Nissan Car Key Replacement
Nissan key fob batteries are easy 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 require your key code, which you must keep in a safe location and should be the same as that of your car.
Transponder Keys
Transponder keys are typically found in modern vehicles. They have an RFID microchip that sends a unique code for the car when the key is placed in ignition. The idea behind this technology is to prevent theft by ensuring that only the right key can be used to start the vehicle. If you'd like to find out more about the technology's working, contact your local locksmith or dealer to schedule an explanation.
When the transponder key is inserted in the ignition, it transmits a signal to the chip in the engine control unit (ECU). The ECU determines if the code on the key corresponds to the digital serial number of the ECU. If it does, the ECU is then able to disengage the immobilizer, allowing the engine to start. If the code is not compatible then the ECU will refuse to accept it and stop the engine from beginning.
These keys are more costly than traditional keys made of metal, but they are safer. However car thieves have evolved over time and found ways around this security measure and the additional cost won't stop them completely.
Many people wonder if you can copy transponder keys by themselves. The answer is yes but it's better to leave the job to professional auto locksmiths. Additionally, the process could differ based on your vehicle's model and make.
Mechanical Keys
Many older Nissans had mechanical keys. These keys, which were made of metal, did not have remote functions and could only be used to open the doors of the car and the ignition cylinders. A locksmith can replace the inner components of a broken key or a damaged case and create a replacement key that functions like new. A reputable and experienced auto locksmith is also able to cut a new key for a much lower cost than the dealership charge.
There are a variety of mechanical key, and each has its particular method for replacement. Linear switches have a linear actuation chart for example. As you press the key down it will move until it comes to an obstruction. The switch will send a signal to start the car once the key is inserted into the ignition.
Intelligent keys are equipped with a chip inside them that communicates with the vehicle's computer system. If you lose your keys, it will have to be replaced by a new one that is programmed to work with the vehicle. This requires more advanced key technology that is only accessible through a specialized locksmith for automobiles. It will cost more than a typical key replacement at the dealership.
