- IC Fob (Key Card) Unlock: Tap a registered IC Fob against the designated area on the lock's keypad. The lock supports up to 1000 IC Fobs.
- Mechanical Key: In case of emergency or battery depletion, use the physical key provided to unlock the deadbolt.
Locking Methods
- One-Touch Locking: Press the '#' key on the keypad to lock the door from the outside.
