About the 877LM

A keypad means the kids get in after school, the door closes behind you on a run, and there’s no remote to lose. The 877LM mounts outside the garage and opens the door with a personal code, with temporary codes available for guests and service visits on supported models.

We confirm compatibility with your opener before you buy, mount the keypad properly, and program it — done in minutes as part of any visit.

Good to Know

877LM — Common Questions

Does the 877LM fit my opener?

It works with compatible LiftMaster openers — call with your opener’s model number and we’ll confirm before you buy.

Can I give guests a temporary code?

Supported models allow temporary or one-time codes so guests and service people can get in without your main PIN.

What if I forget my code?

We can reset the keypad and program a fresh code during a quick service visit.

Can you program it for me?

Yes — we supply genuine LiftMaster accessories and program them to your opener, either in one of our service visits or bundled with any repair or installation. Call 954-799-9787.
