Nissan Car Key Replacement

Transponder Keys

Transponder keys are typically used in newer cars. They come with an RFID microchip that transmits a unique car code when keys are inserted into ignition. It is designed to guard against theft by making sure that only the correct key can be used to start the vehicle. Contact your local dealership or locksmith to view the demonstration of this technology.

When the transponder keys are inserted into the ignition, it transmits an electrical signal to the chip in the vehicle's engine control unit (ECU). The ECU determines if the code on the key corresponds to the digital serial number of the ECU. If it does, then the ECU removes the immobilizer to allow the engine to start. If the code is not in line, then the ECU will refuse to accept the signal and stop the engine from beginning.
