How to open the Mercenary Vaults in Call of Duty: Warzone

Although the bunkers and their fast travel system are available to everyone, you can only unlock the Mercenary Vault with the Golden Keycard. This is a legendary loot item that you can pick up and store in your inventory until your death. Also, keep in mind that one Golden Keycard opens only a single Vault. Therefore, you need another one of these rare items to access a different Mercenary Vault.

Golden Keycards are legendary loot items and are difficult to find. Nonetheless, you can find them mainly from supply chests or by picking one up from a dead enemy's dropped loot.

• Huge cash piles.
• High-rarity weapons.
• Killstreaks such as Precision Airstrike and Cluster Strike.
• Field Upgrades such as Ammunition Box and Armor Box.
