Every Smart Lock Compared: Compatibility, Batteries, and the Catch (2026)

By SmartHomeWorkflow Team · Last updated 2026-08-10

Smart locks are the mirror image of video doorbells: there, the catch is a monthly fee; here, every lock in our library is subscription-free: the sticker price is the whole price. What sorts this category instead is fit: whether the lock works with your ecosystem, whether it can go on a rental door, and how often you’ll feed it batteries. Every cell below renders live from the same verified records behind our compatibility checker. Facts and catches, no rankings.

Aqara Smart Lock U200 — the catch, per ecosystem ~$169.99 at time of research — never treated as a live price ✓ Amazon Alexa: works — Through Matter you get lock, unlock and status. Fingerprint, tap-to-unlock, passcode management and Aqara settings such as auto-lock live in the Aqara Home app. The lock is Thread-only, so you need an Echo or eero that acts as a Thread border router; an older Echo alone will not connect it. ✓ Google Home: works — Google turns off voice unlock for every Matter lock, and turns off remote unlock unless the lock requires a PIN, so 'Hey Google, unlock the door' does not work. You need a Google device with a Thread border router (Nest Hub 2nd gen or Nest Wifi Pro), since the lock is Thread-only. Fingerprint, tap-to-unlock and passcode management stay in the Aqara app. ✓ Apple Home: works — Joins Apple Home through Matter over Thread rather than Apple's older HomeKit route, so you need a home hub with a Thread radio: HomePod, HomePod mini or a Thread-capable Apple TV 4K. Apple Home Key works from a supported iPhone or Apple Watch. Temporary guest codes cannot be set from Apple Home, and fingerprint and tap-to-unlock management stay in the Aqara app. ✓ SmartThings: works — Needs a SmartThings hub with a Thread border router (SmartThings Station, Hub v3, Aeotec, or newer Samsung TVs), because the lock is Thread-only; a hub that only does Matter over Wi-Fi will not connect it. Through Matter you get lock, unlock and status; fingerprint, tap-to-unlock and Aqara settings stay in the Aqara app. ✓ Home Assistant: works — Works through Home Assistant's official Matter support, including managing PIN codes, but you need Home Assistant's Matter add-on plus a Thread border router on the network because the lock is Thread-only. Fingerprint and tap-to-unlock enrollment and Aqara-specific settings still need the Aqara app, and community reports say managing lock codes through Matter can be unreliable on this model. Connection: Thread · Matter · Bluetooth · Hub for full use: Yes (Needs a Thread border router in whichever ecosystem you choose. The lock has no Wi-Fi radio; everything runs over Thread. A HomePod, HomePod mini or Apple TV 4K, a Thread-capable Echo or eero, a Nest Hub (2nd gen) or Nest Wifi Pro, or a Thread-capable SmartThings hub all qualify.) · Works offline: Partly — some of it keeps working without the internet and some of it does not Full sourced profile for Aqara Smart Lock U200 →

August WiFi Smart Lock (4th gen) — the catch, per ecosystem ~$199.99 at time of research — never treated as a live price ✓ Amazon Alexa: works — Cloud-to-cloud via the August Alexa skill using the lock's built-in WiFi — lock and status by voice anytime, but voice UNLOCK requires a 4–12 digit PIN configured during skill account linking; no PIN set, no voice unlock. ✓ Google Home: works — Cloud-to-cloud Works-with-Google-Home linking using the lock's built-in WiFi. Voice unlock works but Google requires a spoken security PIN for any voice unlock — a Google platform rule for locks, not stated on August's page. ✓ Apple Home: works — HomeKit is genuinely native on the 4th gen (WiFi/Bluetooth in the lock, no bridge). Remote Siri/Home-app control away from home needs an Apple home hub (HomePod or Apple TV). No Matter support — August's own compatibility pages list no Matter or Thread anywhere (re-checked 2026-08-07, still absent). ✓ SmartThings: works — Official cloud-to-cloud linked service — SmartThings talks to August's cloud, so it needs the lock's WiFi online and there is no local execution; no SmartThings hub required. ✓ Home Assistant: works — Official integration in Home Assistant core (since 0.64, IoT class Cloud Push) covering lock/unlock, DoorSense door state, battery, and who-operated attribution — but entirely cloud-dependent on the August/Yale cloud (no local API), some data updates slowly because August offers no push API for it, and HA's docs flag Gen-4 battery reporting as frequently inaccurate. Connection: Wi-Fi · Bluetooth · Hub for full use: Yes (No bridge, and that is the 4th generation's whole point — the radio moved into the lock. August states it plainly: 'the August Wi-Fi Smart Lock requires no additional bridge to connect. Wi-Fi capability is built right into the smart lock.' Home Assistant's own documentation agrees from the other side, listing the Gen 4 among the devices that do not require a Connect Bridge or Doorbell. Worth knowing if you are comparing against the older Smart Lock + Connect, which does need one. The lock's Wi-Fi is unusually flexible for this category: 802.11 b/g/n on 2.4GHz OR 5GHz, where most smart locks are 2.4GHz-only.) · Works offline: Partly — some of it keeps working without the internet and some of it does not Full sourced profile for August WiFi Smart Lock (4th gen) →

