A key fob is a small electronic device that allows access to and control over a vehicle's functions without using the physical key. Key fobs are subject to lots of abuse and are not indestructible. They also contain a myriad of parts that may fail or break. Most of these parts are repairable. The most frequent cause of failure is the contacts on the battery terminals or buttons, but there are many other factors that can fail.
The car key fobs communicate with the vehicle using radio frequency. They have unique tags on them that match up with the car, and when pressed they relay the information from the tag to the vehicle, so it can open or lock the door, or start the engine. A car key fob is more convenient than traditional keys that must be in the ignition to activate the features.
Sometimes, it can be a bit confusing when the car key fob starts acting up. Most key fob issues aren't serious and can be easily repaired at home. Cleaning the batteries or replacing them may be all that is needed to solve the problem with your car key fob.
