A circuit board with an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This produces a signal which gets amplified by the coil which sends it to the key's identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will start.
