Liftmaster
390 MHz Billion Code three-channel visor transmitter for older Liftmaster, Chamberlain, and Sears Craftsman openers with 9-position DIP switch coding. The 63LM is the standard "no-rolling-code" three-button replacement for openers made between 1984 and 1993.
Confirmed-compatible openers, receivers, and the older remotes this part replaces. If your model isn't listed, send us a photo and we'll verify before you buy.

The 63LM is for older openers with 9 small DIP switches inside. If your opener has a colored "learn" button instead, you need the 373LM (purple) or 973LM (green/orange/red).
Each button has its own independent 9-switch DIP block. Match each button to a different receiver to control three doors.
Pick a unique pattern for each opener. Avoid all-up or all-down patterns to reduce conflict risk with neighbors.

Works as expected. Wish the buttons had more tactile feedback but the range is excellent.
