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 need your key code, which you must keep in a safe location and should match the one in your vehicle.

Transponder Keys

Commonly found in newer vehicles, transponder keys come with an RFID microchip inside the key that transmits a unique number to the car every time it is inserted into the ignition. It is designed to guard against theft by ensuring that only the proper key can start the vehicle. Contact your local dealership or locksmith to view an example of this technology.

When the transponder key is inserted in the ignition, it transmits a signal to the chip in the engine control unit (ECU). The ECU checks if the code on the key matches the serial number digital of the ECU. If it does it, the ECU will then release the immobilizer and allows the engine to begin. If the code isn't match, then the ECU will deny the signal and prevent the engine from starting.

They are more expensive than traditional metal keys but provide added security. However, car thieves have adapted in the past and discovered ways around this anti-theft measure, so the extra cost isn't enough to keep them from doing anything.

Many people wonder if is possible to copy the transponder-key by themselves. The answer is yes. However, it's best to leave it to auto locksmiths. Additionally, the process could vary depending on your car's model and make.

Mechanical Keys

If the key you have is damaged or broken, the case is damaged, a locksmith can typically replace the internal parts and make a replacement that functions as new. A reputable and certified auto locksmith will also be able to make a new key at a much lower price than the dealership will charge.

There are several types of mechanical keys that each have its own unique replacement method. Linear switches, for example come with a linear-actuation graph. When you press the switch down it will move until it hits an obstruction. When the key is put into the ignition the switch will send an alert to the car to start it up.

Intelligent keys contain the chip that connects to the computer system of the vehicle. This means that if you lose your key it must be replaced with a new one that has been programmed to work with your particular vehicle. This requires a higher level of technology in the key that is only available through an automotive locksmith who is specifically trained, and will cost you more than a regular replacement key would at the dealership.
