Remote Issue

Two door garage.  Has worked without issues for 13 years.  One door now works fine with no issues.  Other door works fine with no issues when wall panel is used.  No need to hold button to close door.  When remote is used door will open but not close.  Can't even stop door once it has started opening.  Put new battery in remote, no change.  Two remotes both have exact same problem.

I am guessing it must be something to do with the antenna going bad or being partially blocked, but I can't figure it out.  Any thoughts?
