Nissan Car Key Replacement
Replacing the Nissan key fob battery is generally 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 must be stored in a secure place and should match the one that came with your car.
Transponder Keys
Commonly found in newer vehicles transponder keys usually include an RFID microchip inside the key which transmits a unique code to the car whenever it is put into the ignition. It is designed to stop theft by ensuring that only the proper key can be used to start the vehicle. If you'd like to learn more about the technology's working, contact your local locksmith or dealer to schedule a demonstration.
When the transponder key is inserted into the ignition, it sends an indication to the chip in the engine control unit (ECU). The ECU then checks to see whether the code on the key is in line with its digital serial number. If it does then the ECU then disengages the immobilizer, allowing the engine to begin. If the code does not match, the ECU will reject it and stop the engine from beginning.
They cost more than traditional keys, but provide added security. The cost of these keys is higher than traditional keys made of metal however they offer more security.
Many people wonder if is possible to duplicate the transponder-key by themselves. The answer is yes. However, it's preferential to leave it to auto locksmiths. The process can also vary depending on the make and model of your vehicle.
Mechanical Keys
Many older Nissans had mechanical keys. These keys, which were made of metal, were not equipped with remote functions and were used to open the doors of the car and the ignition cylinders. Locksmiths can repair the internal components of a damaged key or damaged case to create a new key that functions just like the original. A licensed and reputable auto locksmith can also cut you keys at a lower cost than a dealership.
There are various kinds of mechanical keys, and each has its distinct method of replacement. Linear switches for instance have a linear actuation graph. This means that as you push the switch down it will move certain distance until it hits a stopper or actuates an internal spring. The switch will send a signal to start the car once the key is put into the ignition.
Intelligent keys contain a chip inside them that communicates with the vehicle's computer system. This means that when you lose your keys, it will have to be replaced with a new one that is programmed to work with your particular vehicle. This requires a higher level of key technology that can only be obtained from a specialized automotive locksmith, and will cost you more than a regular replacement key at the dealership.
Key Fobs
Since the end of the 1990s, key fobs have been a common feature in all cars. You can lock, unlock and arm your car's alarm at the press of a button. Many people believe that these systems are safe enough that only those with your keycode can leave your car. However, that's rarely the case. With just a few steps, even the most sloppy of people could take advantage of these systems.
If your Nissan's key fob has stopped working as it should, you may need to replace the battery. The rechargeable CR2025 as well as CR2032 batteries found in most key fobs last about two years. If you're not sure of how to replace the battery, check the owner's manual to get advice.
If your key fob doesn't work due to a more significant problem, it may need to be replaced or programmed. These problems can be more difficult to fix than the simple replacement of batteries, and might require the assistance of a professional auto locksmith. Some locksmiths specialize in repair and replacement of intelligent keys and will provide you with an OEM intelligent key at a cheaper cost than the dealer. They are also able to deliver to you, thereby saving you the inconvenience of having to drop off your vehicle at the service center. They are also on-call all day, all week.
Remotes
Certain Nissan models have a remote keyless system that utilizes an electronic key fob to unlock the door and/or start your engine. A spare key in case you lose yours is highly recommended.
A key fob replacement that works can save you from having to pay for a tow and the expense of replacing your lost ignition keys. Fobs emit a frequency that communicates with the car's computer to complete a sequence of tasks, such as locking or unlocking the doors and activating the trunk release, or sounding the alarm to alert you to a panic.
