The Borderlands games have always hinged on their robust loot systems, and that's as true as ever for Borderlands 3. While there are many ways to earn great guns and items in-game, Gearbox also has the SHiFT program. Through this program, developers periodically release temporary codes which unlock in-game loot. Each code rewards players a varying number of golden keys. These are special consumables that are used to unlock the Golden Chest in Sanctuary III.

The Golden Chest contains some of the best possible loot in Borderlands 3, always rewarding guaranteed purple-tier weapons, class mods, grenade mods, and shields. Lucky players might even come across an E-tech weapon or purple-tier relics. Because it's a stable source of guaranteed awesome loot, it's important to keep an eye out for new SHiFT codes, which are released without notice and usually expire within a week or so.Borderlands 3 Class Mods

Every one of Borderlands 3's SHiFT codes gives a slightly different reward. Some will give multiple golden keys, while others only give one. The best way to stay up to date is to watch the Borderlands 3 Twitter account, where Gearbox CEO Randy Pitchford frequently tweets and retweets code releases.
