The AccessMaster 377AC garage door opener wireless keypad entry from Garage Door Supply Company is identical to our LiftMaster 878Max keyless-entry wireless keypad. This keypad is compatible with all LiftMaster, Chamberlain and Sears Craftsman garage door openers with purple learn buttons that were made after 2005.
This 315MHZ AccessMaster garage door opener keypad is equipped with Security+ rolling code technology to prevent thieves from hacking your system. The code changes every time you use the keypad to one of more than 1 billion codes. You can use the keypad's temporary password option to give friends, maintenance workers and others temporary access to your garage. Only two screws are needed to mount it to your garage door jamb.
