Overview
This is Yamiry's simpler keypad door knob, with a backlit keypad storing 20 user codes plus 2 backup keys for a straightforward keyless swap on a standard front door.
Unlike the brand's fingerprint handle lock, this model skips biometrics and app control entirely, so it is closer in spirit to a basic electronic knob than a full smart lock. It backs a 30-day money-back window with a 1-year warranty, and installation is rated at under 15 minutes with a screwdriver.
- 20 user codes, 2 backup keys, no app needed
- Backlit keypad, IP54 weather resistant
- Auto-lock 5 to 99 seconds, adjustable
- 30-day money back, 1-year warranty
