ABSTRACT:
A security system for a vehicle having an engine compartment covered by a hood, and an ignition switch for operating the engine, includes a common housing for protecting a hood lock and an ignition lock switch. An electric circuit is provided for shorting an ignition coil during periods of non-use of the vehicle to prevent theft of the vehicle, the circuit being disarmed by the lock switch for a sufficient interval of time to permit use of the ignition switch for starting the engine. A lock-up feature within the circuit maintains the circuit in the disarmed state during operation of the vehicle, and automatically rearms the circuit upon retrieval of the ignition key.
