How to redeem codes in Junk Mechanics
You don’t need a separate settings menu for this one, the code box is tucked inside the shop. Here’s exactly where to look.

You’ll know it worked when a green “Code redeemed!” message pops up and your cash total in the top right corner jumps up right away. If nothing changes, double-check your spelling since these codes are case-sensitive.
How to get more Junk Mechanics codes
New codes for Junk Mechanics tend to show up around updates and milestones, so keeping an eye on the game itself is your best bet. You can jump into the Junk Mechanics Roblox page to check for announcements tied to new patches, since developers often tie fresh codes to those releases.
Bookmark this page and swing back by every so often, since codes expire without much warning and getting to them early means you actually get to spend the cash before they’re pulled.
Are Junk Mechanics codes free?
Yes, every code listed here is completely free to redeem. You just need to be playing Junk Mechanics on Roblox and past the tutorial for the redeem field to appear.
Why didn’t my code work?
The most common reason is a typo, since codes must be entered exactly as shown, including capitalization. If you’re still stuck, make sure you’re using a code from the working list above rather than one that’s already expired.
Grab the 20,000 cash from each of these codes while they’re still active and put it toward whatever upgrade you’ve had your eye on.
