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 must keep in a safe location and should match that of your vehicle.
nissan car keys found in modern cars, transponder keys have an RFID microchip within 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 making sure that only the right key can be used to start the vehicle. Contact your local dealer or locksmith for a demonstration of this technology.
When the transponder key is inserted into the ignition, it sends an electrical signal to the chip within the vehicle's engine control unit (ECU). The ECU examines if the number on the key corresponds to the digital serial number of the ECU. If it does then the ECU is then able to disengage the immobilizer and allows the engine to start. If the code isn't compatible with the code, the ECU will reject it and stop the engine from starting.
They cost more than traditional keys but provide added security. However, car thieves have adapted in the past and discovered ways to get around this anti-theft system therefore the extra cost isn't enough to stop them completely.
Many people are wondering if they can copy a transponder key at home - the answer is yes but it's better to leave it to a professional auto locksmith. In addition, the process may vary depending on your car's model and make.
Mechanical Keys
Many older Nissan cars came with mechanical keys. These traditional keys did not have remote functions and were only used to open the doors of the car and the ignition cylinders. A locksmith can replace the inner components of a damaged key or a damaged case and make a replacement that works just like the original. A licensed and reputable auto locksmith can also cut you a key for a lower price than the dealership.
There are several different types of mechanical keys and each one has its unique method of replacement. Linear switches for instance have a linear actuation graph. This means that as you push the switch down it will move a certain distance until it reaches an obstruction or triggers an internal spring. The switch will send a signal to start the car once the key is put into the ignition.
Intelligent keys have an electronic chip that communicates with the computer system of the vehicle. When you lose your key it will have to be replaced with a fresh key that is programmed for the vehicle. This requires a higher degree of key technology that is only available from an automotive locksmith that is specialized, and will cost you more than a regular replacement key at the dealership.
