The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
