    摘要： The system is an electric control circuit and associated components including a door locking circuit and an ignition circuit. The ignition circuit is connected to the vehicle battery power through a latch circuit. The latch circuit has alternative "lock" and "unlock" modes for, respectively, connecting battery power to and disconnecting battery power from the ignition circuit. A code sensing circuit provides switching for the latch circuit. This circuit includes means for programming a preselected unlocking code. The code sensing circuit includes code inputting means which might be a push button pad, a barcode reader, an optical binary-code reader, or a magnetic reader; the inputting means being mounted on an entry door of the vehicle. The code sensing circuit includes comparator means for comparing the inputted code to the preprogrammed code for the sending of an unlocking signal to the latch circuit. The control circuit includes an alarm circuit, effective in the "lock" mode of the latch circuit to effect the sounding of the vehicle warning horns when battery power is connected to the motor ignition coil by external means. The ignition circuit includes manual switches for engine starting and stopping and for power to accessories. The locking circuit includes interior switches for selectively locking and unlocking entry doors and the trunk lid.
