A circuit within the induction coil emits a signal when the transponder is inserted into an ignition barrel. The signal will be received by the chip and cause it to transmit a signal back to the car. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start.
