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 also require your key code, which must be kept in a safe location and should match with the one that came with your vehicle.
Transponder Keys
Transponder keys are typically found in modern vehicles. They have an RFID microchip that transmits a unique car code when keys are inserted into the ignition. It is designed to prevent theft by ensuring that only the right key can be used to start the car. Contact your local dealer or locksmith to view an example of this technology.
When the transponder key is inserted in the ignition, it sends a signal to the chip within the engine control unit (ECU). The ECU checks to see if the key's code on the key matches the serial number digital of the ECU. If it does it, the ECU then disengages the immobilizer and allows the engine to begin. If the code is not in line, then the ECU will refuse to accept the signal and stop the engine from beginning.
They are more expensive than traditional keys made of metal however they offer greater security. However car thieves have evolved to the changing times and have found ways around this anti-theft measure and so the additional cost won't keep them from doing anything.
G28CarKeys wonder if you can copy a transponder key themselves - the answer is yes however, it is best to leave it to professional auto locksmiths. The procedure can vary depending on the make and model of your vehicle.
Mechanical Keys
A lot of older Nissans had mechanical keys. These traditional keys made of steel did not come with remote functions, and were only able to unlock the doors and ignition cylinders on the car. If the key you have is damaged or broken, the case is damaged, a locksmith will generally replace the inside parts and make a replacement that operates like new again. A reputable and qualified auto locksmith should also be able to cut you a brand new key at a much lower cost than the dealership will charge.
There are several different types of mechanical keys each with its own unique process for replacement. Linear switches come with a linear actuation chart for example. This means that as you push the button down it will move certain distance until it hits the stopper or triggers an internal spring. When the key is pushed into the ignition the switch will send an electronic signal to the car to turn it up.
Intelligent keys have an internal chip 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 has been programmed to work with the particular vehicle. This requires more advanced key technology, which is only available through a specialized locksmith for cars. It is more expensive than a standard replacement key at the dealership.
Key Fobs
Since the mid 1990s, key fobs have become a standard in the majority of automobiles. They let you unlock, lock and arm the car's alarm at the push of a button. Many people believe that these systems are secure enough that only someone with your key code can escape with your car. However, that's rarely the situation. It is possible for less cautious individuals to profit from these systems in a few easy steps.
It's possible to replace your Nissan key fob's battery if it's not working properly. The rechargeable CR2025 and CR2032 batteries found in most key fobs will last around two years. Consult your owner's guide for the correct procedure if not sure how to replace the battery.
If your key fob does not function due to a major issue, you may need to replace it or program it. These issues may be more complex than a simple replacement of the battery and could require assistance from an auto locksmith. Some companies specialize on replacing and repairing intelligent keys and will provide you with an OEM intelligent key at a cheaper cost than the dealer. They can also deliver the key to your home, saving you from having to leave your vehicle at a service center. They are available 24 hours a day all week long.
Remotes
There are some Nissan models that have a remote keyless entry system which makes use of a key fob to unlock your door and/or start the engine. It is recommended to have a spare in the event that yours is lost.
A functional replacement key fob can save you the expense of an expensive tow to the dealer, as well as the hefty fee to replace the ignition keys that you lost. Fobs emit a frequency that communicates with the car's computer to complete a series of actions, including locking or unlocking the doors as well as activating the trunk release, or sounding the panic alarm.

Just be sure to select the right style, as they all look alike and could cause problems if they are not compatible.
