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 need your key code, which you should keep in a safe place and must match the one of your vehicle.
Transponder Keys
Transponder keys are typically found in newer vehicles. They feature an RFID microchip that transmits a unique vehicle code when keys are inserted into the ignition. It is designed to ensure that only the right key can start the engine and also prevent theft. If you'd like to learn more about how this technology works call your local locksmith or dealer to schedule an explanation.
When the transponder keys are inserted into the ignition, it transmits an electronic signal to the chip inside the vehicle's engine control unit (ECU). The ECU is then able to determine whether or not the code in the key is in line with its digital serial number. If it does, the ECU will release the immobilizer to allow the engine start. If the code isn't compatible, the ECU will reject it and prevent the engine from beginning.
They are more expensive than traditional keys, but provide additional security. However, car thieves have adapted to the changing times and have found ways around this anti-theft measure therefore the extra cost isn't enough to stop them completely.
Many people are wondering if they could copy a transponder keys themselves - the answer is yes, but it's best to leave the job to professional auto locksmiths. The process may differ according to the make and model of your car.
Mechanical Keys
Many older Nissan automobiles were equipped with mechanical keys. These keys were made of metal and didn't have remote functions, and were capable of unlocking the doors and ignition cylinders on the car. Locksmiths can replace the inner components of a key that is damaged or a damaged case to create a new key that functions as good as new. A reputable and qualified auto locksmith is also able to make a new key at a less cost than the dealership will charge.
There are a variety of types of mechanical keys, each of which has its own unique replacement method. Linear switches, for example have a linear actuation graph. As you press the key down it will move until it hits a stopper. The switch will send the signal to start the car when the key is placed in the ignition.
Intelligent keys have an internal chip that communicates with the computer system in your vehicle. This means that when you lose your key 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, only available through an automotive locksmith. It is more expensive than a standard replacement key at the dealership.
Key Fobs
Key fobs have been an everyday feature in the majority of cars since the latter part of the 1990s. You can unlock, lock or arm your car's alarm at the push of a button. Many people believe that these systems are safe enough that only those with your keycode can escape with your car. But this isn't always true. With just a few steps, less scrupulous people can exploit these systems.

If your key fob won't turn on due to a more serious problem, it may need to be replaced or programmed. These issues may be more complex than replacing the battery and might require assistance from an auto locksmith. Some locksmiths specialize in replacing and repairing smart keys, and can offer you an OEM intelligent key for less than the dealership.
