Cannot level bed - keypad isn’t working

I am re-levelling the bed after moving the printer. Was finding that it would seem to be fairly level and then suddenly one corner would be super tight to the paper so would have to keep adjusting, but then suddenly the nozzle was pressed in to the print bed and we could not get it to raise up at all. We have tried increasing the Z axis but it doesn’t move at all.
Went in to the other settings and finally got the nozzle off the bed but now we cannot use the levelling keypads at all. I can press any corner number for Aux level and nothing happens. We try Auto level and it will tap down once and then quit. At a loss as to what to do.
