Abstract: A solid state computer circuit system is provided that senses the state of the ignition switch, setting a lock out circuit to prevent the car from being started if a hidden switch (or other enabling circuit) is not activated. There is a solid state timing circuit locking out the ignition system automatically after a predetermined time when the ignition switch is turned off (typically thirty seconds). The system is actuated with a hidden switch (or an electronic device like a garage door opener or a digital key pad with an alarm circuit sounding an alarm if the wrong code is input or a foreign item is used in an effort to wrongfully enable the basic system circuit).
