Magic keyboard UP key broken

Hi, I have this keyboard. The UP key stopped working. I took of the keycap and the switch and also the small rubber dome. It's still not working. I can see some discoloration under it, like if it was burned.

Do you know what could it be? No matter what I do with a screwdriver it doesn't work. The DOWN key works when I slightly press it.

Is there any chance of fixing it, or I better keep it as a keycap donor for identical keyboards?

Doesnโ€™t look good here๐Ÿ˜ 

The metal clip is bent and it does look like there was a short (burnt part) did you try lifting the keycap a bit to aggressively here?

Apple treats keyboards and other input devices as throwaway as such they donโ€™t offer parts and the construction is not conducive for repairability. Even still there are parts houses which do carry some parts in the UK there is a good one TheBookYard if you are on that side of the pond give them a try.

Sure, I opened it too strong, but this keyboard was broken for a year or so, it was just in my drawer. I was just very interested in what could have happened to that UP key.

But how is this supposed to work? I mean when I press the rubber dome on the DOWN key, it works. What is touching what? All I see is a metal and a transparent foil on top.

The rubber dome has a carbon disk which shorts across the two pads completing the circuit which in turn is converted into a signal the systems logic can interpret as that keys action.
