Blue Lock Card Battles puts you in charge of building a soccer squad out of collectible cards, and Cash is the currency that decides how fast that squad grows. Since new players start with almost nothing in their wallet, redeeming codes is the quickest way to buy card packs, raise your income, and expand your roster without grinding matches for hours.
Working Blue Lock Card Battles codes
Three codes are currently active, and each one hands out a large Cash payout the moment you enter it.
FCUSTOMS— 10M Cash NEWCARDUPDATE23— 4M Cash NEWNEWELOSEASON3— Cash reward NEW
FCUSTOMS is the most valuable of the three, worth 10M Cash on its own, which is enough to jump straight into higher-tier card packs. Redeem all three while they last since none of them are guaranteed to stay active for long.
How to redeem codes in Blue Lock Card Battles
Before entering any code, join the Blue Lock Card Battle Roblox group and like the game, since some rewards are tied to group membership. Once that’s done, the redemption process only takes a few taps.
A successful redemption shows your Cash total increase immediately on screen. If the game instead displays a message saying the code has expired, double-check for stray spaces or typos before trying again.
What Cash is used for in Blue Lock Card Battles
Cash is the main currency across the entire game. It pays for card packs in the shop, expands your active roster beyond the starting five players, raises how much income you earn per second, and upgrades the ratings you get from 15-second claim rolls.
You can build up Cash over time by playing PvP and bot matches, but that path takes hundreds of games to reach the totals a single code can hand you instantly.
Expired Blue Lock Card Battles codes
These codes no longer work but are listed for reference in case they return during a future event.

Where to find new codes
New codes tend to appear alongside card updates, ELO season changes, and special events, so the fastest way to catch them is through the game’s own channels. The Blue Lock Card Battles Discord server posts announcements as soon as codes drop, and the Roblox group mentioned above is another reliable spot to watch.
Bookmarking a single page and checking back periodically saves time compared to hunting across multiple community channels every day.
With the new ELO season underway and card updates arriving regularly, keeping your Cash balance topped up through active codes makes it much easier to keep pace with tougher opponents and pricier packs.
