Hi, I found that Lithium Batteries work better in the cold weather than Alkalines. The only gotya is price. It cost me $10 for four AAA batteries. I am using them in the outside sensors this year. Last year I had to replace the Alkaline batteries a couple of times during the winter. I also occasionally bring in a remote sensor if I'm having problems and place it on the hot water baseboard heat units in the house. This drives away any internal condensation that may be causing problems. (Don't try on electric baseboard heat - it may get too hot). Usually one day on the heat vent is plenty to dry out the unit.

I have Craftsman opener which is made by Chamberlain. Go to the Chamberlain.com website for the support phone number. I called them with a problem and they were very helpful.

I realize this is an old post but I am having the same problem, hoping someone can help. I replaced the battery because I was having to push the button several times to get it to work. After I put in a fresh battery (not upside down) it won't work at all. So I went to Sears and bought a new remote today (yes the correct model) and it won't program.

My suggestion is you trade a few bucks for a fast upgrade that takes the old remote out of the picture. You can buy a new receiver at most home centers that has all the high security feature, comes with one or two remotes, and will work with the transmitters built into many newer vehicles. You wire it into the old power head as if it were a wall button. It's neat, easy, secure, and fairly cheap. Worth considering provided the power head is in good shape. Since it just wires in like the wall switch, any brand will work. One example is Chamberlain Universal Radio Control Replacement Kit, $57 at Lowes. Note: Safety regs get stricter all the time. Newer units may have less range by design, but still work.
