So mine has only two screws. The pcb was attached to the upper left one (the other one on the left has a small plastic insert so you cannot put a screw there). I found the other screw and the metal part it screws into it in the case as shown here:

I presume it goes it the emply round cylinder at the bottom. That would make 5 screw holes. Problem is, the metal cylinder doesn't slide into it. It doesn't fit.

Looks like a part broke off? Or not?

Sixty, can you check if that's were it goes and if the metal cylinder should slide all the way to the bottom of the board, or whether a small plastic part broke off?
Note that the keyboard was packed in a plastic sleeve and I found no other parts.
