Borderlands 3 Diamond Keys Explained: How to Get and Use

In Borderlands 3, players can unlock powerful gear through Diamond Keys—a special currency tied to the Vault Card system. If you’re not sure how to earn Diamond Keys or how to use them, this guide will break down everything you need to know, from obtaining the keys to using them for top-tier loot.

How to Get Diamond Keys in Borderlands 3

Diamond Keys are earned through the Vault Card system, which was introduced in a content update. This system includes daily and weekly challenges that, when completed, grant you Vault Card XP. As you level up your Vault Card by earning XP, you’ll unlock special chests containing various rewards. Among these rewards, you may find the rare Diamond Key.

Since acquiring a Diamond Key relies on RNG (random number generation), there’s no guarantee you’ll get one every time. However, the more Vault Card chests you open, the higher your chances of obtaining a key.

Tips for Earning Vault Card XP Faster:

• Complete Daily Challenges: Daily challenges are quick to complete and reset often, providing a steady stream of XP.
• Tackle Weekly Challenges: Weekly challenges offer larger XP rewards, so prioritizing them will speed up your progress.
• Team Up with Friends: Some challenges are easier to complete in co-op, so grab some friends to help you knock them out faster.

Getting Diamond Keys from Shift Codes

In addition to earning Diamond Keys through the Vault Card system, Shift Codes occasionally offer Diamond Keys as rewards. Shift Codes are special codes released by Gearbox Software during events, celebrations, or on social media platforms like Twitter. To redeem a Shift Code for a Diamond Key, simply enter the code in the Social menu under the Shift tab in-game. Keep an eye on Gearbox’s announcements or Borderlands community pages for new codes, as they can grant you rare rewards, including Golden Keys and sometimes Diamond Keys.

What to Do with Diamond Keys in Borderlands 3

Once you’ve earned a Diamond Key, head to Sanctuary III to put it to use. The Diamond Chest is located beneath the Bridge. Here’s how to open it:

1. Head to the room under the bridge and find the podium.
2. Spend 1 Diamond Key to unlock three cases filled with Shields, Weapons, and Grenade Mods.
3. You’ll have 5 minutes to choose one item from each of the three cases. Take your time and pick the best gear for your build!
4. After making your selections, a Legendary item will appear on the podium as a bonus reward.

This system ensures you not only get top-tier items from the cases but also guarantees a powerful Legendary item to add to your collection.

Understanding RNG and Maximizing Your Chances

Because Diamond Keys are subject to RNG, luck plays a role in when you’ll receive them. Although there’s no way to directly increase your chances of getting a Diamond Key, regularly completing Vault Card challenges and leveling up your Vault Card as often as possible is the best way to improve your odds.

If you manage to earn multiple Diamond Keys, you can repeat the process to score even more high-quality loot.

That’s all you need to know about Diamond Keys in Borderlands 3! This exciting reward system allows you to acquire rare and powerful gear, including Legendary items. Whether you’re looking to enhance your collection with new shields, weapons, or mods, Diamond Keys are your ticket to some of the best loot in the game.
