Since I don't use the garage for a car, I don't need to open it very
often. But when I do, I have to push the button on the remote anywhere
up to a dozen times before the door opens.

I barely understood your post or the reply, but what happens if you
push the remote once (or maybe twice) and wait the same length of time
that it would take you to push the button those dozen times?

IOW, is it responding to the first push but taking forever to do it,
or to the last push?

Once it's open, it will close
and open first time every time. Until I close the door and leave it
alone for a few days. Then it's back to the same old tricks.
