Here are all the ways ways to obtain a Golden Keycard in Warzone Season 4: 

• Rare drops from loot boxes scattered around Caldera
• Completing Contracts and obtaining them as rewards
• Looting them from the bodies of enemies that already found one

Unfortunately, there are no exact locations on the map that players can search to obtain a Golden Keycard. Get the keycards in the Call of Duty Warzone Caldera map and open the secret vault to get amazing loot.

Players can also expect some Easter Egg to be added in addition to the bunkers. Previously the bunkers on Verdansk led to Red doors that eventually became part of the lore in Warzone.
