Nissan Car Key Replacement
Replacing the Nissan key fob battery is generally an easy and straightforward 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 require the key code that should be kept in a safe location and should match with the one that came with your car.
Transponder Keys
Transponder keys can be used in newer cars. They feature an RFID microchip that transmits a unique car code when keys are inserted into the ignition. It is designed to stop theft by ensuring that only the right key can start the vehicle. If you want to know more about the technology's working call your local locksmith or dealer to schedule demonstrations.
When the transponder is inserted in the ignition, the key transmits a message to the chip that is inside the engine control unit (ECU) of the vehicle. The ECU will then check to see whether or not the number in the key matches with its own digital serial number. If it does then the ECU removes the immobilizer, allowing the engine to start. If the code is not matched with the ECU will reject the signal and keep the engine from beginning.
The keys are more expensive than the traditional metal keys, however, they are more secure. The cost of these keys is higher than traditional keys made of metal, but they provide more security.
G28 ask if they can copy a transponder key for themselves. The answer is yes but it's best to leave it to professional auto locksmiths. In addition, the process may vary based on the vehicle's model and make.
Mechanical Keys
Many older Nissans came with mechanical keys. These keys were made of metal and did not have remote functions, and were only able to unlock the doors and the ignition cylinders of the vehicle. If the key you have is damaged or broken, the case is damaged, a locksmith will generally replace the inside parts and make a new one that functions as new. A reputable and experienced auto locksmith can also cut a key for a lower cost than a dealership.
There are several kinds of mechanical keys, each of which has its own unique replacement procedure. Linear switches, for example come with a linear-actuation graph. This means that, as you push the switch down, it will move a certain distance until it hits a stopper or actuates an internal spring. When the key is pushed into the ignition the switch will send an indication to the car to start it up.
Intelligent keys contain chips that communicate with the computer system of the vehicle. If you lose your keys, it will need to be replaced with a fresh one that has been programmed to work with the vehicle. This requires a more advanced key technology, only available through a specialist locksmith for automotive. It will cost more than a standard key replacement at the dealership.
Key Fobs

Many people believe that these systems are so secure that only a person with your key code could drive away with your car. Unfortunately, this is not always the case. It is possible for less cautious individuals to make use of these systems with the simplest of steps.

Remotes

A working replacement key fob could save you the expense of an expensive tow to the dealer, as well as the pricey replacement cost for the ignition keys that you lost.
