It is designed to ensure that only the right key can be used to start the engine, and to prevent theft. Contact your local dealer or locksmith for an example of this technology.

When the transponder key is placed in the ignition, it transmits a signal to the chip in the engine control unit (ECU). The ECU then checks to see whether or not the number in the key matches with its own digital serial number. If it does, then the ECU removes the immobilizer to allow the engine start. If the code isn't compatible, the ECU will reject it and stop the engine from beginning.
