Doors players have a substantial list of listed promo codes to try in October 2026. The rewards are Knobs and Stardust, two currencies used in the Roblox survival game. Knobs are especially useful before a run: they can be spent in the pre-game store on survival equipment including lockpicks, vitamins and a flashlight.

That makes codes more than a bit of housekeeping. Doors challenges players to press through dangerous, eerie corridors and open as many doors as possible. Progress through doors earns Knobs naturally, but starting with extra currency can give a player access to supplies that may help a run last longer. A lockpick or flashlight is not a guarantee of survival, of course, but it can be a practical resource to have rather than a decorative number sitting in a virtual wallet.

Promo codes can expire without a clearly stated schedule. The sensible approach is to redeem working codes promptly, especially the larger Knob rewards, and avoid treating a code list as permanent. Below are the currently listed codes and a redemption walkthrough for keyboard, console and mobile players.

How to redeem codes in Doors

  1. Open Doors in Roblox and look at the bottom menu bar.
  2. Select the button marked with three asterisks to reach the codes screen. Alternatively, open a menu and scroll to its end.
  3. Type a code into the Enter Code Here box.
  4. Claim it using Enter on keyboard, A on Xbox, X on PlayStation, or the on-screen touch control on mobile.

Case is not the obstacle here: access granted and ACCESS GRANTED should be treated the same. Spaces are more important. Several active entries contain spaces, including JUMP OVER THE BRICK, BIJUU MIKE and CHEDDAR BALLS. A trailing blank space can stop a valid code from working, so manually typed entries deserve a quick check before being dismissed as expired.

What the rewards mean for a run

Knobs are the practical, run-preparation currency in this list. They can be used during the game’s pre-game shopping phase for items intended to improve a player’s odds in the corridors. The supplied examples are lockpicks and vitamins, while a flashlight is also identified as useful survival equipment. Players also gain Knobs by advancing through doors, so code rewards can supplement normal progression rather than replace it.

There is a simple compounding advantage in redeeming Knob codes before playing. Additional starting currency can be spent on useful supplies; making it farther through a run can mean passing more doors; and passing more doors earns more Knobs. It is not an infinite money machine, just a helpful starting cushion in a game where a short run can leave little room to build resources.

Stardust is the other reward type distributed by the listed codes. The available information identifies it as one of Doors’ two primary currencies, but does not detail its individual uses. That distinction matters: players should not assume Stardust buys the same pre-game gear as Knobs simply because both arrive from promo redemption. Claim it while available, but plan pre-run purchases around the Knobs balance and the items known to use it.

A quick priority order for code redemption

If entering every code feels like a lot of menu work, begin with the largest rewards. The two 150-Knob entries, ACCESS GRANTED and ACCESS DENIED, are the biggest individual Knob grants on this list. LAZYDEVS, 3RD and SCREECHSUCKS follow with 50, 33 and 25 Knobs respectively.

For Stardust, PROTOCOL is the standout at 20, followed by REPRESSED at 10 and CRUSADERS at five. The three one-Stardust codes are still worth claiming if they remain valid, but they can wait until the more valuable entries have been checked.

That ordering is an efficiency suggestion, not a claim that smaller codes are unimportant. Small rewards add up, particularly when the code screen is already open. The key is to avoid overlooking the high-value entries while typing through a long sequence of five-Knob rewards.

Codes that are no longer active

The following codes are listed as expired and should not be expected to grant rewards: TEST, 100MVISITS, LOOKBEHINDYOU, PSST, 500MVISITS, ONEBILLIONVISITS, SORRYFORDELAY, SORRYBOUTTHAT, 2BILLIONVISITS, THREE, 4B, THEHUNT, 5B, SIX2025, 1000, 777, GRACE, NO_DATA and FE4R_RBX.

GULLIBLE is also not a reward code; it is described as a prank and provides nothing. It is a useful reminder that a code-like word circulating among players is not necessarily a working promotion.

Older expired offers included combinations of Knobs, Revives and Knob Boosts. A Revive is a distinct reward from currency, while a Knob Boost is likewise separate from the upfront Knob amount. Those rewards appeared on past codes such as ONEBILLIONVISITS, 2BILLIONVISITS and THREE, but they are not part of the active-code list above. Players returning after a break should therefore avoid relying on an older guide that promises those extras.

Why code lists need a little skepticism

Game-code coverage is inherently time-sensitive. A code can be active at the time a list is assembled and unavailable later, often without a public countdown. The cleanest way to handle an unsuccessful attempt is to check the basics first: use the exact spelling, retain any spaces within the code, remove accidental spaces at the end, and make sure the code has not already been claimed on that account. If it still fails, expiration is a reasonable possibility.

It is also worth separating promo codes from general Roblox avatar promotions. Doors codes deal with rewards inside Doors, specifically Knobs and Stardust in the currently active list. They are not described as account-wide avatar items usable across every Roblox experience.
