Car Key Repair - How to Fix a Dead Remote Car remotes offer excellent convenience for drivers. They can unlock doors, open trunks and even start the car. However, they can stop working at odd times. If you discover that your key fob is no longer working, try a few fixes before going to the dealership. These steps could save you money. Keyless Entry System You don't need to search for keys in your pockets or purse. Just walk up to your vehicle, press the button on the keyfob and the doors will unlock and the engine will get started. It's a useful feature that has made the experience of car driving more enjoyable and more secure. But, like all devices it's possible that the keyless entry system could be damaged by repeated use or because of other factors. If you are having issues with yours, you may either visit the dealer or phone an locksmith. The way that a keyless entry system operates is by sending radio signals, and then searching for a response signal from the key fob. If the system detects the signal, the car's doors are not locked and the onboard computer is activated. Certain systems include a second transmitter on the trunk of the car that can be opened when you put one foot underneath it. Each key fob is assigned an unique identification code by the manufacturer. A unique process of technology known as "programming" is used to make sure that the fob is set up to work with the specific car's system. This involves turning on the ignition of the car repeatedly in a predetermined sequence, and may also require pulling buttons or levers or levers or even removing the fuse. Once a key fob is programmed to your specific vehicle's keyless entry system it transmits its digital identification code along with a function code that tells the car what to do (lock, unlock or open the trunk). The receiver in the car confirms that the transmitter is the person it claims to be by using an authentication and encryption procedure. If it is authorized, the onboard computer unlocks vehicle and begins the engine. There are concerns that a clever criminal could intercept the code transmitted between the key fob and the car. This would require the use of a device that records the transmission and then transmits it again when the system doesn't expect it. Most keyless entry systems use rolling codes to stop this. This ensures that every new signal from a transmitter received by a car has a counter that differs from the previous one. Batteries A dead battery is the most common reason for the car remote to not function. If you have an extra key fob it's a simple and inexpensive fix. The majority of fobs are powered by watch-style batteries that can be purchased at hardware stores or big-box stores for less than $10.

If you have to move them, do it very gently, as some key fobs have fasteners that easily open and scatter key fob parts across your living room. The case of most key fobs is equipped with a single screwdriver hole. To open it, you can use a tool to pry it open. But, to start, wedge the pry tool along the outside edge of the case as you would do when peeling an orange or apple. Be careful not to apply too much pressure, as the case of the fob is usually made of plastic and may break or crack if apply too much force to it. When you're ready for replacing the battery, be sure to match the size and type to your key fob. Some key fobs have two batteries while others only need one. The wrong battery can cause your remote to become useless. If the issue continues then you can try it again with your fob's key after installing the new battery. If it doesn't work you'll need to determine whether your fob is suffering from something more complicated that requires a professional diagnosis.
