ABSTRACT:
A remote engine starting apparatus is for installation in a vehicle for bypassing a theft-deterring start control circuit to permit remote starting of a vehicle engine. The theft-deterring start control circuit includes: an ignition switch for receiving a designated key having a preselected resistance, a first connector coupled to the ignition switch, a resistance sensing circuit portion for preventing starting of the vehicle engine unless the preselected resistance is sensed, and a second connector coupled to the resistance sensing circuit portion. The second connector is preferably matable with the first connector. The remote engine starting apparatus includes an interface device which, in turn, includes: a housing, a bypass circuit comprising a bypass resistor and a switching relay for selectively coupling the bypass resistor to the resistance sensing circuit portion to thereby enable starting of the vehicle engine without the designated key being in the ignition switch. Third and fourth connectors are coupled to the bypass circuit and are removably mated with the first and second connectors, respectively, of the theft-deterring start control circuit to facilitate installation and removal of the interface device. A receiver is operatively connected to the bypass circuit for coupling the bypass resistor to the resistor sensing circuit portion to enable engine starting responsive to receiving the remote engine starting signal from the remote transmitter.
