PURPOSE:To improve the safety against a theft by providing a theft preventing control circuit preventing an unlocking action by an illicit unlocking tool such as a wire while allowing an unlocking action by the rotation of a key in the alert mode. CONSTITUTION:When the unlocking signal from a remote transmitting circuit 15 or the identification code by the rotating action of an IG key 13 is inputted in the alert mode, a theft preventing control circuit 11 gives the unlocking signal to a door control circuit 24, performs the unlocking action of a door locking mechanism 22, and releases the alert mode. After the unlocking action of the door locking mechanism 22 is performed, a motor 23 is immediately driven to perform the locking action of the door locking mechanism 22 as the alert action, the rotating force by an illicit unlocking tool such as a wire can be prevented, only the rotating force by the IG key 13 can allow the rotating action against the motor 23, and the safety against a theft can be improved. |
