Do these woek with Liftmaster Formula 1?

Liftmaster has an odd way of matching remotes to existing door openers. They are color coded. Look at the back of your garage door opener (the power unit) it should have a round button and two arrow or triangle shaped buttons. These buttons are color coded. Usually yellow or purple. The811LM remote controls work with the yellow buttons and yellow antenna wire. I hope this helps.

Are these compatable with the liftmaster la400 ul gate openers?

I do not know. Sorry. I got the name & model number off if the gate & then searched that info on Amazon.

does 811lm is the same as 891lm?

Reliable

It works!!!! Yes it took 1min to program and it works. Just costs 2.5x what it cost me a couple of years ago when I bought some extra just like everything else I guess.

Good product.

Purchased to replace existing gate entry remotes that lasted 7 years after heavy. Easy to program and working strong after two months of daily use.

Easy to set up and works as described

This item was used to open a Liftmaster farm gate controlled by solar powered batteries. Worked as described and easy to set up. However, for the amount of material used to manufacture this device, it was far too expensive. Nevertheless I'm obliged to order two more for members of the family :((
