A circuit within the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and will notify you via flashing lights and a siren.
