Garage door remote cold temperature

I've got an older liftmaster garage door opener, in my attached and insulated but not heated garage (it's typically 10c warmer inside then outside). It does not have the safety eye sensors for the door.

When the temperatures get about -20c outside the remotes (wireless keypad and homelink-hardwired factory opener in dodge truck) will operate the door about 50% of the time. In addition, it seems to not operate the door a 2nd time in succession. (eg. drive up to door, opens door properly, pull into garage, will not shut the door when parked in garage)

When the temperature gets to -30c outside the remotes just do not work, even if I try to open the door, while the vehicle is sitting in the garage directly below the opener.

So far I've removed the 100w bulb that shouldn't have been in there, and put dielectric grease in the electrical connections. This hasn't changed anything.

The hardwired remote works every time and the opener works fine all summer.

Any ideas of what to try next?

Welcome to the forums!

I suspect the battery is failing because of the cold. You might try bringing the remote inside for a bit and then see if it works.

I thought that too, but the truck opener is hardwired in...there are no batteries for it
