Redeem Golden Keys at Sanctuary III
Turn redeemed Golden Keys into a chest of gear at the ship’s designated location.
WHERE & HOW TO FARM
Redeem Golden Keys at Sanctuary III
Golden Key Loot Chest, middle Deck B on Sanctuary III, east of the Fast Travel station.
Before you go
- Redeem a Borderlands 3 SHiFT code on a SHiFT account.
- Reach Sanctuary III in the campaign.
- Have a Golden Key available in the game’s Mail tab.
Farming steps
- Open the Social menu and go to the Mail tab.
- Claim the available Golden Key from the in-game message.
- Travel to Sanctuary III and go to middle Deck B, east of the Fast Travel station.
- Open the Golden Key Loot Chest and review the offered gear.
- Keep upgrades that fit your build and sell or discard the rest.
- Repeat only if you have another key you are willing to spend.
- Keys are tied to their specific Borderlands title; a key for another game does not transfer to Borderlands 3.
- If you are saving keys for later gear, wait until your character has reached a level or build stage where chest results are useful.
Repeat, collect and use
Limited by the Golden Keys you redeem and claim. Each chest opening spends a key; there is no in-game loop here that replenishes them automatically.
Common mistakes
- Looking for the key in inventory without claiming mail: retrieve it through Social’s Mail tab.
- Opening the chest before you want to spend a key: each use consumes one.
- Expecting the chest to target a named legendary: compare general gear and use a dedicated farm for specific items.
When to stop or switch
Stop when the chest produces no useful upgrade or you want to save remaining keys for later progression.
