How to Get Diamond Key Codes in Borderlands 3: BL3 Diamond Keys are a new thing you can get in the game. You can then use them in the Diamond Vault to get a bunch of cool stuff. As always happens when a new feature is added to a game, people want to know how it all works.

People want to know how to get Diamond Keys in BL3, where the Diamond Armory is, and what to do with them once they have them. In our Borderlands 3 Diamond Keys guide, we’ll talk about all of these things.

How to Get Diamond Key Codes in Borderlands 3

In Borderlands 3, you need the new Director’s Cut DLC before you can get Diamond Keys. This gives you access to the new way to advance, which is called “Vault Cards.”

In fact, it will give you the first one, Fallen Heroes, without you having to do anything. Once you put it on, you’ll see a new progress bar in the lower left corner, next to your regular XP bar.

When you level up your Vault Cards, you get things like legendary gear, cosmetics, and, most importantly for us, BL3 Diamond Keys. You can move the Vault Card bar forward by completing quests, killing enemies, exploring the galaxy, and just about anything else that gives you XP.

There are also new Daily and Weekly missions that give you and the Card huge XP boosts. The new tab in your ECHO makes it easy to keep track of these. Once you have a BL3 Diamond Key, you have to use it in the Diamond Vault, which brings us to our next point.

Where is Diamond Armory in Borderlands 3

The Diamond Armory is a new place in Borderlands 3 where you can use Diamond Keys. It is on Sanctuary III, right under the bridge of the ship. Just go to the ship’s control panel and jump over the railing to the level below.

If you turn away from the windows, the door will be right in front of you. When you walk through the door, you’ll see three walls and a chest that says “Choose Wisely.”

One has a symbol of a grenade, one has a symbol of a gun, and one has a shield. Then, how does everything work? So, let’s figure it out.
