Car remotes provide a great convenience to drivers. They can unlock doors, open trunks and even start the engine. However, they can cease to function at uninviable times.

If the system recognizes the signal, the vehicle's doors are opened and the onboard computer activated. Some systems have a second receiver on the car's trunk that will open automatically when you move your foot under it.

Each key fob comes with an individual digital identity code that's given by the manufacturer. A proprietary technical process called "programming" is used to configure the fob to work with the specific car's system.
