Abstract
A door lock device comprises a latch mechanism, an opening lever connected to door opening handles, a lock lever connected to a door key cylinder and an inside locking button, an anti-theft mechanism being displaceable between an anti-theft position for disabling an unlocking operation of the inside locking button and a canceling position for enabling the unlocking operation of the inside locking button, a motor for displacing the anti-theft mechanism, a controller for controlling the motor, and a sensor for detecting a locking operation of the key cylinder. When the sensor continuously detects the locking operation of the key cylinder during a predetermined period, the controller puts the anti-theft mechanism into the anti-theft position by operating the motor.
