The Atomic Heart station master door code puzzle requires you to find the button code for the combination lock blocking the station master’s office. It’s a puzzle lock that you must solve early in the Vavilov Complex while on your search for Petrov as part of the “Wanted Dead or Alive: Victor Petrov” mission. After you’ve found the lock on the station master's office, you can speak to a nearby Chatty Corpse, who will tell you that the now dead station master had the schematic for the Atomic Heart lock, so you'll need to look for him to get the combination. Here’s where you can find the combination lock code for the station master's office in Atomic Heart.
