Some garage door systems have a keypad. These keypads are usually installed outside your garage door. These keypads characteristically use a 9V battery or a couple of AA batteries. The main advantage of these keypads is that users don’t need a key to enter their garage, they just need to type a code. If the keypad doesn’t light or respond when you enter your code, the keypad battery is most likely the reason why.
