Nissan Car Key Replacement

Replacing a nissan qashqai key key fob battery is typically an easy and simple task. 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 secure location and should match with the one that came with your vehicle.

Transponder Keys

Transponder keys can be found in more modern vehicles. They have an RFID microchip that transmits a unique car code when keys are inserted into ignition. It is designed to prevent theft by making sure that only the correct key can start the car. Contact your local dealer or locksmith for the demonstration of this new technology.

When the transponder key is inserted into the ignition, it sends an indication to the chip inside the vehicle's engine control unit (ECU). The ECU checks to see if the key's code on the key matches the serial number digital of the ECU. If it does it, the ECU removes the immobilizer and allows the engine to start. If the code does not match it, the ECU will refuse to accept it and stop the engine from beginning.

They are more expensive than traditional metal keys but provide additional security. However car thieves have developed in the past and discovered ways to circumvent this anti-theft device, so the extra cost is not enough to deter them entirely.

Many people are wondering if they can copy transponder keys for themselves. The answer is yes but it's best to leave the job to professional auto locksmiths. The process can also vary depending on the brand and model of your car.

Mechanical Keys

Many older Nissans were equipped with mechanical keys. These traditional keys made of steel 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 parts and make a replacement that works as good as new. A reputable and certified auto locksmith can also cut you a new key at a less cost than what the dealership would charge.

There are various kinds of mechanical keys each with their own distinct replacement procedure. Linear switches, for instance are equipped with a linear actuation graph. As you press the key down, it will move until it comes to a stopper. The switch will send a signal to start the car once the key is inserted into the ignition.

Intelligent keys are equipped with an embedded chip that communicates with the vehicle's computer system. This means that when you lose your key it will need to be replaced with a new one that has been programmed to work with the particular vehicle. This requires a more advanced key technology that is only available through a specialist locksmith for automobiles. It is more expensive than a standard key replacement at the dealership.

Key Fobs
