Replaced remotes and programmed existing wired keypad 6 months ago with no issues. Sensors show one with constant XXXXX XXght and other with constant green light which I've found to be the normal working condition.
I will try these steps. I should have noted that the random opening doesn't occur frequently, its only happened 3x in 2 weeks so it's going to be somewhat difficult to determine which of these steps work(ed). I'll get back to you with what I find.
