THE UNOFFICIAL FIELD GUIDE / ROBLOX HORROR
You wake up in a sealed room. To get out you need four keys and one four-digit code, pulled out of a corridor network that is built to look the same in every direction — while something hunts you.

Read this before any other guide. Published elevator codes contradict each other.
Because the rule behind the code is not established, a number copied from someone else's run is not a reliable answer for yours. What does carry over is method: the search order, the landmarks, and which furniture can hold a key. So read your own code off the block, and write it down.
Looking for one part? Jump to the MONOCHROME key locations, the MONOCHROME door code (elevator code), or the MONOCHROME map and routes.
The run begins with the exit sealed. Pry the planks off the boarded "DO NOT ENTER" door to open the way down. Hold E to interact.
Below is a network of abandoned corridors that look deliberately similar to each other. The difficulty here is repetition rather than size: one corridor is hard to tell from the next.
Keys are found by searching furniture — dressers and drawers — rather than lying in the open. Open every drawer you pass. Do not assume a room is empty because the first dresser was.
The elevator code is physically printed on a block in the maze area. You have to read it in your own run. Write it down the moment you see it. Backtracking through the corridors to re-read it is avoidable work.
The deadbolt panel sits beside the elevator. Each key you deliver turns one indicator light green. Four lights must be green before the elevator will respond.
With all four lights green, punch the four-digit number into the keypad and press Open Elevator to escape.
Record the code and progress you see in this run. Saved in your browser only.
Browser storage is unavailable. Your notes will last only while this page stays open.
Tap a key once you have carried it to the lock panel.
Write it down the moment you see it on the block, so you never have to re-walk the maze to re-read it.
Corridors repeat, so the hard part is remembering where you have already been. Name rooms by their landmark — "stairs junction", "closet corner", "double dresser".
Nothing logged yet.
Search for the MONOCHROME elevator code and you will find confident, specific numbers. The problem is that they disagree with each other, and the guides that published them have already had to walk them back.
Published walkthroughs report conflicting elevator codes. Confirmed
Two different four-digit values circulate widely (5343 and 0849). One guide published a separate article asking whether 5343 still works after a game update — the author stopped trusting their own number.

What determines the code — the individual run, the server, or the game version — has not been established. Unverified
No source we found documents the rule. Conflicting published values prove that guides disagree; on their own they do not distinguish a per-run value from a per-update one. Treat "random every run" as unproven rather than established.
No source we found establishes this. Listed so you know the gap exists, not as a finding.
Permanently fixed key rooms have not been confirmed. Reported
Community wikis state that permanent individual key rooms are not confirmed, and describe keys as found by searching furniture rather than at set coordinates. That is an absence of confirmation — not proof that key placement is randomised.

The code is printed on a block inside the maze and read during play. Reported
Multiple walkthroughs describe reading a four-digit number physically printed on a block, rather than receiving it from a menu or a fixed plaque by the elevator.

This is why this site does not print a number at the top of the page. What carries over between runs is method: where to look, what furniture can hold a key, and how to navigate corridors that are designed to disorient you. How to find your own code →
Press E to hide inside a closet when the monster is nearby. Plan your route so you are never far from one.
Corridors are built to look alike. Random sprinting burns time and puts you in unsearched territory with no exit plan. Move between known landmarks instead.
Interaction is a single key. If something looks like it opens, it probably does.
The four-digit code people search as the "door code" is the one you type into the keypad that opens the elevator — the game has one code, not several. Nobody can hand you a reliable number. Published guides list conflicting values (5343 and 0849 both circulate), and one guide published a follow-up asking whether the older number still works after an update. What sets the code — the run, the server, or the game version — has not been established by any source we found. It is printed on a block inside the maze, so read it during your own run.
Community wikis state that permanent individual key rooms are not confirmed — which means nobody has published reliable fixed locations, not that placement is proven to be random. Keys are found by searching furniture (dressers and drawers) in the corridor network below the boarded door, so a systematic search order beats a list of coordinates.
Four. Each one delivered to the lock panel beside the elevator turns one indicator light green. All four must be green before the keypad will open the elevator.
Press E to hide inside closets when it is close. Because the corridors look alike, the practical defence is route knowledge — always know where your nearest closet and nearest staircase are.
No. The 2026-10-02 update retitled the game "{ Pt. 2 } MONOCHROME", so the creator's second part appears to be live; a further update on 2026-10-16 renamed it again to "MONOCHROME🎃", and it is still described as early development. The official goal is unchanged: four keys and one code. What these updates changed — areas, key spots, the code — is not documented by any source we checked, and the guides we cite were last revised before both of them. Expect mechanics, including the code, to change between updates.
