Aqara Smart Lock U300 is a lever-style smart lock for compatible single-bore doors such as side doors, garages, offices or rooms that do not use a conventional deadbolt. It supports Matter over Thread for integration with compatible Matter ecosystems.
Matter over Thread and Apple Home Key
U300 uses Thread for Matter connectivity together with Bluetooth/NFC for supported local functions. A suitable Matter Controller and Thread Border Router are required for Apple Home, Google Home, Alexa, SmartThings or another Matter ecosystem.
Unlocking methods
- Apple Home Key on a compatible iPhone or Apple Watch.
- Fingerprint integrated into the lever handle.
- PIN on the keypad.
- NFC.
- Bluetooth/Aqara Home where supported.
- Mechanical backup key.
Passage Mode
Passage Mode can keep the door unlocked for an appropriate period, which can be useful for offices or rooms with frequent traffic. A clear re-locking procedure should be configured to avoid unintentionally leaving the door open.

- Test mechanical key and USB-C emergency power during handover.
Deployment note
U300 is intended for compatible lever-set doors. Aluminum/glass doors, gates, specialist mortise locks or different door constructions should use a lock model designed for that hardware rather than forcing U300 into an incompatible opening.
Does U300 support Apple Home Key?
Yes. Aqara documents Apple Home Key support on compatible Apple devices.
Does U300 require an Aqara Hub?
Matter-over-Thread requires a compatible Matter Controller and Thread Border Router; it does not specifically require an Aqara Zigbee Hub.
What price is used for U300 on this website?
The AQARA 2026 listed price is 6,359,000 VND with a two-year warranty.
