With World of Warcraft’s Dungeon finder, is it necessary to have the keys?

For example, the quest chain for the arcatraz, what if you just select arcatraz in the dungeon finder. Good then?

You are required to have the keys for dungeons that cannot be accessed without them, like BC heroics. However, The Arcatraz can be unlocked from outside by any group member with a key, and does not specifically require YOU to have a key to access.
