Roblox Junk Mechanics codes (September 2026)
Get free Cash & more
New Junk Mechanics codes give you free Cash and Premium Auction Keys to spend on your car restoration business.
Cash is especially useful because almost everything in Junk Mechanics revolves around buying damaged cars, repairing and repainting them, and flipping them for a profit. A few free rewards can help you afford better project cars without grinding through as many early restorations.

How to use Junk Mechanics codes
You need to complete the opening tutorial before you can redeem codes.
Once that's done:
- Launch Junk Mechanics on Roblox.
- Complete the tutorial and initial car sale.
- Select the Shop button on the left side of the screen.
- Scroll to the bottom of the Shop.
- Find the Codes box.
- Enter a working code.
- Press Redeem to claim your reward.
Codes should be entered exactly as shown above. Copying and pasting them is the easiest way to avoid spelling mistakes.
Why is my Junk Mechanics code not working?
First, make sure you've completed the tutorial. The code redemption section isn't properly accessible until you've finished the game's opening sequence.
If you've already done that, check that the code is entered exactly as shown. You can also leave the game and join a fresh server, particularly when trying to redeem a newly released code after an update.
The code may also have expired or already been redeemed. Junk Mechanics regularly receives milestone and update codes, and older rewards can disappear as new ones arrive.
How to get more Junk Mechanics codes
New Junk Mechanics codes tend to appear alongside game updates and community milestones. The official Roblox community currently points toward like milestones for new code drops, while the Junk Mechanics Discord server is another useful place to follow update announcements and new rewards.

What is the Roblox Junk Mechanics game about?
Junk Mechanics is a car restoration and flipping game from Oil Leak.
You search the junkyard for damaged vehicles, buy promising cars, repair what's broken, repaint them, and then sell your restored vehicles for Cash. The money you earn can be reinvested into increasingly valuable cars as you expand your collection.
The official game description sums up the main idea simply: buy a car, repair it, sell it, and collect them all.
Cash from Junk Mechanics codes therefore goes directly back into progression. More starting money means you can afford additional project cars and work toward rarer vehicles without relying entirely on profits from your first few flips.
Redeem 30KTHANKS and DELAYMECHANICS2 first, then try the older codes above while they're still being reported as active.
