Transponder Keys

Transponder keys are typically found in more modern vehicles. They are equipped with an RFID microchip that transmits a unique vehicle code when the key is placed in ignition.

When the transponder is inserted into the ignition, the key transmits an information to the chip within the engine control unit (ECU) of the vehicle. The ECU checks to see if the key's code on the key corresponds to the digital serial number of the ECU. If it does, the ECU disables the immobilizer in order so that the engine can start. If the code does not matched, then the ECU will block the signal and prevent the engine from beginning.
