I'm way behind times on this one . But having same problem ! The combination IS listed in the walkthrough, but you can't use it, because the actual Lock will Not come up. So you can't enter the combo. Evidently, you have to actually find the combo first, which of course, makes sense. However, there;s nothing the wt about it, at least that I saw. I scrolled back quite a bit looking. Very frustrating.
