The keyboard is held by several clamps located at the top of the keyboard. Use a paperclip or pryer tool and push in all of these clamps.

Carefully pry out the keyboard. The bottom part of the keyboard might stick on, so be gentle. Also keep in mind that the ribbon cable of the keyboard (which is under the keyboard) is still attached to the motherboard. Don't remove it yet!

Gently lift up the keyboard as seen in the third picture and go to the next step. Again, don't remove the keyboard yet, otherwise you might damage/tear apart the ribbon cable!
