We have a Craftsman security+ model 139.53684, keypad plus two transmitters. My transmitter quit working and mom replaced a battery in my transmitter and worked for two days. Quit working again and reprogrammed transmitter but accidently deleted all others from opener I have tried twice to get the keypad and two transmitters reprogramed but to no avail. we are only able to get the keypad or one transmitter to work.
I Have unplugged the opener from the electrical outlet and plugged it back in which is what I read on a website for similar problems where they called it a (HARD RESET) and tried reprogramming the keypad and transmitters, but still can get only to work at a time.
Any advice? Need new Transmitters? New Opener? Some similar problems like ours on other websites said it could be a problem the logic board not accepting transmitters/keypads. Could that be the problem? would like to resolve this problem.
