Abstract
An anti-theft apparatus to prevent 'car jacking' includes a transmitter carried by the driver and a receiver and a switch circuit installed in the vehicle such that, when the receiver fails to detect the signal broadcast by the transmitter, the switch circuit disables the vehicle for operation. Timer circuitry is disclosed to cause the disablement only after a selected period that the broadcast signal is lost. An event detector, such as a switch circuit connected to the door light switch circuit of the vehicle, may be used to arm the disable circuit for a selected period so that disablement occurs only when the transmitter and receiver are separated beyond their communication range during a defined time interval following the occurrent of the event.
