Blue Lock Card Battles Codes (September 2026)

Blue Lock Card Battles is the Roblox card game built around the Blue Lock anime, where you collect player cards and battle other squads to climb the ranks. Codes are the developer’s way of handing out free Cash, which you can put toward packs and card upgrades without grinding matches.

Working Blue Lock Card Battles codes

Here’s every code that’s currently redeeming rewards. Type them exactly as shown below, since a stray space or wrong letter case will get your code rejected.

CARDUPDATE27 Free Cash reward New

CARDUPDATE26 5M Cash

LORENZOULT 5M Cash

Tip: Join the Blue Lock Card Battle Roblox group before you redeem, since some rewards are tied to group membership and codes can get rejected if you skip this step.

How to redeem codes in Blue Lock Card Battles

You don’t need to hunt for a separate codes menu here. Everything happens inside settings once you’re in a match lobby.

Launch Blue Lock Card Battles on Roblox and give the lobby a moment to finish loading.

Tap the cog icon sitting in the bottom right corner of your screen to pull up the settings menu.

Paste one of the working codes into the text box exactly as it’s written above. Since codes are case-sensitive, typing them out from memory raises your odds of a typo and a failed redemption.

Press OK to lock it in. Your Cash balance updates right away if the code went through. If instead you see a message saying the code is expired, that code has already been retired.

Expired Blue Lock Card Battles codes

These codes stopped working and will return the “code is expired” message if you try them.

How to get more Blue Lock Card Battles codes

New codes tend to show up alongside card updates and in-game events, which explains why so many past codes carry names like CARDUPDATE followed by a number. The developer’s official Discord server is where announcements about fresh codes and upcoming events get posted first, so keeping an eye on it is your best bet for catching new ones as they drop.

Are these codes free?

Yes. Every code listed here is free to redeem and adds Cash directly to your account inside Blue Lock Card Battles, with no purchase required.

Why didn’t my code work?

If you get the “code is expired” message, that code has already been retired and won’t grant Cash anymore. Double-check your spelling and capitalization against the working list above before trying again.

Bookmark this page and check back after every card update, since that’s usually when the next batch of codes lands.
