Nissan Car Key Replacement
Replacing the Nissan key fob battery is generally an easy and straightforward 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 need your key code, which should be kept in a secure place and should match the one that came with your vehicle.
Transponder Keys
A lot of the time, in newer automobiles transponder keys usually contain an RFID microchip in the key that transmits a unique number to the car when it is inserted into the ignition. It is designed to prevent theft by making sure that only the right key is able to start the vehicle. If you'd like to learn more about the technology's working call your local locksmith or dealership for a demonstration.
When the transponder key is inserted into the ignition, it transmits a signal to the chip within the vehicle's engine control unit (ECU). The ECU then checks to see 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 allows the engine to begin. If the code doesn't in line, then the ECU will refuse to accept the signal and stop the engine from beginning.
These keys are more expensive than traditional keys but provide added security. The cost of these keys is higher than traditional keys made of metal but they offer greater security.
Many people wonder if you can copy transponder keys by themselves. The answer is yes, but it's best to leave it to a professional auto locksmith. The process can also vary dependent on the make and model of your vehicle.
Mechanical Keys
Many older Nissan automobiles came with mechanical keys. The traditional keys made of metal did not have remote functions, and were capable of unlocking the doors and ignition cylinders of the car. If your key is damaged or breaks, the case is damaged, a locksmith can usually repair the internal components and make a replacement that works like new. A reputable and qualified auto locksmith will also be able to make a new key for a much lower cost than what the dealership would charge.
There are a few different kinds of mechanical keys, each of which has their own distinct replacement procedure. Linear switches, for example come with a linear-actuation graph. When you press the key down, it will move until it reaches the stopper. When the key is put into the ignition the switch will send an indication to the car to turn it up.
Intelligent keys contain a chip that communicates with the computer system of the vehicle. If you lose your key, it will have to be replaced with a fresh one programmed to work for the vehicle. This requires a more advanced key technology that is only available through a specialized locksmith for cars . It will cost more than a standard key replacement at the dealership.
Key Fobs
Key fobs have been an everyday feature in the majority of cars since the latter part of the 1990s. They allow you to 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 a person who has access to your key code can drive off with your car. However, this isn't always the situation. It's possible for less scrupulous individuals to profit from these systems in a few easy steps.
If your Nissan's key fob has stopped working as it should, you may need to replace the battery. Most key fobs are powered by rechargeable CR2025 or CR2032 batteries, and they usually last about two years. Consult your owner's guide for directions if you're unsure how to replace the battery.
If your key fob isn't functioning due to a more serious problem, it may need to be replaced or programmed. These issues are more difficult to resolve than an easy battery replacement and they might require the assistance of a professional auto locksmith. Certain locksmiths specialize in replacing and repairing smart keys, and they can offer you an OEM smart key at cheaper than the dealership. They are also able to be at your location, avoiding you the headache of leaving your vehicle at an establishment for service. They are open 24 hours a day seven days a week.
Remotes
There are Nissan models that come with a remote keyless entry system, which uses a key fob to unlock your door and/or turn on the engine. It is recommended that you have a spare for the event that yours gets lost.
A working replacement key fob will save you the cost of a tow to the dealership and the pricey replacement cost for your ignition keys. Fobs emit a sound that communicates with the vehicle's onboard computer to complete a sequence of actions, including locking or unlocking the doors as well as activating the trunk release, or triggering the alarm for panic.
