K2 Smart Deadbolt Lock
Fingerprint deadbolt with 100-fingerprint capacity
The K2 is a fingerprint keypad deadbolt built for doors where the bolt itself has to do the work. It keeps the security characteristics of a deadbolt while removing the key, opening on fingerprint, passcode, key fob, app or mechanical key. Administrator and ordinary user groups are separated, and a holiday mode suspends everyone except the administrator.
- Deadbolt mechanism with up to 100 fingerprints stored and 0.3 s recognition
- Separate administrator and ordinary user groups, 10 administrators and 50 ordinary users
- Holiday mode locks out every credential except the administrator credential
- One-time visitor passwords delete themselves automatically after use
- Delayed auto-lock configurable between 5 and 30 seconds
Suitable for: Homeowners and property managers upgrading an existing US standard deadbolt, and distributors supplying the retrofit channel.

How it compares
Choose the K2 over the K1 when you need biometric capacity and app sharing rather than codes alone; choose it over the K3 and K4 when the opening calls for a deadbolt rather than a knob or lever.
Installation and use
Check the door hole first: the K2 suits 2-1/8 inch (54 mm) holes and will not fit 38 mm holes. Replace the existing deadbolt with a screwdriver, enrol administrators before ordinary users, and switch on holiday mode before leaving a property empty.
