One keypad listing names 977LM, grouping it with 377LM, 66LM, 877MAX and 878MAX. That grouping is the seller’s own, and it is the entirety of what this site holds about 977LM. Reading anything into which numbers a seller chose to put in a list, or into the order they appear in, would be inventing information.

Read the listing
How to check this yourself
- Verify the format first: an outside keypad, entered by PIN, rather than a handheld remote.
- Photograph the motor unit label for the opener model number, and note anything printed about frequency while you are there.
- Check the Learn button color and the antenna wire color, and treat disagreement between them as a sign the button has faded.
- Look for 977LM in the description of any keypad you are considering, and read what else that listing claims.
- Where a listing groups 977LM with other numbers, understand that the seller has offered the item against the group and has said nothing about the members individually.
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.
