Abstract:
A vehicle starting system comprising a remote starting system that is co-operable with a passive anti theft security system, wherein the security system comprises a first coil connected to a passive anti theft security system controller for transmitting a first signal to a first transponder having a third coil and a first code therein, said first transponder being responsive to said first signal to transmit said first code to said first coil, and wherein the remote starting system comprises:(a) a second selectively operable transponder having a second code and a fourth coil with two terminal ends, said fourth coil being wound about said second transponder; and (b) a relay that shorts said terminal ends of said fourth coil to disable said second transponder and prevent transmission of said second code to said controller when said passive anti-theft security system is in operation, and that selectively opens said terminal ends of said fourth coil to enable said second transponder and allow transmission of said second code to said controller when said remote starting system is in operation.
