ABSTRACT:
A remote-controlled door lock includes a housing provided inside with a lock base, a deadbolt, a battery base, a circuit board and an actuating device. The deadbolt is fixed with a stopper on the center portion. The locking button of a remote controller is pressed to send out a locking signal to the circuit board to start the motor of the actuating device to rotate. Synchronously, the rotating shaft of the motor actuates a rotary member to rotate together with its notch, which rotates to reach the stopper of the deadbolt and holds the stopper immovable therein, rendering the deadbolt unable to be moved inward. Thus even if the lock rods of the lock base are pried unlocked, the door lock is still impossible to be unlocked before the actuating device is driven by a remote controller to release the deadbolt, having best effect of anti-theft.
