Abstract
A remote starting system operable with a passive anti theft security system. The passive anti theft security system includes a first coil connected to a passive anti theft controller, which is used for transmitting a first signal to a first transponder. The first transponder has a third coil and a first code. The first transponder is responsive to the first signal and transmits the first code to the first coil. The remote starting system comprises a second transponder, which has a second code and a fourth coil. The fourth coil has two terminal ends wound about the second transponder. The system further comprises a relay that selectively shorts or opens the terminal ends of the fourth coil so as to selectively enable and disable the second transponder.
