  • Patent number: 5184584
    Abstract: An electrical system for bypassing the anti-theft system of a vehicle such that the engine can be started with a remote control. In particular, this is a system which allows the operator of a vehicle to start the vehicle from a remote location without having the key in the ignition and without alarming the vehicle's anti-theft device. Activation of the remote control which throws a switch, bypasses the normal key dependant ignition circuitry. A potentiometer in the bypass loop mimics the resistance pellet embedded in the ignition key, which is normally required for engaging the engine without alarming the anti-theft device. Other portions of an anti-theft system can also be bypassed if desired.
