Call of Duty: Warzone’s has kicked off major changes to its map with Season 5, having fully blown the lid off of the stadium, revealing the secrets within. The big new secret is actually a puzzle within itself, and it’s going to take some time to solve. As you explore the newly revamped stadium, you will find various keycard doors in Call of Duty: Warzone.
These three hidden doors are all locked when you first find them, but they are something you will want to try and open. There’s a hidden fourth door at the top of the structure that allegedly contains some very nice loot and other bonuses. Players will be tripping over themselves to get these doors open, so it helps to know what to look for.
Each of the keycard doors in Call of Duty: Warzone hides their own unique little secrets, and it all acts as some kind of self-contained puzzle. For starters, you’re going to need the keycards for each door. Each keycard is a red card, with a certain code number attached. The drops for the keycards you need are random, so you may have to do some hunting. Keep in mind that if another player grabs the card before you, you can get it off of their body.
When you pop open a door with a keycard, there will be a computer inside with an image on its screen. Take note of that image as you will need it to open the final door.
All locked door locations in the stadium
There are a total of four doors and three keycards in the new stadium layout. The first three doors are color-coded to a specific keycard, so you will need to go around and find the right keycards for each door. There’s one on the middle level, lower level, and in the parking garage. You need a specific red keycard to open each of the doors.
- Middle floor: El-21
- Lower floor: Cl-16
- Parking Garage: P2-16
Use the map marked below to find where each door is located. The door of the south is the middle floor and requires the EL-21 card. The one close to the middle of the stadium is the lower floor and requires the CL-16 card. The northern door is in the parking garage, and requires the P2-16 access card.
Each of these three rooms is keyed to the final room, meaning you will need to unlock all three in one match to unlock the last one. You don’t need to do them in order it looks like though. There’s still some mystery as to what is beyond the final door though. The current speculation is that the final door is locked with some kind of code that has yet to be uncovered. So far, it appears that the code for the room is based on the images displayed on the computers you find, each of which contains a snippet of some kind of code. The codes displayed on the computer change every match.
As of now, there’s no concrete way to get the final door open yet. If that information becomes apparent, we will be sure to update the guide accordingly.