ULTRALOQ Bolt Fingerprint (Apple Home + Wi-Fi) — the catch, per ecosystem ~$199.99 ultraloq.com listed the Bolt Fingerprint at $199.99 on 2026-08-14, read from the storefront's structured product endpoint; both Apple Home + Wi-Fi variants (satin nickel and black) carry that price with no compare-at figure, identical to the Matter-over-Thread variant. Price at time of research. ✓ Amazon Alexa: works — ULTRALOQ lists this variant as working with 'Apple Home, Amazon Alexa, Google Home, SmartThings, IFTTT'. The route is not stated — this version is not the Matter one, so the connection is ULTRALOQ's own Wi-Fi service rather than Matter, and the level rests on the manufacturer's word alone. Amazon publishes no per-model entry to check it against. ✓ Google Home: works — Named in ULTRALOQ's list for this variant. As with Alexa, the mechanism is unstated and non-Matter, so the claim rests on the manufacturer's word; no Google-side per-model listing was found. ✓ Apple Home: works — This is the version ULTRALOQ actually names Apple Home for, and it is the reason to choose it: the variant is literally titled 'Apple Home + WiFi + Bluetooth'. ⚠ ULTRALOQ does not say whether the pairing is HomeKit or Matter, and this variant is not the one covered by the Matter certificate — so 'Apple Home' here is the vendor's claim, not a certified route. As with any Apple Home accessory, remote control away from the house needs an Apple home hub: ULTRALOQ's own FAQ says 'you will need to set up an iPad, HomePod, or Apple TV as your remote control hub', which sits awkwardly beside the variant selector's 'no hub required' line. Both are true of different things — the lock needs no bridge for Wi-Fi; Apple needs a home hub for remote access. ✓ SmartThings: works — Named in ULTRALOQ's platform list for this variant. Mechanism unstated and non-Matter; no SmartThings-side listing for this model was found, so the claim rests on ULTRALOQ's word. ? Home Assistant: inconclusive — Home Assistant appears nowhere on ULTRALOQ's product page, and no ULTRALOQ statement of support or non-support was found. Unlike the Matter-over-Thread version of this same lock — which HA can commission through its official Matter integration — this variant has no certified local route to point HA at. Recorded unknown rather than none because the vendor says nothing either way.

