Working Codes for Build A Blue Lock Squad
Free rerolls and refreshes — join The LockerRoom group before redeeming.
Welcome to the most up-to-date Build A Blue Lock Squad codes hub for September 2026. This Roblox gacha squad builder by The LockerRoom lets you collect over 200 Blue Lock characters, build your dream lineup, and climb leaderboards — and promo codes are one of the fastest ways to get free rerolls and refreshes without spending Robux.
Codes are released through official channels like the game’s Roblox group, Discord announcements, and milestone celebrations. Each code grants reroll tokens (used to replace low-tier players in your squad) and refresh tokens (used to reset your pull pool from the same roll). Understanding the difference between these two currencies is essential before you redeem anything — our Reroll Strategy guide explains when to use each one.

The milestone 10KMEMBERS code (100 rerolls and 100 refreshes) remains the largest single code reward ever offered. Multiple character update codes also remain active.

Requirements Before Redeeming
You must join The LockerRoom Roblox group before any code will work. This is a hard requirement enforced by the game, not optional. If a code fails, group membership is the first thing to check.
Once you are in the group, open the game and tap the Settings icon in the bottom-left corner of the screen. Enter your code in the text field and confirm.
What Rerolls and Refreshes Do
A reroll replaces the lowest-overall player in your current lineup with a new random pull from the gacha pool. This is your primary tool for upgrading squad OVR. A refresh resets the available characters in your current roll without consuming a full reroll — useful when your pool has several strong options and you want to see different combinations.
Maximizing Code Rewards
After redeeming, do not burn all your rerolls immediately. Review our High OVR Squad Guide to understand target OVR thresholds, then consult the Tier List to know which characters are worth keeping. Top picks like NEL Isagi, NEL Rin, NEL Nagi, Kaiser, Bachira, Barou, Shidou, Sae, Lavinho, and Kunigami should anchor any competitive squad.
How to Find New Codes Quickly
