Ok so i have the same issues many people seem to be having with dead money.

It seems that they messed something up in the latest fo:nv update so that It now permanently locks the abandoned BOS bunker with no way to get inside (that I know of) other than unpatching / uninstalling and reinstalling the game each time you wish to use the dlc entrance to get in or out of Sierra Madre...

Now it's been rumored that the BOS safehouse key could open the abandoned BOS bunker but I don't know for sure yet this might not be true, it needs confirmation, I'm gonna try now on a new save with the latest update and the DLC entrance properly locked and come back with the safehouse key and see if it works...

Can anyone confirm if the BOS SH key works before I go through with all the bothersomeness or is there another known way to get inside the dlc that I have missed?.. (Again, on ps3)

Thanks in advance guys, I'll be checking in every now and then while I'm doing these tedious tasks for the brotherhood..

Yea and uh.. Thanks in advance for any helpful answers!
