Warzone 2: How to Get & Use Blue and Red Access Cards

Call of Duty: Warzone 2 Season 1 reloaded update recently went live with a bunch of new content and improvements. The newest update includes a new Building 21 area in the DMZ gameplay mode, filled with high-tier loot, cash, and AI bots guarding the zone. To access each and every room of Building 21, you will need to find Red and Blue access cards in Warzone 2.

But before you embark on the journey to find these Access Cards, it's worth noting that Building 21 is locked by default. As a result, you will need to find Building 21 key first in order to access this high-security area. Once you have it, follow this comprehensive guide to find and use Red and Blue access cards for Warzone 2 DMZ's Building 21.

While it's not officially confirmed yet, the Red and Blue Access Cards can be obtained from supply drops, planes, boss supply drops, and SAM Site drop. Apart from this, opening the Commander Helo and Airplane supply drops can potentially reward you with an access card.

Once again, it's worth noting that these methods don't guarantee that you will always find the Red and Blue Access cards. Since they will have random spawn locations, finding these access cards will be a daunting task for the Warzone 2 players.

Red and Blue Access Cards will be primarily used to unlock certain doors of the new Building 21 area in Warzone 2 DMZ mode. However, as of writing, Building 21 is currently unavailable in the game, which means these cards are useless until this new region goes live. Once the new map goes live, these cards will grant you access to the “security room near the Data Center.”

A Reddit user who goes by BrobiWanKinobe on the platform explained, "In Tarkov, if you have a Lab's Keycard, you were able to go to the Labs map when you deploy. Inside that map are locked rooms with the best loot in the game, and you need colored keycards to unlock the doors."

Since nothing's confirmed yet, we advise readers to take this information with a pinch of salt.

So that's it, everything you need to know about Blue & Red Access Cards in DMZ mode of Warzone 2.
