Place a plastic opening tool along the seam of the front plate and back plate. Run the opening tool along the seam while prying slightly in order to pop the plastic clips away from the front plate.

Once one or two clips have popped away you may begin to use your free hand to apply additional pressure while continuing to apply prying pressure as well with the opening tool.

Apply constant but controlled pressure while separating the front from the back. Damage may occur if using excessive pressure while separating the plates along the seam.
