Can anyone please tell me how to get the right side sliding door lock assembly off. I have removed the inner panel, taken off the handle and the torx behind the hinged side of the handle and the 3 screws holding the lock mechanism to the inner door, but seems to be holding on at child lock, but can't figure out how to disconnect/remove the child lock so I can pull the lock assembly out.

Any help would be appreciated or a how to or service manual extract.
