Junk Mechanics puts you in charge of a Roblox junkyard where you buy wrecked cars, repair and repaint them, then flip them for profit. Codes hand out free cash you can put straight into your next restoration job instead of grinding for it.

Codes go in through the in-game shop menu rather than a separate settings screen, and the process only takes a few seconds once you know where to look.

A green “Code redeemed!” notification confirms the code worked, and your cash balance in the top right corner updates immediately to reflect the reward.
Where to find new codes
The game’s description mentions that reaching certain like counts can trigger new code drops, but the game page itself doesn’t display any codes directly. The most reliable way to catch new ones is to check the Junk Mechanics Discord server, which you can reach through a link at the bottom of the game page. Any announcement about an update, patch, bug fix, or maintenance window has a chance of including a fresh code.
Note: If the Discord link isn’t visible on the game page, make sure your Roblox account has age verification enabled for external chat permissions, then refresh the page and look again.
Redeem both codes before starting your next repair job so the extra cash carries into whichever car you’re fixing up. Check back regularly, since Oil Leak, the developer behind Junk Mechanics, tends to release fresh codes alongside game updates.
