2 x LiftMaster 800 garage door openers

[Michael]

I have two LiftMaster 800 Garage Doors and a Chamberlain Gate opener. These all work correctly on the old 3 button remote. I bought some additional remotes (but they are 4 button). When I set them up on the garage doors pressing the orange button and then the small button on the remote, either small button now opens both doors. (not what I intended   ). Could the new remotes be faulty or have I done something wrong?

Hi Richard,

Do you know the model number of the remotes you purchased? Are they the TX4UNIS or TX4UNIF by any chance?
