Overview
Not a fingerprint or face unlock lock, the Aqara deadbolt is a keypad and Wi-Fi model you control from a phone or voice assistant. Punch in a code, share temporary passwords with guests, and lock remotely without any bridge.
Owners get remote control and voice support without buying a hub, plus anti peep codes that hide your real number. There is no biometric unlock, and AA batteries need regular replacement.
Who it's for
Families sharing codes with sitters and guests will use offline passwords and the app. Households wanting biometric entry need a different lock.
Pros and cons
- Wi-Fi without a bridge
- Anti-peep code entry
- Offline shareable passwords
- Emergency USB-C power
- No fingerprint reader
- Only supports 2.4GHz Wi-Fi
- Battery swaps about twice a year
Performance notes
Remote control depends on a strong Wi-Fi signal on the lower band at the door. Battery life depends on how often the lock connects and operates, and the emergency port bridges a dead battery. Matter features need a compatible hub.
