The key and the chip are connected by a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This generates a signal, which is received by the coil before being sent to the key identification number. The key's identification number is returned to the car and the engine is started if the identification number matches.
