Build A Blue Lock Squad Codes

How to redeem codes

  1. Join The LockerRoom group on Roblox first — codes will not redeem until you are a member.
  2. Launch Build A Blue Lock Squad and wait for the lobby to finish loading.
  3. Click the Settings button in the bottom-left corner of the screen.
  4. Type or paste the code into the Enter Code box exactly as written — several are mixed case, such as OneThousandCCU.
  5. Press Redeem and confirm your reroll count went up before entering the next code.

Code freshness policy

  • A code is only marked working when at least three independent trackers list it as working in the same week.
  • When trackers disagree, the code is marked unverified and the disagreement is stated in its note. It still costs nothing to try.
  • Expired codes stay on the page rather than being deleted, so you can see what has already been tried.
  • Reward amounts are cross-checked too. Where sources give different numbers, the majority figure is shown and the conflict is noted.

FAQ

Codes FAQ

Why do my codes keep failing?

The most common cause is not being in The LockerRoom Roblox group — the game checks membership before redeeming. After that, check capitalisation: codes like OneThousandCCU and SpiriXSolos use mixed case and will not work typed in all caps.

How do I get free rerolls without a code?

Like the game, add it to your favourites, and join The LockerRoom group, then walk over to Sendou in the lobby. He checks all three and hands over ten rerolls. This is a one-time reward, separate from codes.

Why are fewer codes listed here than on other sites?

Most code pages copy from one another, so one mistake spreads across a dozen sites and stays there for weeks. Codes here are only marked working when several trackers independently agree, and anything disputed is labelled rather than quietly listed as working.

Where do new codes appear first?

The official Discord server, usually alongside an update or a milestone such as a visit count or group member target. Milestone codes tend to expire quickly once the next milestone is reached.
