Use a known code for a campaign or Stranded lock. The combinations documented for Modern Warfare 4 are fixed, so you can travel straight to the named lock, enter the digits and take the reward. A key or keycard route is normally slower when it involves searching, looting, fighting, crossing the map and extracting. That is a practical conclusion from the different mechanics, not a measured stopwatch result: no published guide provides a controlled code-versus-key timing study.
The distinction matters because campaign and Stranded keypad locks are not the same system as a DMZ-style loot room. Campaign/Stranded codes can be entered immediately when you know them. DMZ rooms generally require finding a matching key, surviving the trip and reaching extraction with the loot.

Quick decision: code or keycard?
Choose the method that matches the lock:
- Campaign or Stranded keypad: use the documented combination. Codes are fixed for every player and platform, so clue hunting is optional when your only goal is opening the lock.
- DMZ-style loot room: obtain the required key, then plan a safe loot-and-exfil route. A campaign code does not substitute for a DMZ key.
- Chasing a collectible objective: read the clue note even if you already know the code. Opening the lock and registering a clue or collectible can be separate objectives.
The fastest route still depends on your position, enemies, movement and whether you already possess a key. The fixed-code advantage is that it removes the search step; it does not make travel to a distant lock instantaneous.

Gaming Route’s October 2026 guide counts 13 campaign code locks across four missions. It states that every combination is fixed—the same for every player on every platform. The table combines those campaign locks with the Stranded locations and the separate keypad-crate clues documented by The Based Otaku.

| Stranded (mission 10) | Base Camp container | 0024 | Keypad supply crate; leading zeroes are required. |
| Stranded (mission 10) | Cliff Near Base Camp | 0600 | Keypad supply crate; leading zeroes are required. |
| Stranded (mission 10) | Southeast Village | 0078 | Location listed in the consolidated Stranded code guide. |

Stranded therefore has eight documented code locations in the consolidated list: six keypad-puzzle supply crates and two hidden bunkers. The six-crate count comes from The Based Otaku’s guide; the consolidated location list also includes Southeast Village and South of Jamming Station alongside the four locations with published clue sequences.
How each code was derived or located
Following Orders: 214
Following Orders is mission 3 of the campaign. The clue for the lockbox/toolbox is in a kitchen cupboard. Enter 214 at the lock. The toolbox contains Medicine and a note, so this stop can provide both a practical item and an additional piece of mission information.
If you are completing the Noteworthy collectible objective, inspect the clue rather than simply entering the number from a guide. If you only need the toolbox contents, the known combination lets you skip the cupboard search.
Assassins: 5523, 7632 and 9103
Mission 8, Assassins, has three documented door combinations: 5523, 7632 and 9103. The published location list identifies them as the mission’s three door codes but does not assign a separate landmark name to each code. Use the door prompt and your current objective to determine which of the three locks you are standing at; do not assume that one code opens every door in the mission.

Stranded: eight locks, including six supply crates
Stranded is mission 10 and contains the largest group of keypad interactions. The codes are four digits, including zeroes at the front where shown. The six keypad-crate clues follow simple sequences:
- Base Camp: the clue sequence is 0006, 0012 and 0018; continuing the pattern gives 0024.
- Cliff Near Base Camp: the sequence is 9300, 6400 and 3500; the documented answer is 0600.
- Big Sign: the sequence is 1000, 1200 and 1230; the documented answer is 1234.
- Small Island: the sequence is 3456, 4567 and 5678; the documented answer is 6789.
The consolidated list additionally records 0078 at Southeast Village and 8609 south of Jamming Station. The two hidden-bunker combinations are 0330 at Farm Field Hidden Bunker and 0008 at Island Hidden Bunker. Enter every digit, including the leading zeroes.
Escape: 8410
Mission 13, Escape, has a wall safe coded 8410. Its contents include Gaz’s dog tags, and opening it contributes to the Never Forgotten unlock. If you are working toward that unlock, this is more than an optional loot stop.
Fastest campaign or Stranded route when you already know the code
- Identify the activity. Confirm that you are in the campaign or Stranded mission, not a DMZ-style session. The same-looking keypad prompt does not guarantee the same unlock rules.
- Match the landmark to the table. For Stranded, distinguish Base Camp, Cliff Near Base Camp, Southeast Village, Big Sign, Small Island, South of Jamming Station, Farm Field Hidden Bunker and Island Hidden Bunker.
- Travel directly to the lock. Avoid detours for a clue you do not need. Account for enemies and traversal hazards on the direct path.
- Enter the full combination. Type all four positions where the code has four digits. For 0024, 0078, 0330, 0600 and 0008, the zeroes are part of the combination, not formatting.
- Collect the reward and verify the objective. If the lock opens but a collectible challenge does not advance, return to the clue or note and interact with it; opening a container and recording a collectible can be separate actions.
This route is usually fastest because the only variable work is movement and combat. The code itself is not randomized, so restarting the mission or changing platforms should not generate a new combination according to the fixed-code documentation.

