Patent ID: 8436721

Claim:
A vehicle anti-theft and carjack disablement system, comprising: a motor vehicle comprising at least one door, an engine, and an electrical circuit in electrical communication with the engine and, comprising, a battery in electrical communication with the engine, an engine control module in electrical communication with the battery and the engine, an input connector between and in electrical communication with both the battery and the engine control module, and an output connector between and in electrical communication with both the engine control module and the engine, wherein the engine control module controls factors that permit the engine to operate and the electrical circuit being independent of the keyed ignition switch attached to the starter motor; a normally open one-way programmable safety switch physically connected to the electrical circuit, in electrical communication with the engine control module, having an open position that prevents power from being able to start the engine and a closed position that permits power to be able to start the engine, and configured to close upon receipt of a voluntary first communication signal and open upon receiving an automatic second communication signal when the engine is not running; a keypad in electrical communication with the one-way programmable safety switch and configured to transmit the voluntary first communication signal to the one-way programmable safety switch to close it and allow the engine of the vehicle to be turned on through conventional means upon the input of a predetermined sequence of symbols into the keypad; a normally closed automatic one-way security switch that (1) is in electrical communication with the door, the one-way programmable safety switch and the electrical circuit, and able to detect when the door is open or closed, (2) has an open position that prevents power from starting the engine, (3) is configured to open within a preset time interval after receipt of an automatic third communication signal that the door is opened when the one-way programmable safety switch is closed, and (4) is configured to close upon reception of a voluntary fourth communication signal from a predetermined remote source; and a first remote transmitter in electrical communication with the automatic one-way security switch and configured to be able to transmit the voluntary fourth communication signal to the automatic one-way security switch to close.
