Hello, Vault Hunters!
The reason why you might not be seeing the newly added Golden Keys is that once they’re redeemed on your account, they’re added straight into your Active Balance in the SHiFT Terminal in Concordia.
Head on over to Concordia and access the SHiFT Terminal! Once you’re there, tab over to “Repository” to see a list of all your redeemed Golden Keys. To access them, select as many as you want and they’ll be added straight into your inventory. You can then view them under the “Badass Rank” tab of your ECHO device.
