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 also require your key code, which must be stored in a secure location and should match the one that came with your car.

Transponder Keys

Transponder keys are commonly found in newer vehicles. They are equipped with an RFID microchip that transmits a unique vehicle code when the key is inserted into ignition. The idea behind this technology is to prevent theft by ensuring that only the proper key is able to start the car. Contact your local dealership or locksmith to view an example of this technology.

When the transponder gets inserted into the ignition, the key transmits an electronic message to the chip inside the engine control unit (ECU) of the vehicle. The ECU checks if the code on the key is compatible with the serial number of the ECU. If it does, then the ECU will release the immobilizer to allow the engine to start. If the code isn't compatible then the ECU will reject it and prevent the engine from starting.

They are more expensive than traditional metal keys but offer additional security. The cost of these keys is higher than traditional keys made of metal but they offer greater security.

Many people wonder if it is possible to duplicate the transponder-key by yourself. The answer is yes. However, it's best to leave it up to auto locksmiths. Besides, the process can vary based on the vehicle's make and model.

Mechanical Keys

Many older Nissan automobiles came with mechanical keys. These traditional metal keys were not equipped with remote functions and could only be used to open the doors of the car and the ignition cylinders. If your key breaks or the case is damaged, a locksmith can typically replace the internal parts and make a replacement that works as good as new. A reputable and experienced auto locksmith can also cut a key for a lower cost than a dealership.

There are several kinds of mechanical keys each with its own unique replacement method. Linear switches for instance have a linear actuation graph. As you press the key down, it will move until it comes to an obstruction. When the key is put into the ignition, the switch will send an electronic signal to the car to start it up.

Intelligent keys have an electronic chip that communicates with the computer system of the vehicle. If you lose your key it will need to be replaced with a brand new one that has been programmed to work with the vehicle. This requires a more sophisticated key technology, only accessible through a specialized locksmith for cars. It is more expensive than a standard key replacement at the dealership.

Key Fobs

Key fobs have been a standard feature in most cars since the latter part of the 1990s. You can lock, unlock and arm your car's alarm with the push of a button. Many people believe that the systems are secure enough that only someone who knows your key code can drive off with your vehicle. However, this isn't always the case. In a few simple steps, even the most sloppy of people could take advantage of these systems.

If your Nissan's key fob doesn't function as it should, you may need to replace the battery. The rechargeable CR2025 and the CR2032 batteries used in most key fobs last about two years. Refer to the owner's guide for instructions if you are uncertain about how to replace the battery.

If your key fob does not function because of a serious problem, you may need to replace or program it. These issues can be more complex than an easy replacement of the battery and might require the assistance of an auto locksmith. Certain companies specialize in replacing and repairing smart keys and will provide you with an OEM intelligent key at a cheaper cost than the dealer. They are also able to come to your home, saving you from having to leave the vehicle at a service centre. They are available all hours of the day seven days a week.

Remotes

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

A replacement key fob that works can help you avoid having to pay for a tow or the cost of replacing your lost ignition keys. Fobs emit frequencies that communicate with the car's computer to perform a variety of tasks like locking and unlocking doors or trunk release, and sounding a panic alarm.

Just be sure to select the right style, as some look similar and can cause headaches if not compatible. Also, online sellers offering a pre-programmed fob typically require evidence of ownership or registration in order to verify the legitimacy of the product. Sites that do not require this information might be a scam.