ULTRALOQ Bolt Fingerprint (Matter over Thread) — the catch, per ecosystem ~$199.99 ultraloq.com listed the Bolt Fingerprint at $199.99 on 2026-08-14, read from the storefront's structured product endpoint; the Matter-over-Thread variant (SKU BOLT-F-MATTER) carries the same price as the Wi-Fi/Apple Home variants and no compare-at figure. Price at time of research. ✓ Amazon Alexa: works — ULTRALOQ lists this variant as working with 'Matter-compatible platforms including Apple Home, Alexa, Google Home, and Samsung SmartThings'. Everything runs over Matter-over-Thread, so the Echo in question must be a Thread border router — a plain Echo Dot gets you nothing. Alexa's standard voice-unlock code gate applies. ✓ Google Home: works — Named in ULTRALOQ's Matter platform list, over Thread only — needs a Google Thread border router (Nest Hub 2nd gen, Nest Hub Max, Nest Wifi Pro). Google disables voice unlock for Matter locks and restricts remote unlock, so expect lock and status to be the reliable operations. ✓ Apple Home: works — Reached through Matter rather than a legacy HomeKit pairing on this variant, so it needs a Thread-capable Apple home hub (HomePod, HomePod mini, or Apple TV 4K with Thread). ⚠ Do not read Apple Home Key into this: ULTRALOQ sells Home Key on its Bolt NFC line, and nothing on the Bolt Fingerprint page claims it for this model. ✓ SmartThings: works — Named by ULTRALOQ ('Samsung SmartThings') and corroborated by the Matter certificate. Requires a SmartThings hub that is a Thread border router; a hubless SmartThings app cannot commission a Thread-only device. ✓ Home Assistant: works — Home Assistant is not mentioned anywhere on ULTRALOQ's page — this level rests on the Matter certificate, not on the vendor's word. HA's official Matter integration commissions certified locks over Thread (with a Matter server and a border router such as HA's own OpenThread Border Router add-on) and exposes lock, unlock, state and PIN-credential management. Fingerprint enrolment and user management stay in the U-tec app. Connection: Thread · Matter · Bluetooth · Hub for full use: Yes (Needs a Thread border router — ULTRALOQ states it plainly for this variant ('Requires a Matter Over Thread hub controller (Thread border router)'), and the Matter certificate lists Thread as the ONLY transport. There is no Wi-Fi radio in this version to fall back on.) · Works offline: Partly — some of it keeps working without the internet and some of it does not Full sourced profile for ULTRALOQ Bolt Fingerprint (Matter over Thread) →

Aqara Smart Lock U400 — the catch, per ecosystem ~$269.99 at time of research — $269.99 read from Aqara's own storefront structured data (SKUs DTC-US-EN-U400-BLACK and DTC-US-EN-U400-SLIVER, both in stock at the same price) rather than the rendered page, per this vendor's standing method rule. ⚠ Budget beyond the lock if UWB hands-free unlocking is why you want it: Aqara requires 'a Thread-enabled Apple Home hub' for that feature, which is a HomePod or Apple TV you may not already own. Never treated as a live price. ? Amazon Alexa: inconclusive — Not established for this model. Aqara's description names Apple Home explicitly and then generalises — 'Aqara and other Matter-compatible platforms through the Aqara app' — without naming Alexa. Alexa is a Matter controller, so the lock is very likely reachable there, but 'likely' is not evidence and this catalogue does not publish protocol theory as a compatibility claim. Recorded as unknown rather than inferred. ? Google Home: inconclusive — Same position as Alexa: not named in Aqara's own description for this lock, and not inferred from the fact that it speaks Matter. An honest unknown. ✓ Apple Home: works — ⚠ THE DEEPEST APPLE STORY IN THIS CATALOGUE'S LOCK SHELF, AND THE ONE WITH THE MOST PREREQUISITES — read both halves. Aqara names Apple Home support with specific minimum versions, 'iOS 18.5+, watchOS 11.5+', and the headline feature is UWB hands-free unlocking: the door opens as you approach with your phone or watch, no tapping. But that feature is not in the box. Aqara states it needs 'a Thread-enabled Apple Home hub', and tap-to-unlock needs 'an Apple Thread-enabled Matter controller' — a HomePod or a Wi-Fi + Ethernet Apple TV 4K, bought separately; the Wi-Fi-only Apple TV 4K has no Thread radio. Without one you have a capable keypad-and-fingerprint lock and none of the hands-free behaviour it is sold on. ? SmartThings: inconclusive — Not established — Aqara's description for this lock names Apple Home and 'other Matter-compatible platforms' generically without naming SmartThings, and no per-model statement was found in either direction. ? Home Assistant: inconclusive — Not established for this model, and deliberately not borrowed from siblings: Aqara names Home Assistant explicitly on its G410 doorbell and G350 camera pages, and does NOT name it in this lock's description. The same vendor's platform lists demonstrably differ per product, so the omission stays an unknown rather than becoming either an inherited yes or an evidenced no. Connection: Thread · Matter · Bluetooth · NFC · Hub for full use: Yes (Not for the lock's basic operation — fingerprint, passcode, NFC card and physical key all work at the door with nothing else in the house. But two of the features Aqara sells it on DO require hardware you buy separately, and Aqara names them precisely: UWB hands-free unlocking needs 'a Thread-enabled Apple Home hub', and tap-to-unlock needs 'an Apple Thread-enabled Matter controller'. In practice that means a HomePod, a HomePod mini or a Thread-capable Apple TV 4K; the Wi-Fi-only Apple TV 4K has no Thread radio and does not qualify. Anything Thread-based also needs a Thread border router to reach your phone remotely, which is the same box. If the hands-free trick is the reason you are buying this lock, price that hub alongside it.) · Works offline: Not checked — we have not established whether this keeps working without the internet Full sourced profile for Aqara Smart Lock U400 →

