I'm stuck at Olympus heights and need a code for a door. And there's no hack option! I thought I listened well to the tapes i found but apparently note or I'm missing something!

The code for the door to the elevator? It is in a diary which has a title pertaining to a lock or code or something.

Yeah, the elevator? If I remember right, there should be a diary on the top floor of the living quarters by a corpse. I THINK that's the one with the code. I could be wrong though....

I think I recall it being 5744. Give that a shot.

yeah 5744

I always hacked all the doors.

I always hacked all the doors.

He's asking about the door that leads to the final battle. You can't hack it.

I think 5744. It was in a message.

You can't hack the very first door either.
