Compatibility

EcosystemSupportThe catch
Amazon AlexaWorksWorks with this ecosystem[4]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 HomeWorksWorks with this ecosystem[5]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 HomeWorksWorks with this ecosystem[6]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.
SmartThingsWorksWorks with this ecosystem[7]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 AssistantWorksWorks with this ecosystem[8]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.

Protocols: THREAD · MATTER · BLUETOOTH[1][2][11][13][19]

Needs before it works: 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.[9]

What it can do[11]

You can tell it to

  • Lock/unlock

It reports

  • Lock state

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality[2][14]

✓ Works without a subscription: Yes.

Vendor account required: Optional — there is a documented way to use it without one.[20]

No paid tier, plan or monthly fee appears anywhere in Aqara's product description or specification page for this lock (both read 2026-08-11): no cloud-key service, no guest-access plan, nothing metered. Whether the Aqara Home app makes you register an account is not settled, and we leave it unknown rather than assume it from the app's existence.

Maintenance reality[3][13]

Security updates[15]

⚠ Aqara's declared security-update support ran to June 30, 2026 (the document this comes from names no country, so which markets it legally covers is not stated) — that date has passed. It keeps working exactly as it does now, and no security flaw is known or implied here — but the manufacturer no longer has a stated obligation to issue security fixes for it.

The only published date for this lock is in Aqara's product-security policy table: security updates until 30 June 2026, a date that has already passed. That is the finding. Aqara publishes signed per-product support statements for 45 products, including hubs, cameras, sensors, switches and a pet feeder, and not one door lock. Where other Aqara products have a later signed statement that overrides the table, this lock has nothing. That does not mean the lock is insecure, and no unpatched flaw is known or claimed. It means the manufacturer's written promise to patch it has expired and has not been renewed in any document we can find. The table names no country, so we do not say which market the promise was made for.

The catch

It fits over your existing deadbolt, so your deadbolt's shape decides whether it fits. Measure first. Also worth knowing: the only security-update date Aqara publishes for this lock has already passed, and no newer promise exists in any document we could find.

Who it's for

For buyers who want fingerprint, keypad, and Apple Home Key on a mid-range Matter lock, and for renters who need a retrofit deadbolt.
