Four screws (two long, two short!) hold the case together, as well as some fragile plastic clips. One look at the keyboard shows that it is basically not serviceable. The keyboard matrix is a rigid PCB which has been thermally welded to the plastic keyboard frame. I guess you can open it, but it will be a pain to secure again.
