3. The eight smaller keys need to be levered from the bottom up.

4. The scissor mechanism of the eight small keys are obstructing the underlying screws.
5. By using again an opening tool or opening pick these can be snapped off easily.
6. When reassembling be sure to place them in with the correct side facing upwards.

11. Now you can pull the flex cables out and remove the keyboard completely.

15. Disconnect the battery connector from the DSP board.
16. Unscrew the two Phillips #00 screws holding the board down.
