<p>PURPOSE:To make an identification code modifiable without interrupting a computer power source under the specified conditions even at a time when a key is inserted into an ignition key cylinder. CONSTITUTION:A computer 1 comprises a normal operation mode, collating the inputted ID code and operating a locking-unlocking mechanism of a vehicle door, and an ID code processing mode registering the ID code and the like. A power supply suspension circuit 2 suspends any power supply to the computer 1 at the time of closing a switch 23 detecting the insertion of a key into an ignition key cylinder which is able to identify a vehicle owner. Likewise, the computer 1 prohibits any operation of the power supply suspension circuit 2 according to a condition of specified time operations or the like of a door lock device while it comprises a mode selector part operating the ID code processing mode instead of the normal operation mode, thereby performing a modification of the ID code as checking the key insertion into the key cylinder.</p> |
