Nissan Car Key Replacement

Replacing a Nissan key fob battery is typically 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 also need the key code that should be kept in a secure location and should match with the one that came with your car.

Transponder Keys

Transponder keys can be found in modern vehicles. They come with an RFID microchip that sends a unique code for the car when keys are inserted into the ignition. It is designed to ensure that only the correct key can be used to start the engine and stop theft. If you'd like to learn more about the technology's working get in touch with your local locksmith or dealer to schedule an explanation.

When the transponder keys are inserted into the ignition, it transmits a signal to the chip in the engine control unit (ECU). The ECU then examines whether or not the number in the key is in line with its digital serial number. If it does, then the ECU will release the immobilizer to allow the engine start. If the code does not match it, the ECU will refuse to accept it and stop the engine from starting.

These keys are more expensive than traditional keys, however they offer additional security. The cost of these keys is higher than traditional metal keys but they offer greater security.

Many people ask if it is possible to duplicate the transponder key yourself. The answer is yes. But, it's better to leave it up to auto locksmiths. The process may differ depending on the make and model of your vehicle.

Intelligent keys are equipped with an embedded chip that communicates with the vehicle's computer system. If you lose your keys, it will have to be replaced by a new one programmed to work for the vehicle.
