CHAPTER 03 / UNLOCK THE EXIT
This is the four-digit code for the keypad that opens the elevator — what most players call the MONOCHROME door code. The game has one code, not a separate one per door.
Short answer: nobody can give you the number. Not this site, not the guide ranking above it, not an AI summary. Here is the evidence, and what to do instead.
Read the block in your own run. Save all four digits. Deliver all four keys.
Multiple walkthroughs describe the same mechanism: the four-digit number is physically printed on a block inside the maze area. You do not receive it from a menu, a chat message or a fixed plaque by the elevator. You have to walk far enough into the corridor network to see it with your own eyes, in your own run.
That single fact is what makes every "the code is 5343" headline unreliable. If the number were global and permanent, a guide would not need to hedge about updates — and two guides would not be publishing different digits.
The moment you see it, write it down. An avoidable way to lose a finished run is reading the block, continuing to explore, getting chased, and then being unsure whether the third digit was a 3 or an 8. Use the field below — it stays in your browser.
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.
The code alone does not open anything. The sequence is:
Each key carried to the lock panel beside the elevator turns one indicator light green.
The keypad will not finish the job while a deadbolt is still locked.
If nothing happens, check the deadbolt lights before you doubt the code.
Check in this order. First the lights: a run with three of four deadbolts open looks identical at the keypad to a run with a wrong code, so rule that out before you doubt your digits. Then re-read the digits you could have misread: 3 and 8, 0 and 6, 1 and 7. Only then consider that the number itself may not apply to your run.
Two different four-digit codes circulate widely in MONOCHROME walkthroughs: 5343 and 0849. They cannot both be universal. One published guide went as far as writing a separate article asking whether 5343 still works after a game update — which tells you the author themselves stopped trusting it.
MONOCHROME is still in active development. The Roblox page is now titled “MONOCHROME🎃” and was last updated on 2026-10-16. An earlier update on 2026-10-02 retitled it “{ Pt. 2 } MONOCHROME”, so the creator's second part appears to have arrived — and the guides that published these codes were last revised before both updates. Mechanics that a guide verified in early September are not guaranteed to hold now.

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.
