Nissan Car Key Replacement
Replacing a 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 require your key code which should be stored in a secure location and must match the one that came with your car.

Transponder Keys
Most often found in modern cars, transponder keys have an RFID microchip embedded in the key that transmits a unique code to the car when it is placed in the ignition. It is designed to prevent theft by ensuring that only the right key is able to start the car. Contact your local dealership or locksmith to see the demonstration of this new technology.
When the transponder is put in the ignition, it sends a message to the chip that is inside the engine control unit (ECU) of the vehicle. The ECU examines if the number on the key is compatible with the serial number of the ECU. If it does, the ECU disables the immobilizer in order to allow the engine start. If the code is not in line to the code, then the ECU will block the signal and prevent the engine from beginning.
The keys are more expensive than traditional keys, but give you extra security. However car thieves have evolved in the past and discovered ways around this anti-theft measure and so the additional cost is not enough to deter them entirely.
Many people wonder if is possible to copy the transponder keys yourself. The answer is yes. However, it's best to leave it to auto locksmiths. The process can also vary depending on the brand and model of your vehicle.
Mechanical Keys
A lot of older Nissans had mechanical keys. The traditional keys made of metal did not come with remote functions and could only be used to unlock the doors of the car and the ignition cylinders. Locksmiths can replace the inner components of a damaged key or damaged case to create a replacement key that functions exactly like new. A reputable and qualified auto locksmith should also be able to cut you a new key for a much lower cost than the dealership charge.
There are several different types of mechanical keys, and each has its particular method for replacement. Linear switches, for instance come with a linear-actuation graph. This means that as you push the key down it will move down a certain distance until it reaches the stopper or triggers an internal spring. When the key is inserted into the ignition the switch will send an electronic signal to the car to start it up.
Intelligent keys are equipped with a chip inside them that communicates with the computer system of the vehicle. If you lose your keys, it will need to be replaced by a new one that has been programmed to work with the vehicle. This requires a more advanced key technology, only accessible through a specialized locksmith for cars. It is more expensive than a typical key replacement at the dealership.
Key Fobs
Key fobs have become an integral part of many cars since the latter part of the 1990s. You can unlock, lock or arm your car's alarm with the click of a switch. Many people believe that these systems are so secure that only someone with your key code can take off with your car. However, that's rarely the situation. It's possible for less scrupulous individuals to make use of these systems in a few easy steps.
You may need to replace your Nissan key fob's battery in case it's not functioning properly. Most key fobs have a rechargeable CR2025 or CR2032 battery, and usually last about two years. Consult https://www.thekeylab.co.uk/nissan-car-keys/ for directions if you're not sure how to change the battery.
If your key fob doesn't work because of a more serious problem, it may need to be replaced or programmed. These issues can be more complicated than replacing the battery and could require assistance from an auto locksmith. Some companies specialize on repair and replacement of intelligent keys, and can provide you with a OEM intelligent key for a lower cost than the dealer. They are also able to visit you, saving you the hassle of having to leave your vehicle in an auto repair shop. They are open 24/7 seven days a week.
Remotes
Certain Nissan models come with a remote keyless system that makes use of a keyfob to unlock the doors and/or start your engine. A spare key in case you misplace yours is highly recommended.
A working replacement fob for your key can save you the expense of an extra trip to the dealership and the pricey replacement cost for your ignition keys. Fobs emit a signal that communicates with the computer in the vehicle to complete a sequence of tasks, such as locking or unlocking the doors and activating the trunk release, or triggering the alarm that sounds the panic alarm.
