Automotive theft-prevention system using a key pad and a remote signaling module
First Claim
1. A method for providing security to a motor vehicle having a passenger door and a driver'"'"'s door, the method comprising the steps of:
- providing a security system having a plurality of solenoid-actuated locking mechanisms for locking engagement with critical components of the motor vehicle, a plurality of relay switches for disabling particular components of the motor vehicle, a master control unit having a digital key pad, a remote signaling module having an activation button for transmitting an activation signal to the master control unit and a deactivation button for transmitting a deactivation signal to the master control unit, and means for relaying the activation and deactivation signals from the master control unit to the plurality of solenoid-actuated locking mechanisms and plurality of relay switches;
remotely transmitting the activation signal to the master control unit by depressing the activation button on the remote signaling module;
relaying the activation signal from the master control across the relaying means to the plurality of solenoid-actuated locking mechanisms and the plurality of relay switches;
urging the solenoid-actuated locking mechanisms into locking engagement with the critical components of the motor vehicle by using the activation signal;
disabling particular components of the motor vehicle by using the activation signal to disengage the relay switches;
remotely transmitting the deactivation signal to the master control unit by depressing the deactivation button once on the remote signaling module;
unlocking the driver'"'"'s door on the motor vehicle;
operating the digital key pad to enter a security code into the master control unit to deactivate the system; and
unlocking the passenger door, disengaging the solenoid-actuated locking mechanisms, and enabling the relay switches by depressing the deactivation button a second time.

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.
