in the demo the security door lockdown isn't active, it's for latter in the game. The terminals that are locked on the crew members quarters are in the full game as lore drops and story, in the demo they are nothing. The doctor's office terminal code can be found in his office if you explore his office more. Particularly the painting on the wall.
