Hey Michael,
From what I have seen it is a pretty in depth teardown. I believe that the motherboard and heatsinks will all need to be removed before being able to get to the keyboard. I know there are a couple of replacement guides for other things regarding the Dominator, on this site, just not for the keyboard. [br]

Hope this helps.
