Remove the five black screws from the back of the controller using a Phillips #00 screwdriver.

Place a finger between the faceplate and the rest of the controller and pull each half of the controller apart to separate them.

Don't use too much pressure when prying open the controller as you may damage the white ribbon cable connecting both halves.

The iFixit Mako Driver (screwdriver that also comes in the Pro Tech Toolkits) is too thick to properly reach the 2 top-middle screws. The middle top-left screw can only be reached at a slight angle, while the middle top-right is near-impossible to reach without the use of the Flex Extension, or deforming the plastic a little bit.
