Opener model

373LM

Three listings name 373LM: two multi-button handheld remotes and one keychain remote. The keychain listing is the only one in this entire index that also prints Learn button colors, and it prints four of them without saying which applies to which number. That is a useful clue about the generation the seller has in mind and it is not a statement about your opener.

How to check this yourself

1. Photograph the opener motor unit label. Everything else on this list depends on having that number in front of you.
2. Note your Learn button color, then read the keychain listing that names 373LM and see whether your color is among the four it prints.
3. Treat a color match as a reason to keep reading rather than as an answer, because the listing does not pair any specific color to any specific model number.
4. Decide between a keychain format and a visor format before you buy. Both are named against 373LM here and they are different objects to live with.
5. Confirm the number appears in the description text of whichever listing you choose, and take a screenshot of it in case you need to return the part.
