When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to start.
