Nissan Car Key Replacement
Replacing the Nissan key fob battery is typically 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 kept in a safe location and must match the one that came with your car.
Transponder Keys
Transponder keys are typically found in newer vehicles. They are equipped with an RFID microchip that transmits a unique vehicle code when keys are inserted into ignition. It is designed to guard against theft by making sure that only the correct key can start the vehicle. Contact your local dealer or locksmith to view a demonstration of this technology.
When the transponder key is inserted in the ignition, it transmits an electronic signal to the chip inside the engine control unit (ECU). The ECU then examines whether the code contained in the key matches with its own digital serial number. If it does, the ECU will then release the immobilizer and permits the engine to start. If the code is not compatible with the code, the ECU will refuse to accept it and stop the engine from starting.
They are more expensive than traditional keys, however they give you extra security. However car thieves have changed over time and have found ways to circumvent this anti-theft device therefore the extra cost is not enough to deter them entirely.
Many people wonder if you can copy transponder keys at home - 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
Many older Nissans had mechanical keys. These traditional metal keys did not come with remote functions and were used to unlock the doors of the car and the ignition cylinders. If your key breaks or the case is damaged, a locksmith can usually repair the internal parts and make a replacement that operates like new again. A reputable and experienced auto locksmith should also be able to cut you a brand new key at a much lower price than the dealership will charge.
There are several kinds of mechanical keys that each have their own distinct replacement procedure. Linear switches are equipped with the ability to operate in a linear manner, for instance. This means that as you press the key down it will move a certain distance until it reaches the stopper or triggers an internal spring. The switch will send a signal to start the car when the key is placed in the ignition.
The KeyLab have an electronic chip that communicates with the computer system of the vehicle. This means that when you lose your key, it will need to be replaced with a brand new one that is programmed to work with the specific vehicle. This requires more advanced key technology, only available through a specialized locksmith for cars. It will cost more than a standard key replacement at the dealership.
Key Fobs
Since the late 1990s key fobs are a standard in all automobiles. They let you unlock, lock and arm the car's alarm with a push of a button. Many people assume that the systems are secure enough that only someone who knows your key code can drive off with your vehicle. Unfortunately, this is not always the case. It is possible for less cautious people to take advantage of these systems in only a few simple steps.
If your Nissan's key fob isn't working as it should, you might need to replace the battery. The rechargeable CR2025 and CR2032 batteries found in most key fobs can last for around two years. Look up the owner's manual for directions if you're not sure how to change the battery.
If your key fob isn't functioning because of a more serious issue, it might have to be replaced or programmed. These issues may be more complicated than simply replacing the battery and could require the assistance of an auto locksmith. Some locksmiths specialize in repairing and replacing smart keys, and can provide you with an OEM smart key at a much lower price than the dealership. They can also be at your location, avoiding you the hassle of having to leave your vehicle in an auto repair shop. They are also on-call all hours of the day, seven days a week.
Remotes
There are some Nissan models that feature a remote keyless entry system, that uses the key fob to open your door and/or start the engine. It is recommended that you have a spare in the event that yours gets lost.
A functional replacement key fob will help you avoid the cost of an expensive tow to the dealer and the pricey replacement cost for your ignition keys. Fobs emit a sound that communicates with the car's onboard computer to complete a series of actions, including locking or unlocking the doors, activating the trunk release, or triggering the panic alarm.

Sites that do not request this information could be scams.
