They allow you to unlock doors, gain access to trunks and even start the engine. However, they can cease to function at uninviable times. If you notice that your key fob is not working, try a few simple fixes before heading to the dealership. These tips could save you money. Keyless Entry System You don't have to look for keys in your pockets or purse. Just walk to your car, press the button on the keyfob and the doors will unlock and the engine will get started. It's a convenient feature that has made the experience of car driving more enjoyable and safer. The keyless entry system, just like any other device, could be damaged through repeated use or other elements. If you've had issues with yours, you have two options: Visit the dealer or contact an emergency locksmith in your area. A keyless entry system operates by sending radio signals, and then looking for a response signal from a key fob. If the system recognizes the signal, the car's doors are opened and the onboard computer is activated. Certain systems have a second transmitter on the trunk of the car which opens when you move a foot under it. Each key fob is assigned a unique digital identification code by the manufacturer. The fob is programmed by a proprietary process called "programming". This requires turning the ignition of the car several times in a specific sequence. It may also require pushing or pulling levers or buttons or even removing the fuse. Once a key fob has been programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car to (lock the trunk, unlock it or open the trunk). The car's receiver confirms that the transmitter is who it claims to be by using an authentication and encryption procedure. If it's authorized, the computer on board unlocks the vehicle and then starts the engine. T
