Nissan Car Key Replacement

Replacing a Nissan key fob battery is usually 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 need your key code which you must keep safe and should be the same as that of your car.

Transponder Keys

Transponder keys are often used in newer cars. They have an RFID microchip that transmits a unique car code when the key is inserted into ignition. It is designed to ensure that only the correct key is able to start the engine and stop theft. Contact your local dealership or locksmith for the demonstration of this technology.

When the transponder is put into the ignition, the key transmits an electronic message to the chip that is inside the engine control unit (ECU) of the vehicle. The ECU is then able to determine whether or not the number in the key matches its own digital serial number. If it does it, the ECU then disengages the immobilizer and permits the engine to begin. If the code does not match it, the ECU will reject it and prevent the engine from starting.

The keys are more expensive than traditional metal keys but give you extra security. The cost of these keys is higher than traditional metal keys however they offer more security.

Many people ask if they can duplicate a transponder key at home - the answer is yes but it's best to leave it to a professional auto locksmith. The process can also vary depending on the brand and model of your car.

Mechanical Keys

Many older Nissan cars came with mechanical keys. These keys were made of metal and did not have remote functions, and were only able to unlock the doors and the ignition cylinders of the vehicle. If your key breaks or the case is damaged, a locksmith will usually replace the inner components and make a replacement that operates like new again. A reputable and certified auto locksmith can also cut a key for a lower cost than the dealership.

There are many different kinds of mechanical key and each one has its distinct method of replacement. Linear switches come with an actuation chart that is linear, for example. As you press the key down, it will move until it reaches an obstruction. When the key is put into the ignition, the switch will send an alert to the car to start it up.

Intelligent keys are equipped with an electronic chip that communicates with the computer system of the vehicle. This means that if you lose your keys, it must be replaced with a new one that is programmed to work with your particular vehicle. This requires a more advanced key technology, only available through a specialist automotive locksmith. It will cost more than a typical key replacement at the dealership.

Key Fobs

Key fobs have become an integral part of many cars since the latter part of the 1990s. You can lock, unlock and arm your car's alarm system with the push of a button. Many people assume that these systems are secure enough that only a person who knows your code can drive off with your car. Unfortunately, that's not always the case. In a few simple steps, people who aren't as meticulous can take advantage of these systems.

If your key fob isn't function due to a significant issue, you may have to replace it or program it. These issues can be more complicated than replacing the battery and may require the assistance of an auto locksmith.

A working replacement key fob can save you the expense of a tow to the dealership and the high cost of replacing the ignition keys that you lost.
