Step 2: Start Blue Lock Card Battles from its Roblox experience page at https://www.roblox.com/games/26250df17a1a054bb7912610c2a04d6a and wait until you load into the lobby.
Step 3: Open the Settings menu and look at the bottom of that menu for the Codes button.

Step 5: Press OK to confirm. If the redemption succeeds, the corresponding amount of cash is added straight to your in-game balance.
How to confirm a Blue Lock Card Battles code worked
After you press OK in the Codes menu, a working code immediately increases your cash total. Check the cash value shown in the lobby or pack shop and compare it with the amount you had before redeeming the code. If the number has not changed and no success message appears, the code was not applied.
Why a Blue Lock Card Battles code might not work
If a code fails to redeem, one of these reasons is usually responsible:
- The code is expired. All codes listed as Expired in the table can no longer be used.
- There is a typing error. Any mismatch in spelling, capitalization, or extra spaces causes the code to be rejected. Copy and paste to avoid mistakes.
- Group requirement not met. If you have not joined the required Roblox group for Blue Lock Card Battles, the game will not grant the rewards.
When a code continues to show as invalid even after checking these points, treat it as expired and move on to another working code.
