you need to be revered with some factions. However, for shattered halls u also need to kill an orc in shadowmoon valley. I think he is some kind of black smith around black temple. I think he drops an item which gives quest to make key.
This is only for the dungeon key. You can be let in with the correct faction reputation and 'heroic key' purchased.
