Redeeming A SHiFT Code In Borderlands 3
To enter SHiFT codes, access the Extras menu from the Main Menu and enter the code.
Players can unlock additional Golden Keys via codes given away by Gearbox or its employees. Codes can be entered only once per SHiFT account and are independent of your character saves you’ve got; meaning, one key works across all your saves. Codes given away online are not single-use, all users can use the same code, but there are time limits on when the code can be entered. After the time period is over, the code becomes unusable.
