I think they mean that the first door in the entire game won't open at all. I had the same issue. I tried changing my keybinds, but I couldn't get out of the configuration menu.
You mean the door in the very first room in the game start, did you tried to loot a lock pick on the right side of the room?
If you have properly looted and still couldn't be able to unlock the door, it is a bug, but if you didn't, please try it and inform me.
Tried it, found the lock pick for the first time, and it worked. Thanks!