SwitchBot Lock Ultra Vision Pro Combo — the catch, per ecosystem ~$279.99 $279.99 for the full combo (Lock Ultra + Hub Mini Matter + Keypad Vision Pro), read from SwitchBot's own store on 2026-08-08 — price at time of research, never a live price. The lock alone is $139.99, and SwitchBot sells five other configurations in between ✓ Amazon Alexa: works — Via the SwitchBot Smart skill, which needs a SwitchBot hub online — included here. Voice unlock requires a PIN code set in the Alexa app. ✓ Google Home: works — Cloud account linking to Google Home, which needs a SwitchBot hub online — included here. Voice unlock requires a PIN code set in the SwitchBot app. ◐ Apple Home: partial — Lock/unlock and Siri via Matter, and the Matter-capable hub this needs — a Hub Mini Matter — is included in this combo, so the path works out of the box. Worth knowing if you shop the cheaper configurations: the base Hub Mini does NOT qualify. No Apple Home Key — SwitchBot states its Lock products do not support it. Face, palm and fingerprint stay in the SwitchBot app. ◐ SmartThings: partial — Via Matter as a bridged secondary device, and the Matter-capable hub required for it ships in this combo. The base Hub Mini does not qualify, so a cheaper SwitchBot bundle may not reach SmartThings at all. Biometrics stay in the SwitchBot app. ✓ Home Assistant: works — Two official HA core paths: the Bluetooth-local switchbot integration (no hub, no cloud — Lock Ultra explicitly listed: lock/unlock, door state, auto-lock, calibration, battery) and the switchbot_cloud integration via a hub. Keypad biometrics are not exposed to HA. Connection: Matter · Wi-Fi · Bluetooth · Hub for full use: Yes (Included in this combo — the Hub Mini Matter that unlocks Wi-Fi remote access, Matter, Apple Home and SmartThings ships in the box) · Works offline: Not checked — we have not established whether this keeps working without the internet Full sourced profile for SwitchBot Lock Ultra Vision Pro Combo →
Kwikset Halo Select Plus Touchscreen Smart Lock✓ fully verified	$309	worksAmazon Alexa: works	worksGoogle Home: works	worksApple Home: works	worksSmartThings: works	worksHome Assistant: works	Thread · Matter · Wi-Fi	No	Partly	—
Kwikset Halo Select Plus Touchscreen Smart Lock — the catch, per ecosystem ~$309 Kwikset's own product page listed the Satin Nickel Halo Select Plus at $309.00 on 2026-08-14. Price at time of research, not a live price; Kwikset shows no compare-at figure on this listing. ✓ Amazon Alexa: works — Kwikset states 'Works with Amazon Alexa, Apple Home and Google Home. Control your lock with your voice, create helpful automations that secure your home and manage all your smart devices in one app.' The lock is Matter 1.3 certified with Wi-Fi AND Thread transports (CSA certificate CSA25931MAT47235-24), so an Echo can reach it over either — unlike the Thread-only Matter locks on this shelf, which need a Thread border router before they work at all. Transport is left unknown because which radio a given Alexa setup commissions is not stated by either party. Alexa's standard voice-unlock code gate applies. ✓ Google Home: works — Named by Kwikset alongside Alexa and Apple Home, and reachable over Matter (certificate above). Google restricts remote unlock for Matter locks and disables voice unlock; expect lock and status to behave normally and unlock to be the restricted operation. Neither party publishes a per-model capability list. ✓ Apple Home: works — The reason to buy the Plus over the plain Select: 'With NFC technology and Apple home keys, simply tap to unlock Halo Select Plus using your iPhone or Apple Watch for easy and secure access to your home.' Home Key is provisioned through Apple Home, and Kwikset names Apple Home in its works-with statement. As with every Apple Home accessory, remote access away from the house needs an Apple home hub (HomePod or Apple TV); Kwikset does not say so on this page, and it is Apple's requirement rather than Kwikset's. ✓ SmartThings: works — SmartThings is NOT named on Kwikset's page — the level rests on the Matter certificate rather than on the manufacturer's marketing. SmartThings is a Matter controller, and this lock is Matter 1.3 certified over Wi-Fi and Thread, so a current SmartThings setup can commission it and drive the standard Door Lock cluster. Anything Kwikset-specific — SmartKey, geofence auto-unlock, code scheduling beyond Matter's own model — stays in the Kwikset app. ✓ Home Assistant: works — Home Assistant is not named by Kwikset either; this too rests on the Matter certificate. HA's official Matter integration (with a Matter server) commissions certified locks and exposes lock/unlock, state and PIN-credential management. Because this lock carries a Wi-Fi Matter transport as well as Thread, an HA household does not need a Thread border router to use it — which is unusual on this shelf and is the practical reason to prefer it over Thread-only Matter locks.

