Forum:Fallout: New Vegas Vault 22 Issues *Please Help*

Guys, I posted this earlier, but I think something happened to it, or I put it in the wrong location. But regardless, I really need someones help.

Tonight I decided to go into Vault 22 and go through the entire thing. When you go into the Vault from the wastes, you enter a subsection that has some green plants, and a bed to sleep on. To get into the actual Vault you need to go through another door. So I went through this door, and spent 3.5 hours inside doing everything, covering every part.

When I went to leave the vault, I get to the first door that you have to go through to get to the are with the bed on the floor that is the room that leads you out. Here is the thing... When I try to go through that first door, It says 'Need a Key to get through, you cannot pick this lock' (somewhere along these lines).

I've looked EVERYWHERE, I've done EVERYTHING.... I'm all out of ideas.. please help me. I do not want to revert to an earlier save and waste 3.5 hours of time

Any help would be greatly appreciated.

Thanks a bunch to all.

Respectfully,

Me
