How to redeem codes in Blue Lock Card Battles

You need two things before a code will actually apply, you have to be inside the game itself, and you need to already be a member of the official Blue Lock Card Battle Roblox group. Codes typed outside these conditions simply won’t register, so get that group membership sorted first if you haven’t already.

Settings menu open in Blue Lock Card Battles with the code entry field visible

Open Blue Lock Card Battles on Roblox and let your team lobby fully load in.

Tap the cog icon sitting in the bottom-right corner of your screen to bring up the Settings menu.

Type or paste a working code into the text box exactly as it’s written, capitalization and spacing included.

Hit OK to submit it. Your Cash balance should update on screen right away, that’s your confirmation the code went through. If a code has run out, the game will tell you it’s no longer valid instead of adding anything to your total.

How to get more Blue Lock Card Battles codes

New codes usually go out around card updates and season launches, so keep an eye on the game itself for those milestones. The developer’s official Discord server is where announcements typically land first, and it’s worth joining if you want to catch codes as soon as they’re posted. You can also jump straight into the Blue Lock Card Battles Roblox experience to redeem codes as soon as you spot them, just remember you need to be part of the official group first.

Are Blue Lock Card Battles codes free?

Yes, every code listed here is free to redeem and simply requires you to type it into the in-game Settings menu while playing.

Why didn’t my code work?

Double-check that you’re a member of the official Blue Lock Card Battle Roblox group and that you’ve typed the code exactly as shown, matching capitalization and spacing. If the code has expired, the game will tell you directly instead of adding any Cash.

Keep this page bookmarked and swing by whenever a new card update drops, that’s usually your best bet for catching fresh Cash before it runs out.
