MW4 DMZ Keypad Codes: Where to Find Each Mission Code
This guide lists where to find the keypad code for each story mission in Call of Duty: Warzone 2’s DMZ mode that requires one. You enter these codes on a numeric keypad to open a specific door or safe, and the location of the code is always tied to the mission’s objectives. Below, each mission with a keypad is covered, along with the exact spot to look for the code.
Background: Why Keypad Codes Exist in DMZ
Keypad codes were introduced in DMZ as part of the faction story missions, starting in Season 1 and continuing through later seasons. They add a small puzzle layer on top of the usual looting and combat. The codes are not random—each one is fixed for a given mission, but you still have to find it in the world before you can use it. This prevents players from simply memorizing a universal code and skipping the intended exploration. The keypads themselves are standard numeric entry devices attached to reinforced doors or weapon lockers, and they require a code that is usually written on a whiteboard, a sticky note, or a computer screen inside the same building or a nearby structure.
How the Code-Finding Mechanic Works
When you accept a story mission that involves a keypad, the mission objective will say something like “Find the code” or “Locate the keypad code.” The code is always in the same place for that mission, but it is not marked on your tac map. You have to physically go to the location and look at the object that holds the code. Once you read it, the mission updates and the keypad becomes interactive. If you already know the code from a previous run, you can skip the search and enter it directly—the game does not require you to re-find it each time. However, the code is only valid for that specific mission instance; you cannot use it on a different keypad elsewhere in the map.
Where to Find Each Story Mission Keypad Code
Below are the known story missions that require a keypad code, and the exact location of the code for each. These are based on the standard mission design and are consistent across matches.
- Mission: “Signal Intelligence” (Legion Faction) – The code is on a whiteboard inside the second floor of the police station in Sa’id City (Al Mazrah). The keypad itself is on the door to the evidence room on the same floor.
- Mission: “Denied Area” (Legion Faction) – The code is on a computer monitor in the back office of the airport terminal, near the baggage claim area. The keypad is on the door to the control tower.
- Mission: “Archives” (White Lotus Faction) – The code is on a sticky note attached to a filing cabinet in the basement of the Al Bagra Fortress. The keypad is on the door to the archive room.
- Mission: “Caved In” (Black Mous Faction) – The code is on a clipboard on a desk inside the cave complex near the eastern edge of the map, just past the first turret. The keypad is on the blast door deeper in the cave.
- Mission: “Break Check” (Crown Faction) – The code is on a whiteboard in the maintenance shed at the Hafid Port. The keypad is on the door to the shipping container office.
If you are playing a mission not listed here, check the mission brief—if it says “keypad” or “code,” the location is always within the same building or compound as the keypad itself. Look for any interactive object with a prompt to “Read” or “Inspect.”
Common Problems and How to Solve Them
Players often run into a few issues when hunting for keypad codes. The most common is that the code object does not show a prompt, even when you are standing right next to it. This usually means you are at the wrong object—the game only highlights the correct one with a subtle glint or a small icon. Another frequent issue is that the keypad does not accept the code even though you found it. This happens if you are at the wrong door or if you have not completed a prerequisite objective, such as killing a specific commander or looting a key. If the code is not working, double-check that you are at the exact door the mission points to, and that your mission tracker is active. Sometimes the code changes if you are in a squad and a teammate already used it—the door stays open for everyone, but the code may reset for the next player.
Tips for Finding Codes Faster
If you are in a hurry, here are a few practical tips that work across all missions:
- Always check the second floor or basement first—most codes are not on the ground floor.
- Look for whiteboards, computer screens, and sticky notes; these are the three most common code containers.
- If you have a recon drone or a spotter scope, use it to scan the room from outside before entering.
- In a squad, split up—one player searches the building while another covers the entrance.
- If you have already completed the mission once, the code stays the same in future runs, so write it down.
Alternatives to Finding the Code Manually
If you do not want to search for the code, there are two alternatives. First, you can use a mission-specific key that you loot from a supply drop or a HVT—this opens the door without a code, but the key is a rare drop and only works for that one door. Second, you can simply follow a squadmate who already knows the code; if they enter it, the door opens for everyone in the squad, and you do not need to find the code yourself. However, if you are playing solo, you must find the code or bring the key. There is no way to brute-force the keypad—you only get a few attempts before it locks temporarily, so do not guess randomly.
Frequently Asked Questions
Do keypad codes change every season?
No, the codes for story missions are fixed per mission and do not change between seasons. However, if the mission is reworked or the map changes, the code location might move, but that is rare.
Can I use a keypad code from a different mission?
No, each keypad is tied to a specific mission door. A code from one mission will not work on another keypad, even if it looks similar.
What happens if I enter the wrong code too many times?
The keypad will lock for about 30 seconds, and you will hear a buzzing sound. After the lock expires, you can try again, but you still need the correct code.
Is there a way to bypass the keypad without a code?
Yes, you can use a mission-specific key if you loot one, or you can have a teammate who knows the code open the door for you. There is no other bypass.
Do I need to find the code every time I replay the mission?
No, once you have found the code in a previous match, you can enter it directly on subsequent runs. The game remembers that you have discovered it.
Are the code locations the same on Vondel or Ashika Island?
The story missions that use keypads are primarily on Al Mazrah. On Vondel and Ashika, the missions are different and do not use keypad codes in the same way, though some side easter eggs may have codes.
