Locate the two small oval depressions in the keyboard fascia, just below either Ctrl key.

Using a flat screwdriver or narrow spudger in the depressions, slide the fascia up towards the hinges about 3mm (0.1 inches). The top edge slips beneath the bezel.

This exposes five Phillips screw heads, located in the 3rd and 5th rows of the key area. Remove them.
