How to Change the Liftmaster Garage Door Battery
In this video Precision Garage Door of New Jersey provides instructions on changing your garage door remote battery.
Be sure you know what type of battery your remote uses. In this video, you'll notice we're working with a nickle sized wafer battery, which normally has a lifespan of 2 years. Also, make sure you have a flat head screwdriver or small knife to pop open the remote casing and access your battery.
Before you raid your tool box for batteries and screwdrivers, you might want to check your wall control unit first, as the lock/vacation button may have accidentally been pressed.
