Sears Garage Door Keypads and Remote Don't Work?

I have 2 separate units for my 2 garage doors. When we both left the house I closed my side with the car homelink (which worked perfectly). My husband closed his with the handheld remote which also worked perfectly. When he returned home before me, he hit his remote and it did not work. He tried the button for my side and that did not work either. Then he tried to get in through both of the keypads and neither one on either side worked.

When I came home my homelink didn't work. What could cause everything to fail at the same time? When we tried to reprogram the keypad on my side it would not work. We tried to reprogram the remote on the one side and it started to open both doors. Then it wouldn't open either door and then it only opened my door. Then it went back to opening both doors simultaneously and then randomly stopped. We never even got to the learn button on the second unit because nothing made any sense. The Homelink in my car won't reprogram and the keypad won't either? What can we do? I have tried to reprogram everything based on the instructions that have always previously worked.