Schlage Encode Plus — the catch, per ecosystem ~$329 $329 MSRP on schlage.com on 2026-08-10. The 2026-08-08 note that Schlage published no price anywhere on its own site is no longer true: the encode-plus page now carries a product-comparison widget stating '$329 MSRP' against the Schlage Encode Plus Smart WiFi Deadbolt by name. At time of research — never treated as a live price. ✓ Amazon Alexa: works — Built-in WiFi (no hub) but requires the Schlage Home app plus enabling the Alexa skill — a cloud-linked skill, not a hubless native pairing. ✓ Google Home: works — Built-in WiFi but requires the Schlage Home app and linking the Schlage service in Google Home — a cloud-linked service, not direct native pairing. ✓ Apple Home: works — Native HomeKit over Thread with Apple Home Key. Remote control, automations, and sharing Tap to Unlock require a HomePod or Apple TV set up as an Apple home hub (a HomePod or the Wi-Fi + Ethernet Apple TV 4K also provides the Thread border router; the Wi-Fi-only Apple TV 4K does not). Not a Matter device — Schlage's KB states the Encode Plus is not Matter-enabled. ✗ SmartThings: doesn't work — Schlage's own support KB states the Encode Series (including Encode Plus) is not SmartThings-compatible — the lock is WiFi-only with no Z-Wave and no Matter, so no SmartThings path exists; Schlage points SmartThings households to the Z-Wave Schlage Connect instead. ✓ Home Assistant: works — Official Schlage integration in Home Assistant core (since 2023.9), cloud-polling via Schlage's cloud API (~30-second state refresh, internet required) — the Encode Plus is an explicitly tested device with lock control, PIN-code management, auto-lock, and battery sensors.

