Nissan Car Key Replacement

Nissan key fob batteries are simple to replace. But first you'll need to know if your car uses an intelligent fob, push to start button or regular remote/non-transponder key.

You'll require your key code, which you should keep in a safe place and should match the one in your car.

Transponder Keys

Often found in newer cars transponder keys are typically found in newer cars. They contain an RFID microchip in the key that transmits a unique number to the car when it is put into the ignition. It is designed to ensure that only the correct key can be used to start the engine, and to prevent theft. If you'd like to find out more about how this technology works and how it works, call your local locksmith or dealership to schedule demonstrations.

When the transponder key is placed in the ignition, it transmits an indication to the chip in the engine control unit (ECU). The ECU examines if the number on the key is compatible with the serial number of the ECU. If it does then the ECU then disengages the immobilizer, allowing the engine to start. If the code isn't matched and the ECU will reject the signal and keep the engine from starting.
