KUCACCI Z3 Smart Door Lock with Keypad Handle Black

Keyless entry for front doors

The KUCACCI Z3 replaces a standard knob or deadbolt with a backlit keypad handle that supports up to 20 user codes and one-time passcodes for guests or service providers. A reversible lever fits left-hand or right-hand doors and installs with a screwdriver in about 10 minutes. Two mechanical keys are included for backup entry.

Battery power and weather sealing

Four AA batteries (not included) run the lock, and a low-battery indicator warns before power runs out. If the cells die, a Type-C emergency port on the exterior accepts a power bank for temporary operation. An IP66 rating protects the electronics from rain and dust on exterior doors.

Auto-lock timing and security lockout

Automatic locking can be set between 5 and 99 seconds after the door closes, or disabled entirely for passage mode. One-touch locking engages with a two-second press of any key. After 10 consecutive failed codes the keypad disables for 3 minutes, and silent or vacation modes mute sounds or block all user codes until the master code is entered.
