Locate the cord connected to the motherboard on the upper left and the ribbon strip connected to the motherboard on the bottom middle of the silver keyboard housing.

Remove the cord, on the upper left of the keyboard housing, from the connection point using the plastic opening tool. Place the plastic opening tool on one end of the white plastic piece. Pull on the edge of the piece to remove it from the connection housing.

Disconnect the ribbon from the connection housing by prying both ends of the cream plastic piece away from the ribbon.

Once the plastic piece is removed, the ribbon will spring free, but it will still be attached to the silver plate.
