My GDO transmitters have stopped working, I have replaced the batteries and still no dice. There is absolutely nothing user serviceable inside(not even a way to reprogram) except the battery, which is one of those 2032 coin cells. It is a Chamberlain Liftmaster circa 4/2000. Don't have the cash to replace the unit, and do not understand why the remotes started to work intermittently, and then stopped other than the battery died. Like I said, I have replaced the battery and they still don't work.
