Blue Lock Card Battles Codes (September 2026)

Blue Lock Card Battles is a Roblox card game built around the Blue Lock anime, where you collect player cards and battle other users. The developers hand out codes every so often that drop Cash straight into your account, which you can then spend on packs and card upgrades.

Working Blue Lock Card Battles Codes

Here’s everything you can redeem right now, along with what each one pays out.

Both codes hand over 5M Cash apiece, so redeeming them together nets you 10M Cash before you even open a single pack.

How to Redeem Codes in Blue Lock Card Battles

You redeem codes from inside the match lobby settings, not from a separate codes menu. Joining the game’s Roblox group before you type anything in is worth doing too, since a few rewards check for group membership and will get rejected if you skip that step.

Expired Blue Lock Card Battles Codes

These no longer work, so don’t waste time typing them in.

How to Get More Blue Lock Card Battles Codes

New codes tend to show up whenever the developers push a card update or wrap up an in-game event, judging by how many past codes are tied to update numbers and event names. Your best bet for catching these early is the game’s official Discord server, where announcements go out as soon as a code drops. Bookmark this page too and check back after any major update, since that’s usually when a fresh code lands.

Why didn’t my code work?

Double-check your spelling and capitalization first, since the redemption box is case-sensitive and won’t accept a code that’s off by even one letter. If the spelling checks out, the code has likely expired, in which case the game will tell you outright with a “code is expired” message.

Redeeming codes only takes a minute, so it’s worth running through the working list above before you queue up for your next match.
