Craftsman remote stopped working after replacing battery
I have a craftsman 1/2 HP garage door the remote model # is 139.53879 visor clip the other 139.53859 key chain both are 3 button controls.
I replaced the battery in the visor clip and now I can not program it. The key chain one works fine. I have done several things to try and fix this:
Bought new remote Still NO luck
cleared all memory in opener and remotes
no new electric items have been plugged in recently and now new wi-fi in the house.
I can program the key chain remote to work with both doors.
Please help! I have been all over the internet for help....
