Junk Mechanics Codes (November 2026)

Junk Mechanics is a car-flipping simulator on Roblox where you buy battered, damaged vehicles, repair and repaint them in your own garage, and then sell them on for a profit. Every successful flip grows your cash pile and lets you work on bigger, more valuable cars.

Cash is the fuel for everything in this game, and that is where codes come in. The developers at Oil Leak drop free codes around updates and milestones, handing out bonus Cash and Keys that speed up your next restoration. We have gathered every working Junk Mechanics code below so you can claim them before they expire.

How to Redeem Junk Mechanics Codes

Launch Junk Mechanics on Roblox.
Complete the tutorial first, as the code redemption field only appears once you have finished it.
Click the Shop button on the left side of the screen.
Scroll down to the bottom of the Shop menu.
Enter a working code into the code box and click Redeem to claim your reward.

You must complete the in-game tutorial before you can redeem any codes, because the code box does not appear until the tutorial is finished.

How to Get More Junk Mechanics Codes

The developers usually release new codes alongside updates, events and player milestones, so it pays to keep an eye on the game’s official channels. You can also join the official Junk Mechanics Discord server to chat with other players and get notified about new codes and updates. Following the Oil Leak Roblox group is another good way to catch announcements as soon as they are posted. We check for new Junk Mechanics codes regularly and update this page whenever a fresh one drops, so bookmark it and come back after every update.

Why Are My Junk Mechanics Codes Not Working?

If a code does not work, it is usually one of these three things:

Double-Check Typos: Codes are case-sensitive, so even one wrong letter will stop a code from working. Copy and paste each code exactly as it is listed above.
Join a New Server: Some codes only work on new or updated servers. Leave the game and rejoin a fresh server, then try the code again. Also make sure you have finished the tutorial, since codes cannot be redeemed at all until the code box unlocks.
Code Has Expired: Developers can switch a code off at any time without warning. If a code from the active list above stops working, it has most likely expired.
