Nissan Car Key Replacement

Replacing the Nissan key fob battery is usually 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.

You'll also need your key code, which should be stored in a secure location and should match with the one that came with your vehicle.

Transponder Keys

Transponder keys can be found in newer vehicles. They feature 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 ensuring that only the proper key can start the vehicle. If you'd like to find out more about the technology's working and how it works, call your local locksmith or dealership for demonstrations.

When the transponder key is inserted into the ignition, it transmits an electronic signal to the chip inside the vehicle's engine control unit (ECU). The ECU then examines whether or not the number in the key is in line with its digital serial number. If it does, then the ECU disengages the immobilizer to allow the engine start. If the code isn't compatible then the ECU will refuse to accept it and stop the engine from beginning.

They're more expensive than traditional metal ones, but they are safer. The cost of these keys is higher than traditional keys made of metal but they offer greater security.

Many people are wondering if they can copy transponder keys by themselves. The answer is yes however, it is best to leave it to a professional auto locksmith. The process can also vary depending on the make and model of your vehicle.

Mechanical Keys

These keys, which were made of metal, were not equipped with remote functions and could only be used to open the doors of the vehicle and the ignition cylinders. If your key breaks or the case is damaged, a locksmith can usually repair the internal components and make a replacement that works like new. A reputable and experienced auto locksmith can also cut the key at a less cost than a dealership.

There are various types of mechanical keys each with its own unique replacement procedure. Linear switches for instance, have a linear actuation graph. This means that as you push the button down, it will move a certain distance until it reaches a stopper or actuates an internal spring. When the key is put into the ignition the switch will send an electronic signal to the car to start it up.

Intelligent keys have a chip in them that communicates with the computer system of the vehicle. When you lose your key it will need to be replaced with a brand new one that has been programmed to work with the vehicle. This requires a higher degree of key technology that is only available from a specialized automotive locksmith, and will cost you more than a regular replacement key would at the dealership.
