I have an automatic garage door operated by remote control. I have 3
remotes , two of which are Hormins, the manufacturer, the other an
independent remote. Mostly they work fine, but after dark sometimes they
fail, this is a fairly recent problem, to operate the door, unless my wife
of I get out of the car and move close to the garage doors. Any
suggestions as to what the problem may be and a possible d=cure? The
batteries in the remotes have been replaced to no avail.

Looks like the receiver is going electronically deafer
and the after dark is most likely just a temperature effect.
