ABSTRACT:
An electronic door locking system for an automotive vehicle with which vehicle doors can be locked, by depressing a proper push-button type switch representative of a predetermined door-locking octal digit, only when an ignition key is not left in the ignition keyhole. Therefore, it is possible to lock vehicle doors without leaving the ignition key in the keyhole, with the result that the vehicle can be prevented from being stolen by a thief when parked. The electronic door locking system according to present invention includes a device for detecting the presence of the ignition key left in the ignition keyhole and outputting a signal to inhibit a door-locking command signal from being applied to a door lock actuating solenoid, in addition to the conventional electronic door locking system.
