Nissan Car Key Replacement

Replacing a nissan micra replacement key key fob battery is generally a quick and simple 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 require your key code, which must be kept in a secure place and should match the one that came with your vehicle.

Transponder Keys

Commonly found in newer vehicles, transponder keys contain an RFID microchip inside the key that transmits a unique code to the car every time it is installed in the ignition. It is designed to ensure that only the right key can start the engine and also prevent theft. Contact your local dealership or locksmith to view an example of this technology.

When the transponder is put into the ignition, the key transmits a message to the chip inside the engine control unit (ECU) of the vehicle. The ECU then checks to see whether or not the code in the key matches its own digital serial number. If it does, the ECU disengages the immobilizer so that the engine can start. If the code is not matched, then the ECU will deny the signal and prevent the engine from getting started.

These keys are more expensive than traditional metal keys but give you extra security. However car thieves have developed over time and found ways to get around this anti-theft system therefore the extra cost won't stop them completely.

This means that as you press the key down it will move a certain distance until it hits the stopper or triggers an internal spring. When the key is pushed into the ignition, the switch will send an electronic signal to the car to turn it up.

Intelligent keys have an electronic chip that communicates with the computer system of the vehicle. If you lose your keys, it must be replaced with a fresh key that is programmed for the vehicle.
