Nissan Car Key Replacement

Nissan key fob batteries are easy 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 need your key code, which you must keep in a safe place and should match that of your vehicle.

Transponder Keys

Most often found in modern cars, transponder keys have an RFID microchip inside the key that transmits a unique number to the car every time it is inserted into the ignition. It is designed to ensure that only the correct key is able to start the engine and also prevent theft. If you'd like to learn more about the technology's working get in touch with your local locksmith or dealer for a demonstration.

When the transponder key is inserted into the ignition, it transmits a signal to the chip inside the engine control unit (ECU). The ECU checks if the code on the key corresponds to the digital serial number of the ECU. If it does, then the ECU disables the immobilizer in order to allow the engine start. If the code doesn't match, the ECU will reject it and prevent the engine from starting.

These keys are more expensive than traditional keys but provide additional security. However, car thieves have adapted over time and have found ways to get around this anti-theft system and so the additional 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 professionals who can help you. Besides, the process can differ based on your vehicle's make and model.

Mechanical Keys

Many older Nissan cars came with mechanical keys. These traditional keys made of steel did not feature remote functions, and were only able to unlock the doors and ignition cylinders on the car. Locksmiths can repair the internal parts of a damaged key or a damaged case to create a new key that functions as good as new. A reputable and certified auto locksmith can also cut you a key for a lower cost than a dealership.

There are various kinds of mechanical keys, and each has its unique method of replacement. Linear switches, for instance have a linear actuation graph. This means that as you push the switch down it will move a certain distance until it hits the stopper or triggers an internal spring. The switch will send a signal to start the car once the key is placed in the ignition.

Intelligent keys are equipped with the chip that connects to the computer system of the vehicle. If you lose your key, it will have to be replaced with a new one that is programmed to work with the vehicle. This requires a more advanced key technology, which is only accessible through a specialized locksmith for automobiles. It is more expensive than a regular key replacement at the dealership.

Key Fobs

Key fobs have been a standard feature in most cars since the late 1990s. You can unlock, lock or arm your car's alarm at the click of a switch. Many people believe that these systems are so secure that only a person with your key code could drive away with your car. But that's not always the situation. It's possible for less scrupulous individuals to make use of these systems with the simplest of steps.

If your Nissan's key fob isn't working as it should, you may require replacing the battery. The rechargeable CR2025 or CR2032 batteries that are found in all key fobs can last for around two years. If you're not certain how to change the battery, refer to the owner's manual to get advice.

If your key fob does not work because of a serious issue, you may have to replace or program it. These problems can be more difficult to resolve than an easy battery replacement and may require the help of an expert auto locksmith. Some locksmiths specialize in the repair and replacement of smart keys, and they are able to offer you an OEM smart key at less than the dealership. They can also come to your house, preventing you from having to leave your vehicle at a service centre. They are available all hours of the day seven days a week.

Remotes

There are some Nissan models that feature a remote keyless entry system which utilizes a key fob to unlock your door and/or to start the engine. It is recommended to have a spare for the event that yours gets lost.
