This battery is what you need for almost all of the liftmaster series hand held remotes. they will also work on the Craftsman, Sears, and Chamberlain hand held remotes. They are easy to change and easy to re program. Just pop off the visor clip and pry open the remote casing to access the battery's, most of the online stores sell them and there reasonably priced if you shop around. Most of the hand held remotes need two battery's. Another point to remember is make sure you place them back in the right direction when replacing them. the + is usually marked on the remote.
