ABSTRACT:
An anti-car-theft system incorporating solenoid locking devices and relays for disabling or locking a plurality of critical components of an automobile (such as the ignition, the steering, the brakes, the transmission and the hood), unless and until the system is deactivated by the entry of a security code into a control unit. To deactivate the system in a preferred embodiment, the owner first unlocks the driver's door by means of a keyless remote entry device. Once inside the automobile, the owner enters his or her security code into a keypad on the control unit, which is located inside the automobile. Upon proper entry of the security code, the system enables the car components previously disabled by the relays. After the proper entry of the security code, the system also allows the owner to enable the car components that had been locked by solenoids; these components may then be enabled by further action by the owner, such as, in a preferred embodiment, the unlocking of the passenger doors by the keyless remote entry device or by the passenger-door-unlock button on the inside of the driver's door.
