One wireless keypad listing names 377LM. That listing describes itself as covering openers manufactured since 1993, which is the broadest claim made by anything in this index and correspondingly the least specific. A date range is not a model list, and a seller asserting one has not told you that your opener is inside it.
Generation
Not established here. No listing collected for this site ties this model number to a Learn button color, a frequency or a date range. What the button colors do say.

Read the listing
How to check this yourself
- Check that your existing unit is a wall-mounted keypad. The listing that names 377LM here is a keypad, and a remote is a different replacement job.
- Read the opener model number and the manufacture date from the motor unit label, since the listing frames its claim in terms of when the opener was made.
- Check the Learn button color against the manufacturer chart, and note where your unit sits relative to the year ranges that chart gives.
- Confirm 377LM is printed in the listing body text before buying, not merely in the search title.
- If your opener predates the range the listing claims, treat the question as unanswered rather than assuming the claim stretches.
Two different numbers
- The number on your remote and the number on your opener motor unit are different things. This page is about the model number as the listings print it, not about your opener generation.
- Nothing on this page infers compatibility. If a listing does not name your model, this site will not name it either.
