What Is a GMC Key Fob and Why Is Battery Replacement Necessary?
A GMC key fob is a remote control device that allows drivers to unlock and start their vehicles from a distance. It uses radio frequency technology to communicate with the car’s central locking system.
According to GM’s official website, key fobs provide convenience and security by enabling keyless entry and ignition features. They may also include additional functionalities such as remote start and panic alarms.
GMC key fobs typically contain a small battery that powers their electronic components. When the battery weakens or dies, the key fob may fail to operate, leaving the driver unable to access their vehicle or start the engine.
