When the transponder is inserted in the ignition, it sends an information to the chip within the engine control unit (ECU) of the vehicle. The ECU examines if the number on the key is compatible with the serial number of the ECU. If it does, then the ECU will release the immobilizer to allow the engine to start. If the code is not compatible, then the ECU will reject the signal and keep the engine from starting.
