The special warehouse keys are in the treasure chests. So for example, in a treasure chest in warehouse 1 is the special key to unlock warehouse 2. You can not get into the next warehouse till you find the key. So even if you get all the good items from a warehouse, you might get stuck trying to unlock the next one.
