If your door opener is from Stanley, Genie, Linear, or Wayne-Dalton, there is a way to install a “universal” wireless keypad, the 387LM. If you have another brand of door opener, LiftMaster products are not compatible. If you are at all unsure, bring your remote control with a photo of your door opener to us at our store. We will then be able to evaluate whether a wireless exterior keypad can be added to your system.