The Level Connect cloud bridge exists as a non-Matter alternative, but it is a 1:1 bridge and cloud-dependent. ✓ Google Home: works — Matter-over-Thread needs a Google hub that is a Thread border router — Level names Nest Hub (2nd gen), Nest Hub Max, Nest Wifi, Nest Wifi Pro, and Google TV Streamer 4K. Level Connect cloud path is the non-Matter alternative (1:1, cloud-dependent). ✓ Apple Home: works — Apple Home Key needs iPhone XS+ on iOS 17.1+ or Apple Watch Series 4+ on watchOS 10.1+; remote access and automations need an Apple Home hub (HomePod mini, HomePod 2nd gen, or Apple TV 4K 3rd gen Wi-Fi+Ethernet). The lock is also Matter-certified, so a Matter path into Apple Home exists alongside the Home Key pairing. ✓ SmartThings: works — Needs SmartThings hardware that is a Thread border router — Level names the Aeotec Smart Home Hub, SmartThings Station, Hub Dongle, Hub v3, plus select 2023 Samsung TVs, monitors, soundbars, and appliances. ✓ Home Assistant: works — Local via Home Assistant's official Matter integration (Level has an official HA brand page since 2025.10); needs a Thread border router in the HA setup, and commissioning pairs over the phone's Bluetooth — community threads report initial Level-lock pairing failures.

Lockly Visage Zeno Series Facial Recognition Deadbolt — the catch, per ecosystem ~$349 Lockly listed the Visage Zeno Series deadbolt at $349.00 on 2026-08-14, read from its own storefront data; both finishes carry that price, and no crossed-out original price is recorded even though the page presents it as a 'Sale price'. Price at the time we researched it. ✓ Amazon Alexa: works — Lockly names Alexa on the product page, and on this lock it works over the built-in Wi-Fi rather than through Matter — Lockly's hub page states the fallback explicitly: 'Devices not compatible with Matter, but that support Alexa or Hey Google, can still use voice control by pairing with a hub', and this lock needs no hub because its Wi-Fi is built in. Vendor's word alone; Amazon publishes no per-model entry. ✓ Google Home: works — Named by Lockly ('Hey Google') on the same non-Matter, Wi-Fi-based route as Alexa. The Zeno Series page footnotes voice support as requiring the Wi-Fi connection. Vendor's word alone. ◐ Apple Home: partial — Lockly states 'Apple Home Key compatible — Unlock with iPhone or Apple Watch' and lists Siri among the voice options, so tap-to-unlock is claimed. What is NOT established is how much of Apple Home you get beyond it: this lock is absent from Lockly's own Matter-compatible device list, Lockly does not describe a HomeKit pairing, and no Apple-side listing for the model was found. Recorded partial because the credential is claimed and the wider platform integration is not evidenced — an Apple household should treat Home Key as the feature it is buying, not full Home-app parity. ✗ SmartThings: doesn't work — This is an evidenced no, not a silence. Lockly states the rule — 'Only Matter-compatible Lockly devices support Siri voice control and automation with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings via Matter integration' — and publishes the membership list at lockly.com/pages/matter-compatible-devices, which names the Model S, Secure Plus/Pro latches and deadbolts, Secure Lux Mortise, Flex Touch and Access Touch models, the Compact models and the Guard series, and does NOT include the Visage Zeno. Lockly's only stated route to SmartThings is Matter, and this lock is not on the Matter list. ? Home Assistant: inconclusive — Lockly names no Home Assistant support and states no non-support either. There is no Matter certification to give Home Assistant a standard route in — this lock is absent from Lockly's own Matter list — and no way to control it on your own network is documented. We record this as unknown rather than as a no because the maker says nothing in either direction, but a Home Assistant household should assume nothing here works until there is evidence.

