finished the dead money xpac and get to the end, got all my stuff back and was tryin to get back to the wasteland true the door in the celling and it says i need a key, now i wasnt given a key at any point to open this door and i have tried to reload the game several times, have also played thru the Father E. encounter a few times and still nothing, anything that can be done?

Yeah im dealing with the same exact problem i dont know why that happened
