How do you get out of Vault 92 in Fallout 3

All you need to do to get out of Vault 92 is go out the way you came. There is a glitch however where is you close the door then go inside the vault, if the door closes while you are in the vault you are stuck there forever. There is no other way out unless you can glitch your way out. But if the door is still open just go back the way that you came.
