ABSTRACT:
An operator carries a portable transmitter when away from a parked vehicle. In the event of an emergency condition, the operator manually activates the portable transmitter to transmit within a prescribed area a coded signal. Vehicles located within the prescribed area have receivers installed therein. When the receivers detect the coded signal transmitted by the portable transmitter, the receivers are activated to operate vehicle devices, such as horns, in the associated vehicles to indicate an alarm condition. The ignition system of each vehicle is enabled for operation by the insertion of a transmitter in a receptacle associated with the ignition system. The removal of the transmitter from the associated receptacle disables the associated ignition system. The placement of the transmitter in a receptacle disables the transmitter and the removal of the transmitter from the associated receptacle enables the transmitter.
