car key replacement nissan
Replacing the Nissan key fob battery is usually a quick and simple 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 must be kept in a safe location and should match the one that came with your car.
Transponder Keys
Transponder keys are commonly found in more modern vehicles. They come with an RFID microchip that emits a unique car number when the key is placed in ignition. It is designed to ensure that only the correct key is able to start the engine and also prevent theft. Contact your local dealership or locksmith for the demonstration of this new technology.
When the transponder key is inserted in the ignition, it sends an electrical signal to the chip within the engine control unit (ECU). The ECU is then able to determine whether or not the code in the key matches its own digital serial number. If it does, the ECU will release the immobilizer to allow the engine start. If the code does not match, then the ECU will block the signal and prevent the engine from getting started.
The keys are more expensive than traditional keys made of metal, but they provide greater security. However car thieves have developed over time and found ways to circumvent this anti-theft device therefore the extra cost is not enough to dissuade them completely.
Many people are wondering if they can copy transponder keys for themselves. The answer is yes but it's best to leave it to professional auto locksmiths. The procedure can vary dependent on the make and model of your car.
Mechanical Keys
Many older Nissan automobiles came with mechanical keys. These traditional keys were not equipped with remote functions and were used to unlock the doors of the car and the ignition cylinders. If your key is damaged or breaks, the case is damaged, a locksmith will generally replace the inside parts and make a replacement that functions as new. A reputable, experienced and reputable auto locksmith should also be able to cut a new key for a much lower cost than the dealership will charge.
There are several different types of mechanical keys each with its particular method for replacement. Linear switches, for instance, have a linear actuation graph. When you press the switch down, it will move until it comes to an obstruction. The switch will send a signal to start the car when the key is put into the ignition.
Intelligent keys have a chip that communicates with the computer system of the vehicle. This means that when you lose your key, it will need to be replaced with a new one that has been programmed to work with the particular vehicle. This requires a higher level of technology in the key that is only available from an automotive locksmith who is specifically trained, and will cost you more than a standard replacement key at the dealership.
Key Fobs
Key fobs have been an everyday feature in the majority of cars since the mid 1990s. You can unlock, lock or arm your car's alarm at the push of a button. Many people believe that the systems are secure enough that only a person with access to your keycode can steal your vehicle. But this isn't always the case. In just a few easy steps, people who aren't as meticulous can exploit these systems.
If your Nissan's key fob isn't working as it should, you may require replacing the battery. The majority of key fobs utilize rechargeable CR2025 or CR2032 batteries, and they usually last about two years. If you're not sure of how to change the battery, consult the owner's manual to get advice.
If your key fob won't function due to a major issue, you may have to replace or program it. These issues could be more complex than an easy replacement of the battery and could require an auto locksmith's help. Certain locksmiths specialize in replacing and repairing smart keys, and can provide you with an OEM intelligent key for an affordable price compared to the dealership. They are also able to come to your home, preventing you from having to leave your vehicle at a service center. They are available 24 hours a day, all week.
Remotes
There are some Nissan models that come with a remote keyless entry system which uses the key fob to open your door and/or start your engine. Having a spare key in case you lose yours is highly recommended.
A functional replacement key fob will save you the cost of a tow to the dealership, as well as the pricey replacement cost for your ignition keys. Fobs emit a sound that communicates with the car's computer to complete a series of actions, including locking or unlocking the doors, activating the trunk release, or sounding the alarm for panic.

Make sure you select the correct style, since some look similar and can create headaches if they're not compatible. Additionally, online sellers that offer a pre-programmed device typically require evidence of ownership or registration to confirm the legitimacy of the product. Beware of websites which do not require these details and could be scams.
