Copies
A key fob is a small device that provides access to and control over the functions of a vehicle without the physical key. These devices are subjected to lots of abuse and are not indestructible. They also contain a myriad of components that could break or malfunction. Fortunately, most of these parts are repairable. The battery terminal contacts and buttons are the most common failure point, but there are other issues that could happen.
The car key fobs communicate with the vehicle by radio frequency. They have specific tags that are unique to the car. When they are pressed, they transmit the information from the tag to the vehicle, so they can open or unlock the door, or even start the motor. A car key fob is more practical than conventional keys that must be in the ignition to activate the features.
