Sort of. It still works with the door button, but I have two remotes

Chamberlin/liftmaster and the remote is 373LM. Suggestions?

Presumably, you have just ONE door? I.e., don't have a second
opener on which you can test the remote?

no second opener



Is that the remote that handles *3* doors?

yes


If so, have you tried programming buttons other than the "first"?
I.e., in case the actual "button" has worn out?

yes



Are you getting any tactile feedback from the button? I.e.,
does it have the same "click" and "feel" as the others?

yes


Have you tried erasing all the codes from the opener and then
trying to program? I.e., is the problem in the remote or in
the opener?

erased all codes and then tried the "learn" process again with no luck



Does the opener do ANYTHING when you attempt the programming
sequence? I.e., does it "see" that you've activated the remote
(even if it is rejecting the programming operation)?

I get no light flash or click


Is the antenna wire visible in the opener?

yes, tried several times moving it around with no improvement