Schlage Sense Pro — the catch, per ecosystem ~$399 at time of research — never treated as a live price. Re-verified unchanged 2026-08-08 against Schlage's own launch announcement. ✓ Amazon Alexa: works — Matter-over-Thread only (the CSA cert lists Thread as the sole Matter transport) — requires an Echo or eero that is a Thread border router; a plain Echo Dot gets no integration at all. Lock/unlock/status via Matter's Door Lock cluster, with Alexa's standard voice-unlock code gate. UWB hands-free, entrance modes, and access-code scheduling stay in the Apple Wallet/Schlage Home apps. ✓ Google Home: works — Matter-over-Thread only — requires a Google Thread border router (Nest Hub 2nd gen, Nest Hub Max, Nest Wifi Pro). Google disables voice unlock for Matter locks and disables remote unlock unless the lock mandates a PIN — expect lock/status to work, with unlock restricted (whether the Sense Pro mandates a PIN over Matter is unverified). UWB hands-free is Apple-only today; Google Wallet Aliro keys are announced, not shipping. ✓ Apple Home: works — The strongest ecosystem: Apple Home Key + UWB hands-free unlock are shipping and Apple-exclusive today — needs iPhone 11+/Apple Watch Series 6+ AND a Thread-enabled home hub (Apple TV 4K 2nd/3rd gen Wi-Fi+Ethernet, HomePod 2nd gen, HomePod mini). Apple Home control rides Matter, not a legacy HomeKit pairing; hands-free is set up in Apple Home but the three UWB entrance modes are configured in the Schlage Home app. ✓ SmartThings: works — Matter-over-Thread only — requires a SmartThings hub that is a Thread border router; hubless SmartThings app users cannot connect this lock. Lock/unlock/status/codes per Matter's Door Lock cluster. UWB hands-free is not available to SmartThings users today — Samsung Wallet Aliro keys are announced pending certification, and entrance-mode config stays in the Schlage Home app. ✓ Home Assistant: works — Needs the HA Matter integration (Matter server) plus a Thread border router (e.g., HA's OpenThread Border Router add-on or a Nest hub). HA's Matter lock support is unusually deep — set/clear lock users and PIN credentials via documented actions — but UWB hands-free, entrance modes, and Schlage-specific settings stay in the Schlage/Apple apps. Connection: Thread · Matter · Wi-Fi · UWB · Hub for full use: Yes (Needs a Thread border router in whichever ecosystem you choose — HomePod/Apple TV 4K, a Thread-capable Echo or eero, Nest Hub (2nd gen)/Nest Wifi Pro, or a Thread-capable SmartThings hub. Its WiFi radio serves only the Schlage Home app; Matter runs over Thread alone.) · Works offline: Not checked — we have not established whether this keeps working without the internet Full sourced profile for Schlage Sense Pro →

eufy FamiLock S3 Max — the catch, per ecosystem ~$399.99 at time of research, eufy's own product page structured data — $399.99 against SKU E85V0JY1, availability InStock. Never treated as a live price. ⚠ CORRECTED from $330, a $69.99 UNDERSTATEMENT, which is the direction that costs a reader more: someone budgeting from our page would have arrived $70 short. Read from the product's own schema.org Product block rather than the rendered page, because that page also prints $349.99, $299.99 and $599.98 for other eufy locks and bundles in its cross-sell. ✓ Amazon Alexa: works — Lock control + doorbell announcements ✓ Google Home: works — no catch on record ◐ Apple Home: partial — Lock control via Matter over Wi-Fi (eufy's page names Apple Home) — but video doesn't travel over Matter, so the doorbell-cam half stays in the eufy app; Apple Home sees just a lock. ◐ SmartThings: partial — eufy's product page states it integrates with SmartThings via Matter over Wi-Fi — but Matter carries lock control only; eufy's Matter FAQ notes camera streams are not supported over Matter, so the lock's video features stay in the eufy app. ◐ Home Assistant: partial — No official eufy integration covers this lock (HA core's EufyHome integration is lights/switches only) — but an official standards path exists: pair via Matter over Wi-Fi with HA's core Matter integration for lock control. Video and doorbell features don't travel over Matter and stay in the eufy app; the unofficial eufy_security community integration remains the only route to those.

The first split: retrofit or full replacement

Retrofit (renter-safe). The August WiFi lock ($199.99) and the SwitchBot Lock Ultra (sold bare, or as the $279.99 Vision Pro combo that adds the biometric keypad and the hub) replace only the inside thumbturn; the exterior keyway, and your landlord’s key, stay exactly as they are. The Aqara U200 ($169.99) plays the same trick with Matter and Apple Home Key added; its record’s catch is that fit depends on your existing deadbolt’s geometry, so measure before buying. Our renters guide covers the whole no-drilling stack.
Full replacement (owner-grade). The Schlage Encode Plus and Sense Pro, the Yale Assure Lock 2 Plus, and the eufy FamiLock S3 Max swap the entire deadbolt for new hardware. In Schlage’s case that hardware is built to the highest grade in the door-hardware standard (BHMA Grade 1). Note the Yale and the Sense Pro are key-free: no keyway at all, so their only physical fallback is an emergency-power port (covered below).
The odd one out: the Level Lock Pro ($349) is a full replacement that looks like nothing happened: the entire mechanism lives inside the door. The trade, per its record: no keypad on the lock itself, and remote access needs a Thread border router or Level’s $79 bridge.

