Craftsman 1/2 hp, model 139.53962srt1
I am having issues with my Craftsman Â½ hp garage door opener. The unit is about 5 years old. My garage door openers stopped working last week. I replaced the batteries and attempted to open the door but it still did not work, so i went and bought a new opener (craftsman 953879) still didn't work from the remotes. I erased all the codes, as that was the only thing left i could think of doing. I found the original manual and it said to check the "lock-out" button, which someone had had pushed, but by me erasing everything in memory, i can't get the (2) remotes and key less entry pad to work. I have attempted to reprogram the two garage door openers and the key less entry pad but am only able to get one of the openers to work. If I try and reprogram the key less, it just flashes, if i go on top of the motor and put it into learn mode, the key less works, but the one remote that was working stops and i can not ever get (2) remotes to work at same time.
Any help will be appreciated.
