How to redeem codes in Junk Mechanics

You’ll only see the code box once you’ve made it past the opening tutorial, so get that out of the way first if you haven’t already.

Open Junk Mechanics on Roblox and finish the short tutorial if you’re a new player.

Click the Shop button on the left side of your screen.

Scroll down to the bottom of the Shop menu until you spot the code text box.

Copy a code from the list above and paste it into the box instead of typing it out, since codes are case-sensitive and one wrong letter will make it fail.

Hit Redeem. You’ll know it worked when a confirmation notice pops up and your Cash balance updates on screen.

New codes usually go out around updates or milestones, like the game hitting a visit count or a fresh patch dropping. Your best bet for catching them early is the official Junk Mechanics Discord server, where the developers post announcements directly. You can also check the Junk Mechanics page on Roblox for update notes that sometimes mention new codes.

Are Junk Mechanics codes free?

Yes. Every code the developers release is free to redeem and only asks for a few seconds of your time in the Shop menu.

Why didn’t my code work?

Codes are case-sensitive, so pasting instead of typing avoids most mistakes. If a code still fails after pasting it exactly, it’s likely expired.

Redeeming all five codes right now nets you 100,000 Cash, which is enough to skip several early upgrades and get straight to the parts you actually want.
