Nissan Car Key Replacement

When the transponder key is inserted in the ignition, it transmits an electrical signal to the chip in the engine control unit (ECU). The ECU checks to see if the key's code on the key is compatible with the serial number of the ECU. If it does, the ECU removes the immobilizer to allow the engine to start. If the code doesn't match with the ECU will refuse to accept the signal and stop the engine from beginning.
