Tap to unlock with Apple Home Key
The U300 is the first lever lock to support Matter and Apple Home Key. Tap an iPhone or Apple Watch to the lock and you're in — even when the device is flat on battery. Running on Matter over Thread, it stays fast, local and secure across the platforms you already use.
- Apple Home Key — unlock with a tap from iPhone or Apple Watch, no app to open
- Secure NFC cards — hand a copy-proof card to family, tenants or staff
- Local and reliable — Thread keeps response quick whether you're home or away
Your fingerprint is the key
A semiconductor fingerprint reader sits right in the handle, so a natural grasp opens the door in about 0.3 seconds — no fumbling for keys or reaching for a phone.
- Up to 50 fingerprints — enough for the whole household, and then some
- 160 × 160 sensor — a denser array than most smart locks, for fast, accurate reads
- FAR under 0.0001% — the wrong print almost never gets in
Everyone gets in their own way
Beyond fingerprint and Home Key, the U300 takes a touchscreen PIN, Bluetooth, an NFC card or the mechanical key — with USB-C emergency power so a flat battery never locks you out.
- Anti-peep PIN — pad extra digits before and after your real code so no one can shoulder-surf it
- Passage mode — keep the door on latch during busy spells, then switch back to auto-lock
- Mechanical override — two physical keys included, just in case
Grip, and you're home
Hands full or dashing out, a natural grasp reads your fingerprint and lets you in — indoors or out, rain or shine, on doors 35–55 mm thick.
More than a lock, in the app
Add the U300 to the Aqara Home app through an Aqara Matter controller and it becomes part of your smart home — temporary passwords for guests, a full entry log, and automations with devices like the Aqara Video Doorbell.
- Guest access — one-time or scheduled passwords, generated even when the lock is offline
- Entry logs — see who came and went, and when
- Left or right-handed — one lock fits doors that open either way
