A key fob is a small handheld remote used to control vehicle functions such as lock, unlock, trunk release, and panic alarm. In many cases, the term “key fob” refers to a remote that works separately from the metal key, but it can also describe smart keys and other remote entry devices.
A key fob makes everyday vehicle access more convenient by letting you control certain features without inserting a key into the door. Depending on the vehicle, a replacement key fob may need to be programmed to the car before it will work correctly.
When replacing a key fob, it is important to verify the vehicle year, make, model, FCC ID, frequency, and button configuration. Some key fobs are remote-only, while others also include a transponder or proximity function.
