Place the keyboard on a firm surface with the KEYS FACING DOWN! This is important. Some keyboards have floating keys and opening it with the keys facing up could put you in a bind when you put it back together.

Inside you will find about 3 more screws holding a ribbon cable to a board. Take note the orientation of the rubber grommet and metal bar. This is how it will need to go back together. Remover those screws and the electronics attached.

The ribbon cable connects to a larger sheet that acts as a capacitive touch button thing... either way, the name is less important than you wiping this down with rubbing alcohol.
