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 keycode, which you must keep safe and should match the one in your car.

Transponder Keys

Often found in newer cars transponder keys usually contain an RFID microchip embedded in the key which transmits a unique code to the car every time it is inserted into the ignition. It is designed to guard against theft by ensuring that only the right key can start the vehicle. Contact your local dealership or locksmith to see the demonstration of this technology.

When the transponder key is placed in the ignition, it transmits a signal to the chip in the vehicle's engine control unit (ECU). The ECU examines if the number on the key matches the digital serial number of the ECU. If it does, the ECU will release the immobilizer to allow the engine start. If the code isn't compatible, then the ECU will refuse to accept the signal and stop the engine from getting started.

They cost more than traditional keys, but give you extra security. However car thieves have developed in the past and discovered ways around this security measure and so the additional cost is not enough to deter them entirely.

Many people wonder if they can copy a transponder key themselves - the answer is yes but it's best to leave the job to professional auto locksmiths. In addition, the process may differ based on your vehicle's make and model.

Mechanical Keys

Many older Nissan vehicles came equipped with mechanical keys. These keys, which were made of metal, did not come with remote functions and could only be used to unlock the doors of the vehicle and the ignition cylinders. If your key fails or the case is damaged, a locksmith will generally replace the inside parts and create a replacement that functions as new. A reputable and experienced auto locksmith can also cut you keys at a cheaper cost than the dealer.

There are a variety of mechanical keys, and each has its own unique process for replacement. Linear switches, like, have a linear actuation graph. This means that when you push the switch down it will move down a certain distance until it reaches a stopper or actuates an internal spring. The switch will send a signal to start the car when the key is put into the ignition.

Intelligent keys have an embedded chip that communicates with the computer system in your vehicle. This means that when you lose your keys, it must be replaced with a brand new one that has been programmed to work with the specific vehicle. This requires more advanced key technology, which is only available through a specialist locksmith for automotive. It will cost more than a regular key replacement at the dealership.

Key Fobs

Key fobs have been an essential feature in many cars since the late 1990s. They let you unlock, lock and arm the car's alarm with a pressing of a button. Many people believe that these systems are secure enough that only someone who has your key code will be able to escape with your car. But this isn't always the case. With just a few steps, even the most sloppy of people are able to exploit these systems.
