I would also like to mention, yes i do have the Diamond Claw, its bugging, its common. but i do not see any solution to fixing this so far.If anyone knows any other way to fix this I would appreciate the help very much. I am playing on the Xbox360 by the way.
This bug has ruined the game for me. I honestly have not touched Skyrim for over 2 weeks because of this.
EDIT: This has been solved for me and a few others thanks to OverBleed's post below, however i would like to note that just because people have found their way around this bug does not mean it does not need to be fixed.

Well 3 hours later of trying anything i thought of this worked....
1. go to the door and mess up the code, dont use the key
2. leave the area so it loads in another part of the dungon
3. save your game
4. exit out of the game or reload it or goto dash board
5. relaod and go back to door, do not use the key yet
6. align door rings in the right order then use claw door key
i have this for 360 but i hope this works for you if you have something else
