The circuit in the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.
