Source: https://ift.tt/2J3FxFR key fob makes it easier to get into vehicle by unlocking and locking the doors. Some are separate from the key fob and others have the key built right in. The other key fobs are called “smart keys” where you don’t even have to take the key fob out of your pocket to open the trunk, doors, or even start the car. The battery is used by the key fob to control these remote functions. The battery being weak or dead does not prevent you from starting your vehicle, only from using the fob itself. Replacing the battery is easy and they can be found at autospeedz.comMore detailed instructions are found at https://ift.tt/2sjD582 hope this was help to everyone.
