I have an attached two car garage. Both doors have Craftsman operators. I also have two Skylink mod G6KR remote openers for each door. The interior push buttons for the operators and the Skylinks are located at the back of the garage just next to the house entrance opposite from bay doors. The Skylinks remote keypads are located just outside the bay doors as expected to allow remote entry. The antennae for the Skylinks are about 7” long and are about 20 feet from the keypads located outside the bay doors. The Skylinks take two CR2032 coin batteries each. Here’s the problem, the key pads work intermittently. Not sure if it’s the temperature or what. But there seems to no real pattern. One will work when the other may not. Or both won’t work or both will. I think I get better action when the weather is a typical summer day. So winter I expect more problems. But even in winter they may work satisfactory. I also think it’s the signal from the antennae that don’t get a clear signal. Can you just strip the antenna wire and add more to it? I'm thinking too much metal is affecting the signal.

But if the batteries were the problem I would not expect them to work at all after a few weeks. But these batteries show a good charge and do work some of the time. Even when moths old.
