Abstract
A door lock device having an anti-theft mechanism comprises a motor adapted to change a locking lever into a locking position by a normal rotation thereof in a predetermined amount, to change an anti-theft member into an anti-theft position by a continuous normal rotation thereof over the predetermined amount, and to return the anti-theft member to an anti-theft canceling position by a reverse rotation thereof. A controller has a locking operation of changing the locking lever into the locking position by using the motor, an anti-theft operation of changing the anti-theft member into the anti-theft position by using the motor, and an anti-theft canceling operation of changing the anti-theft member into the anti-theft canceling position by using the motor. If the anti-theft position of the anti-theft member is detected after performing the locking operation, the controller performs the anti-theft canceling operation.
