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 need your key code, which you must keep in a secure place and should be the same as that of your vehicle.

Transponder Keys

Transponder keys are commonly used in newer cars. They are equipped with an RFID microchip that emits a unique car number when keys are inserted into ignition. It is designed to ensure that only the right key can start the engine and prevent theft. Contact your local dealership or locksmith for a demonstration of this technology.

When the transponder is placed into the ignition, it sends an information to the chip that is inside the engine control unit (ECU) of the vehicle. The ECU checks to see if the key's code on the key corresponds to the digital serial number of the ECU. If it does, the ECU then disengages the immobilizer and permits the engine to begin. If the code does not match with the ECU will deny the signal and prevent the engine from starting.

These keys are more expensive than traditional keys, however they provide added security. However car thieves have changed over time and found ways to get around this anti-theft system therefore the extra cost is not enough to keep them from doing anything.

Many people wonder if it is possible to copy a transponder-key yourself. The answer is yes. However, it's best to leave it to auto locksmiths. The procedure can vary according to the make and model of your car.

Mechanical Keys

Many older Nissans came with mechanical keys. These keys, which were made of metal, were not equipped with remote functions and were used to open the doors of the vehicle and the ignition cylinders.

There are various kinds of mechanical keys and each one has its distinct method of replacement. Linear switches, for example are equipped with a linear actuation graph. This means that as you press the key down it will move down a certain distance until it hits an obstruction or triggers an internal spring. When the key is put into the ignition, the switch will send a signal to the car to start it up.

Intelligent keys are equipped with a chip inside them that communicates with the vehicle's computer system. If you lose your key, it will have to be replaced by a new key that is programmed for the vehicle. This requires a more sophisticated key technology, only accessible through a specialized locksmith for automotive. It is more expensive than a typical key replacement at the dealership.
