Step 2

Use the Phillips screwdriver to remove all twelve 2.6 mm screws from the bottom cover.
Carefully remove the top lid, but do not separate the bottom cover from the lid as the two pieces are connected internally by a thin ribbon cable about an inch wide.

Step 3

Set the keyboard in a similar position in the picture, using a paperweight to hold the cover in place. I used the aluminum foil tape you need for the project

Step 4

Find your section of the keyboard and remove the 4 screws holding the keys in place. Then slowly lift the top keys away from the board.

Step 5

Each key correlates to one of these buttons or "carbon boots" which typically has lost its conductivity. Identify which boots/buttons are faulty and use the screwdriver to peel it back, exposing the circuitry under said button, which touches the board when you hit a key.
