Key, and BHMA Grade 2 rather than Grade 1. [src1, src3]

Head-to-Head Comparisons

Schlage Sense Pro vs Aqara UWB Smart Lock U400

The two UWB locks on the US market answer the same question at very different prices. The Sense Pro (~$399) is the incumbent-brand answer: ANSI/BHMA A156.40 Grade BAA plus commercial Grade 2, Wi-Fi and Thread/Matter simultaneously, 250 codes, lifetime mechanical warranty — but no keyway and no on-lock biometrics. The U400 (~$270) is $129 cheaper, adds a fingerprint sensor, a touchscreen keypad, NFC and a rekeyable physical key, and was Aliro-certified first, but Aqara publishes no BHMA grade and it is Thread-only for remote access, so a Thread border router is mandatory rather than optional. [src8, src10, src11]

Pick Sense Pro if: you want a published commercial security grade, Wi-Fi that works without a Thread hub, and a US brand's lifetime mechanical warranty.
Pick U400 if: you want UWB plus on-lock fingerprint and a physical key for $129 less, and you already run a Thread border router.

Yale Assure Lock 2 vs Schlage Encode Plus

Both are premium full-replacement deadbolts. The Yale wins on flexibility — a modular platform with keypad, touchscreen and key-free variants and ~1-year AA battery life — while the Encode Plus wins on raw physical security with BHMA AAA / ANSI Grade 1 (Yale is Grade 2) and on Apple support, since the Yale SKU linked here has no Home Key. With Yale at ~$170 and Encode Plus at ~$319 the ~$150 gap makes Yale the better default; Encode Plus is right when door-kick resistance and Apple Home Key on one SKU matter more than price. [src6, src1]

Pick Yale if: you want the lowest price on a name-brand Grade 2 deadbolt with a keyed backup and a year of battery.
Pick Encode Plus if: you want the highest residential security grade and Apple Home Key without buying a different variant.

Kwikset Halo Select vs Schlage Arrive

Two mid-price BHMA AAA full-replacement deadbolts within $25 of each other. The Halo Select (~$224) has Matter built in alongside Wi-Fi, which more than doubles battery life (12+ months on Matter versus ~6 on Wi-Fi) and gets it into Apple Home. The Arrive (~$199) has no Matter and no Apple Home Key, but its backlit silicone push-buttons are easier to hit with wet or gloved hands than a capacitive touchscreen, and PCWorld measured ~1 year on AA even on Wi-Fi. [src7, src13]

Pick Halo Select if: you run Matter/Apple Home or want the longest battery life on this card.
Pick Arrive if: you are Alexa/Google-only and want physical buttons that work in rain, snow and gloves.

Lockly Visage Zeno vs eufy Security Smart Lock FamiLock E34

Both are biometric-first locks with very different biometrics and very different disclosure. Visage Zeno (~$349) uses dual-infrared 3D face recognition, works in darkness, supports Apple Home Key, and fits the widest door range here (1-3/8 in to 3-1/8 in) — but Lockly publishes no ANSI/BHMA grade. FamiLock E34 (~$230) uses palm vein, which is subdermal and cannot be lifted or photographed, is ANSI/BHMA Grade 1, and costs ~$119 less — but it reaches Apple Home only via Matter and has no Home Key. [src9, src3]

Pick Visage Zeno if: you want walk-up face unlock and Apple Home Key, and a published security grade is not a requirement.
Pick FamiLock E34 if: you want a certified Grade 1 lock and the least spoofable biometric for ~$119 less.

Yale Approach vs Level Lock Pro (the "renter-friendly" confusion)

These are constantly filed together as discreet locks, but only one is renter-safe. The Yale Approach (~$141) is a genuine retrofit: it clamps to the interior of your existing single-cylinder deadbolt, changes nothing outside, and your landlord's key still works — reversible in minutes when you move out. The Level Lock Pro (~$349) looks like a plain deadbolt but replaces the deadbolt, so it is a modification to the door hardware, needs a 1-3/4 in to 2 in door, and returns nothing to the landlord unless you refit the original. Level wins on everything else: BHMA AAA, Apple Home Key, Matter-over-Thread, 9-12 months on one CR2. [src14, src16]

Pick Yale Approach if: you rent, are bound by an HOA or lease clause, or simply do not want to alter the exterior of the door.
Pick Level Lock Pro if: you own the door, want Apple Home Key and Matter, and want the lock to be invisible.

