Well, in any case, I got it to work! Without your advice I would have never tried to fix it. The fix was easy once I realized how the stabilizer worked.
It's probably different for other keyboards but all I had to do was click back into place (although it took me forever to figure out the original positioning).
I had original though the metal strip somehow was supposed to push the spacebar back up but that was completely wrong, mine is laying on the back of the keyboard, locked into place.
