Last updated: May 10, 2026. Covers all active codes, confirmed secret rooms, achievements, and community-discovered secrets as of The Great Outdoors update and the upcoming Archives Update (expected May/June 2026).
Overview
DOORS by LSPLASH and Redibles is one of the most content-rich horror games on Roblox, packed with codes, secret rooms, easter eggs, hidden achievements, and developer references that many players never discover. Whether you’re trying to maximize your free Knobs through codes, find every secret room, or uncover the hidden lore scattered throughout The Hotel and The Mines, this guide has everything you need.
Unlike many Roblox games, DOORS rewards thorough exploration and attention to detail. The developers have hidden dozens of secrets across multiple floors, and the community continues to discover new ones years after the game’s launch. For a complete walkthrough of every floor, see our DOORS Beginner Guide.
Active Codes in DOORS (May 2026)

How to Redeem Codes
| Step | Action |
|---|---|
| 1 | Launch DOORS on Roblox and enter the Lobby |
| 2 | Walk to or look for the Shop area in the Lobby |
| 3 | Find the text input box (code redemption field) in the Shop menu |
| 4 | Type the code exactly as shown — codes are case-sensitive |
| 5 | Click Redeem or press Enter |
| 6 | A confirmation message will appear showing your reward (Knobs, Stardust, etc.) |
Current Working Codes
| Code | Reward | Type | Notes |
