LiftMaster, Chamberlain & Craftsman Opener Guides
LiftMaster, Chamberlain, and most Craftsman openers come from the same manufacturer and share the same radio systems, so the steps below work across all three. The one thing that changes the steps is the generation of your opener, and the colour of the learn button tells you which one you have.
Which LiftMaster / Chamberlain opener do I have?
Find the learn button on the motor unit and note its colour and shape. The colour tells you the radio system, and the radio system decides which remotes and keypads will pair. Older buttons fade, so a red one can look orange and a purple one can look brown.
Where to look: On the back or side of the motor unit, near where the antenna wire hangs down. On some models you need to take off the light cover to see it.
