What key do you need to open this door?

Question

This is located on The Throne of Deceit (Bazir) i want to know if there is a mechanism to open this door or is there a specific key that will open it 

Answer 1

You need Key 5100

This key was part of the first draft of The Pits of Inferno Quest, but it was not obtainable in game anymore when the quest was released to players. It spawned in the maze here, and was used to open the door here. Passing the door is not necessary to go through the maze, but it can still be opened by pulling one of the levers in there.
