Lift up and loosen the metallic silver trim on the perimeter of the phone using a nylon spudger.

Carefully remove the gray mid-plate with the spudger.

Take extra caution to not destroy the QWERTY keyboard, which lies directly behind the mid-plate. Do not slide open the phone at this time.

The mid-plate should be completely removed from the keyboard and separated from the device.

At this point, you may remove the original QWERTY keyboard and install a replacement keyboard. Installation is the reverse of removal.
