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?

Will this work for the 841LM?

Hi this is a Ideal for gated communities or commercial applications requiring a large number of remotes for a common entrance. Compatible only with Security+ 2.0® commercial receivers and operators. Thank you.