Decision Logic

If budget < $100

→ Wyze Auto-Lock Bolt v2 (~$79). Built-in Wi-Fi for remote access, fingerprint plus anti-peep keypad, BHMA Grade 2, IP53, eight AA cells for ~8 months, and a USB-C rescue port. Best smart lock under $100 by a wide margin. [src1, src3]

If user is a renter, is bound by an HOA or lease clause, or cannot alter the exterior of the door

→ Yale Approach Lock (~$141 with the Wi-Fi module and fingerprint keypad). It is the only true retrofit on this card: it mounts inside the door over most single-cylinder deadbolts, leaves the exterior and the existing keys untouched, and comes off in minutes. Do NOT route here to the Aqara U400 or the Level Lock Pro — both replace the entire deadbolt despite being commonly described as retrofits. [src16, src14]

If user prioritizes Apple HomeKit / Home Key

→ Schlage Sense Pro (~$399) for hands-free UWB Home Key with Wi-Fi and Thread. Aqara UWB Smart Lock U400 (~$270) for the same idea $129 cheaper if you already run a Thread border router. Schlage Encode Plus (~$319) for BHMA AAA tap-to-unlock. Level Lock Pro (~$349) for invisible design. Avoid the Yale Assure Lock 2 Wi-Fi, Schlage Arrive, Kwikset Halo Select and eufy FamiLock E34 SKUs on this card — none of them carries Apple Home Key. [src8, src10, src13]

If user wants the most secure physical lock

→ Schlage Encode Plus (~$319) with BHMA AAA / ANSI Grade 1 — the highest residential rating, surviving 250,000+ cycles and 75 foot-pound hammer blows, with a lifetime mechanical warranty. Schlage Arrive (~$199) has the same rating for $120 less if Apple Home Key is not needed. Kwikset Halo Select (~$224) is also BHMA AAA and adds a UL 20-minute rating. Discount any lock that does not publish a grade at all (Lockly Visage Zeno, Yale Approach). [src1, src7, src13]

If user needs remote access and smart home integration on a mid-range budget ($150-$250)

→ Yale Assure Lock 2 Wi-Fi (~$170) for a keyed Grade 2 deadbolt with a year of battery. Schlage Arrive (~$199) for ANSI Grade 1 physical security. Kwikset Halo Select (~$224) if you want Matter and the longest battery life. Ultraloq 2026 Upgrade Bolt Fingerprint (~$140) for fingerprint plus Wi-Fi at the bottom of the tier. [src1, src7, src13, src3]

If user wants hands-free unlocking without touching anything

→ Schlage Sense Pro (~$399) or Aqara UWB Smart Lock U400 (~$270) for true UWB proximity unlock that measures approach speed and direction — the only mechanism on this card that reliably beats Bluetooth geofencing, which unlocks from the driveway and is why most owners turn auto-unlock off. Lockly Visage Zeno (~$349) for dual-infrared 3D face unlock in darkness. eufy Security Smart Lock FamiLock E34 (~$230) for palm-vein as a face-free alternative. [src10, src8, src9, src3]

If user wants the longest battery life or hates changing cells

→ Kwikset Halo Select (~$224) run on Matter rather than Wi-Fi: Kwikset rates the same four AA cells at 12+ months on Matter versus ~6 months on Wi-Fi. Level Lock Pro (~$349) gets 9-12 months from a single CR2. Any Wi-Fi-first lock should be expected to need fresh cells two to three times as often as a Thread or Bluetooth lock. [src13, src14]

If the door is unusual (thicker than 1-3/4 in, non-standard bore, mortise or euro cylinder)

→ Lockly Visage Zeno (~$349) has the widest published fit at 1-3/8 in to 3-1/8 in; the Yale Assure Lock 2 Wi-Fi (~$170) covers 1-3/8 in to 2-1/4 in. Level Lock Pro needs 1-3/4 in to 2 in, so it is wrong for a standard 1-3/8 in door. If the door has a mortise lock or a euro cylinder, none of these picks fits — measure before buying rather than after. [src14, src9]

If user wants to future-proof for cross-platform Home Key (Aliro)

→ Aqara UWB Smart Lock U400 (~$270), the first Aliro 1.0-certified lock (April 2026), or the Schlage Sense Pro (~$399), built around Aliro with Samsung Wallet and Google Wallet support promised later in 2026.
