If you're looking for the Warzone Stadium keycards and full access to all the rooms then you'll need the EL21, P216, and CL19 keycards. There's a CR-56 AMAX blueprint if you can pull this off so it's worth taking a team in (which you'll need) to collect all the cards and open up that final door to gets at all the loot.
Finding all three blue keycard locations is required to work out the final Warzone Stadium code so you really want to make this pretty much the entire point of dropping in, rather than chancing it if you happen to be passing during a Call of Duty Warzone match.
It's going to be busy though. Previously, this area was completely inaccessible and just had loot boxes littered around the exterior, but now Stadium is open, it's one of the most popular drops on the map. Here's everything you need to know about the Warzone Stadium keycards; EL21, P216, and CL19, which access the locked doors.
How to get the Warzone Stadium keycards
I opened doors in stadium with keycard, and inside was loot and computer showing this. I think it’s code to double doors in other side of stadium. from r/CODWarzone
If you've been playing Warzone for a while and are familiar with the red access keycards found in the Warzone bunkers aspect of the game, then the P216, CL19, and EL21 blue keycards should be a breeze. For everyone else, once you pick one up, it will show up on the left-hand side of the bottom-right UI, next to your health and armor.
You can find these keycards as random in drops throughout Stadium although it's worth noting that the letters are code:
- EL = Executive level
- Cl = Concourse level
- P2 = Parking level 2
Each key will appear somewhere on the level it's for, so if you're going for all three and the final Stadium access code then you really need a team to split up and take it all on at once.
Warzone Stadium door locations
Above, you can see a map of all four keycard doors, marked by the respective keycards you need. The green question marks represent the final locked door which needs the code generated by three computers, one in each room locked by the other keys.
Remember, the key names refers to the level its respective door is on - EL/Executive level, Cl/Concourse level, P2/Parking level 2 - so use that, along with the map to make life easier.
Warzone EL21 keycard - Executive level
First up is where you use the EL21 keycard. This door is on the top floor, hence the Executive Level bit. It's in the south-east section, once you reach the top floor, just follow the corridor until you find it.
Warzone CL19 keycard - Concourse level
You want to head down to the middle floor that easily connects to the bleachers for this door. The concourse level tends to be busy so prepare for a fight.
Warzone P216 keycard - Parking level 2
Finally, there's the P216 door on Parking Level 2 which is in the north-west corner of the parking section. You want to head down to the lowest level possible, which means going down another slope inside the garage.
Warzone Stadium access code
To open the final locked Stadium door you'll need the code displayed on all three computers in the other three rooms. This will consists of eight numbers and symbols that, when combined will let you work out a full eight digit access code.
This isn't a complicated code - each number is identical. Only the position of the symbols changes, so by lining them all up you'll be able to work out what number the symbol represents. Here's a simple example where we're going to use x, y and z for the symbols:
By lining up each number you'll see what symbol replaces it in the other codes, enabling you to swap in the correct digit. So in this example y = 2, x = 3 and z = 4, giving you a final code of 12344321.
And that's all there is to it. Kind all the cards to the three doors you can unlock, get the codes off the computers and workout what numbers the symbols represent to crack the Warzone stadium access code. While you'll get plenty of loot in the process, the real win is the CR-56 AMAX blueprint you'll unlock in the final room.
