Learn button colours explained
The square Learn button on LiftMaster, Chamberlain and Craftsman openers is colour-coded. The colour tells you the radio technology inside, so it decides which remotes, keypads and cars will pair with it.

No coloured button?
Older openers (before about 1993) and some other brands use small DIP switches instead. You'll find them inside the remote's battery cover and on the motor unit. Set the switches in the new remote to match the opener.
