Nissan Car Key Replacement
Replacing the Nissan key fob battery is generally an easy and quick process. But first you'll need to know if your car uses an intelligent fob, push to start button or regular remote/non-transponder key.

Transponder Keys
Transponder keys can be found in more modern vehicles. They have an RFID microchip that emits a unique car number when the key is inserted into the ignition. It is designed to ensure that only the correct key can start the engine, and to prevent theft. Contact your local dealer or locksmith to see the demonstration of this technology.
When the transponder key is inserted into the ignition, it sends an indication to the chip within the vehicle's engine control unit (ECU).

If the code does not match, the ECU will reject it and prevent the engine from beginning.
