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 also require your key code, which must be stored in a secure location and should match with the one that came with your car.

Transponder Keys

Transponder keys are typically used in newer cars. They have an RFID microchip that sends a unique code for the car when the key is inserted into ignition. The idea behind this technology is to prevent theft by making sure that only the correct key is able to start the car. If you want to know more about the technology's working and how it works, call your local locksmith or dealer for an explanation.

When the transponder key is placed in the ignition, it sends an indication to the chip within the vehicle's engine control unit (ECU). The ECU will then check to see whether the code on the key is in line with its digital serial number. If it does, the ECU removes the immobilizer, allowing the engine to begin. If the code doesn't matched, then the ECU will reject the signal and keep the engine from beginning.

They are more expensive than the traditional metal keys, however, they are more secure. However car thieves have developed over time and have found ways to circumvent this anti-theft device and so the additional cost is not enough to keep them from doing anything.

Intelligent keys contain a chip inside them that communicates with the computer system of the vehicle. If you lose your keys, it will have to be replaced with a fresh one programmed to work for the vehicle.
