Junk Mechanics puts you in charge of a car-flipping business, buying wrecked vehicles from the junkyard, fixing them up, and selling them for a profit. Codes hand out free Cash and Premium Auction Keys that let you buy more vehicles and bid at auctions without waiting on slow early-game earnings.

How to redeem Junk Mechanics codes
Code redemption only unlocks after you finish the opening tutorial, so newer players need to sell their first car before the code box becomes available.
Expired Junk Mechanics codes
No Junk Mechanics codes have expired as of now. Every code listed above still works, though codes in live-service Roblox games can be pulled without warning, so redeem them while they last.
Where new Junk Mechanics codes get announced
New codes tend to arrive after major updates or when the game reaches player milestones. The official Junk Mechanics Discord server is where the developers post them first.
Put any free Cash toward the priciest junkyard vehicle you can afford, and fix mechanical problems before worrying about paint jobs, since buyers pay more for a car that actually runs.
