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 also need the key code that should be kept in a secure place and should match the one that came with your vehicle. Transponder Keys Transponder keys are often found in newer vehicles. They come with an RFID microchip that transmits a unique vehicle code when keys are inserted into the ignition. It is designed to guard against theft by making sure that only the correct key can start the vehicle. If you'd like to find out more about how this technology works, contact your local locksmith or dealer for demonstrations. When the transponder is placed in the ignition, it sends a message to the chip within the engine control unit (ECU) of the vehicle. The ECU examines if the number on the key matches the digital serial number of the ECU. If it does, then the ECU disengages the immobilizer to allow the engine to start. If the code is not compatible with the ECU will reject the signal and keep the engine from starting. They're more expensive than traditional keys made of metal but they are safer. The cost of these keys is higher than traditional keys made of metal but they offer greater security. Many people ask if it is possible to duplicate the transponder keys themselves. The KeyLab is yes. However, it's preferential to leave it to auto locksmiths. The process may differ depending on the brand and model of your vehicle. Mechanical Keys Many older Nissan automobiles came with mechanical keys. The traditional keys made of metal were not equipped with remote functions and could only be used to unlock the doors of the vehicle and the ignition cylinders. If your key is damaged or breaks, the case is damaged, a locksmith will usually replace the inner parts and create a replacement that operates like new again. A reputable and experienced auto locksmith will also be able to cut you a brand new key for a much lower price than the dealership will charge. There are several kinds of mechanical keys that each have its own unique replacement method. Linear switches, for instance, have a linear actuation graph. This means that when you push the key down, it will move a certain distance until it reaches the stopper or activates an internal spring. When the key is put into the ignition, the switch will send an indication to the car to start it up. Intelligent keys contain a chip inside them that communicates with the computer system in your vehicle. If you lose your keys, it will need to be replaced by a new one programmed to work for the vehicle. This requires a higher degree of technology for keys that can only be obtained from a specialized automotive locksmith, and will cost you more than a regular replacement key at the dealership. Key Fobs Key fobs have been a standard feature in most cars since the latter part of the 1990s. You can lock, unlock and arm your car's alarm with the touch of a button. Many people assume that these systems are safe enough that only those who has access to your key code is able to drive away with your vehicle. Unfortunately, this isn't always true. In a few simple steps, people who aren't terribly careful could take advantage of these systems. If your Nissan's key fob has stopped working as it should, you may need to replace the battery. The majority of key fobs utilize rechargeable CR2025 or CR2032 batteries, and they generally last around two years. Consult your owner's guide for the correct procedure if unsure how to replace the battery. If your key fob won't work because of a serious issue, you may need to replace it or program it. These issues can be more complicated than an easy replacement of the battery and could require an auto locksmith's help. Some locksmiths specialize in replacing and repairing smart keys, and can provide you with a OEM intelligent key for a lower cost than the dealer. They are also able to be at your location, avoiding you the headache of leaving your vehicle at the service center. They are open 24 hours a day and 7 days a week. Remotes Certain Nissan models come with a remote keyless system that makes use of an electronic key fob to unlock the door and/or start the engine. A spare key in case you misplace yours is highly recommended. A replacement key fob that works could help you avoid having to pay for towing and the expense of replacing your lost ignition keys. Fobs emit frequencies that communicate with the car's computer to perform a variety of tasks like locking and unlocking doors, activating trunk release or sounding a panic alarm.