The second split: how you actually unlock

Every lock here does phone-app unlock; the differences are at the door. Keypad codes: both Schlages, Yale, eufy. Fingerprint: Aqara, SwitchBot. Face/palm recognition: the SwitchBot (the only tri-biometric: face + palm + fingerprint) and eufy’s 0.6-second palm-vein reader. Apple Home Key tap-to-unlock: five of the eight; the full breakdown is our Home Key guide. UWB hands-free (the door unlocks as you approach, phone still in your pocket): the 2026 frontier, on the Sense Pro only.

The third split: ecosystem reach

Locks adopted Matter faster than any camera brand, so the ecosystem columns above are greener than the doorbell table’s, but the catches matter:

Apple households are spoiled here: five Home Key locks, and the Sense Pro adds UWB on top. The one caveat is that the Yale’s Apple support rides its Wi-Fi cloud rather than Matter/Thread: the tap is local, the rest isn’t. The eufy FamiLock is the weakest fit: Matter over Wi-Fi gets lock control into the Home app, but there’s no Home Key and the doorbell-cam half stays in eufy’s app.
Alexa/Google households: everything works; the SwitchBot routes through its required hub (that’s its catch: remote, Matter, and voice all need the extra box), and the Yale needs its built-in-Wi-Fi model rather than the Bluetooth-only one.
Home Assistant: the Matter locks pair locally. The August, the Yale, and the Encode Plus all ride official Home Assistant integrations — cloud-based for August and Schlage, with a local Bluetooth option on the Yale that needs its offline key extracted first. August’s record still adds the deeper caveat: it’s the most cloud-dependent lock of the set.

Batteries are the category’s real recurring cost, from 3 months (August) to ~18 months (the Yale). What happens when they die ranges from “use your existing key” (the retrofits) to “hold a 9V battery to the Yale’s terminal” or “touch a USB-C power bank to the Sense Pro.” That’s covered model-by-model in what happens when your smart lock battery dies. To match a lock to your actual setup, run it through the checker or start from the quiz.

Frequently asked questions

Do smart locks require a subscription?

Almost never — and that makes locks the opposite of cameras. All 13 locks in our library work fully without any monthly fee. The recurring cost in this category isn't money, it's maintenance: every smart lock runs on batteries you'll replace or recharge every 3–12 months depending on the model.

Can renters install a smart lock?

Yes — that's what retrofit locks are for. The August WiFi lock and SwitchBot Lock Ultra replace only the inside thumbturn, so the exterior of the door (and your landlord's key) stays untouched. The Aqara U200 is also retrofit-style, though it depends on your existing deadbolt's geometry — measure first.

Which smart locks support Matter?

Five of our eight: the Schlage Sense Pro, Aqara U200, Level Lock Pro, SwitchBot Lock Ultra (via its hub), and the eufy FamiLock S3 Max (Matter over Wi-Fi, basic controls). The notable exception is the Yale Assure Lock 2 Plus — it does Apple Home Key over Wi-Fi, not Matter. Matter carries lock/unlock and status, but each brand's signature features (biometrics, guest schedules) still live in its own app.

What's the difference between the two Schlage locks?

The Encode Plus ($329) is the established pick: hardware built to the highest grade in the door-hardware standard (BHMA Grade 1), Apple Home Key via Thread, but no Matter. The Sense Pro ($399, June 2026) adds Matter and UWB hands-free unlock — with early-adopter firmware risk its record flags plainly. Same brand, different maturity.

How long do smart lock batteries actually last?

From our verified records: 3 months (August — the category's short pole and its #1 owner complaint) up to about 18 months (the Yale Assure Lock 2 Plus's 4×AA — the longest-lived here). Most land at 6–12 months. What happens when they die is its own question — see our battery guide.
