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 key code, which you must keep in a safe place and should match that of your car.
Transponder Keys
Often found in newer cars, transponder keys have an RFID microchip embedded in the key that transmits a specific code to the car when it is placed in the ignition. It is designed to ensure that only the right key is able to start the engine, and to prevent theft. Contact your local dealership or locksmith for an example of this technology.
When the transponder is put into the ignition, it sends an electronic message to the chip within the engine control unit (ECU) of the vehicle. The ECU is then able to determine whether the code on the key matches its digital serial number. If it does, the ECU disables the immobilizer in order to allow the engine start. If the code does not compatible to the code, then the ECU will deny the signal and prevent the engine from starting.
They cost more than traditional metal keys but offer additional security. However car thieves have developed in the past and discovered ways to get around this anti-theft system therefore the extra cost isn't enough to dissuade them completely.
Many people ask if it is possible to copy a transponder-key yourself. The answer is yes. However, it's better to leave it up to auto locksmiths. Besides, the process can vary depending on your car's make and model.
Mechanical Keys
Many older Nissans had mechanical keys. These traditional metal keys did not feature remote functions, and were capable of unlocking the doors and the ignition cylinders of the vehicle. If your key fails or the case is damaged, a locksmith will generally replace the inside components and make a replacement that works as good as new. A reputable and certified auto locksmith can also cut a key for a lower price than the dealership.
There are a variety of kinds of mechanical keys, each of which has its own unique replacement process. Linear switches, for instance come with a linear-actuation graph. This means that, as you press the key down it will move a certain distance until it reaches the stopper or activates an internal spring. The switch will send a signal to start the car when the key is inserted into the ignition.
Intelligent keys are equipped with a chip that communicates with the computer system of the vehicle. If you lose your key, it must be replaced by a new one that is programmed to work with the vehicle. This requires a more advanced key technology that is only available through a specialized locksmith for automotive. It is more expensive than a regular key replacement at the dealership.
Key Fobs
Key fobs have been an everyday feature in the majority of cars since the mid 1990s. They allow you to unlock, lock and arm the alarm of your car with the pressing of a key. Many people believe that these systems are so secure that only someone who has your key code will be able to drive away with your car. Unfortunately, that's not always the case. With just a few steps, people who aren't terribly careful can exploit these systems.
It's possible that you need to replace your Nissan key fob's batteries if they aren't working correctly. Most key fobs have a rechargeable CR2025 or CR2032 battery, and they generally last between two and three years. Refer to the owner's guide for directions if you're uncertain about how to replace the battery.
If your key fob doesn't function because of a serious issue, you might need to replace it or program it. These issues can be more complex than simply replacing the battery, and may require assistance from an auto locksmith. Some companies specialize on replacing and repairing smart keys and can provide you with an OEM intelligent key at a lower price than the dealer. They are also able to visit you, saving you the headache of leaving your vehicle at the service center. They are available 24/7 and 7 days a week.
Remotes
There are Nissan models that have a remote keyless entry system which uses an electronic key fob to unlock your door and/or turn on the engine. Having a spare key in case you misplace yours is highly recommended.
G28CarKeys that works could save you from having to pay for a tow as well as the expense of replacing your ignition keys. Fobs emit frequencies that communicate with the computer of the vehicle to perform a series of tasks such as locking and unlocking doors and trunk release, as well as the sounding of a panic alarm.
Explore our range of Nissan key fobs and locate the right one for your specific model and year. You can also get an already-programmed key fob which is a cheaper option. Make sure you select the correct design, as several look similar and may create headaches if they're not compatible. Also, online sellers who offer a pre-programmed device typically require evidence of ownership or registration to ensure legitimacy. Be wary of websites which do not require these details and could be fraudulent.