When a key or keycard route makes sense
Keys and keycards belong to the DMZ-style loot loop. They are loot items used to open rooms that contain better loot. Unlike a known campaign combination, acquiring one is a chain of activities:
- Find or earn the matching key. Your inventory must contain the key for the specific room; a code from a campaign guide will not replace it.
- Reach the room. Your route time changes with spawn position, map traversal, locked doors and enemy placement.
- Manage contact. Fighting, stealth, armor or a detour can add substantial time. A theoretically short route may be unsafe in practice.
- Unlock and loot. The reward value may justify the risk, but opening the room is not the end of the run.
- Extract. You must survive the trip to an extraction point. A failed extraction turns the time spent finding the key and room into a loss.
Because enemy contact, spawn location and extraction risk change from run to run, DMZ key routes have no single universal completion time. A key already in your stash can make the access portion quick; searching for that key during the same run is the part that usually makes the route slower and less predictable than entering a known campaign code.
Code entry versus keycard access: practical comparison
| Factor | Known campaign/Stranded code | DMZ key or keycard |
|---|---|---|
| What unlocks the target | Enter the fixed combination at the named keypad, safe or door. | Use the matching loot key or keycard on the designated room. |
| Search required | None if the location and code are already known; clue reading is optional unless an objective requires it. | Usually yes, unless the key is already in your inventory. |
| Travel variability | Primarily your route, movement and enemy encounters. | Spawn position, exploration, enemy contact, room location and extraction route all affect the run. |
| Code or item stability | Documented campaign combinations are fixed for every player and platform. | Key availability and routes can change with patches and live-game conditions. |
| Failure consequence | A wrong entry normally costs a retry or more time; the mission route remains available. | Death or a failed extraction can cost the key, loot and the time invested in the run. |
| Best use case | Campaign completion, Stranded cleanup and known safes, doors or crates. | Targeting a DMZ loot room when you have, or intend to obtain, its matching key. |
The comparison supports a clear default: a known code minimizes access overhead, while a keycard route is a broader loot-and-extraction operation. It does not establish a numerical time advantage because no controlled timing figures have been published.
Leading zeroes and other entry mistakes
Do not drop zeroes
A keypad reads 0024 as four positions, not as the shorter number 24. The same applies to 0008, 0078, 0330 and 0600. Enter the zeroes exactly as written. If the interface rejects a code, first check whether you omitted a leading zero or typed the digits in the wrong order.

Confirm the landmark before trying another code
Stranded has several geographically distinct locks. A valid code at the wrong keypad is still the wrong combination for your current target. Recheck whether the lock is at Base Camp, the cliff, Southeast Village, Big Sign, Small Island, south of Jamming Station or one of the two hidden bunkers.
Separate access from collectibles
The Following Orders cupboard clue illustrates the distinction. A guide can give you 214 and let you open the toolbox immediately, but a collectible or note objective may still require interacting with the clue. Do not treat a successful unlock as proof that every nearby objective is complete.
Do not transfer campaign codes to DMZ rooms
Campaign and Stranded combinations are fixed keypad data. DMZ-style rooms use keys or keycards as loot items. If a room requests an item rather than digits, searching for a code is the wrong recovery path.
A decision framework for a real run
Use the code immediately when all three conditions are true
- You are in a campaign mission or Stranded.
- You can identify the lock’s location from the documented list.
- Your goal is to open the lock or collect its contents, rather than discover the clue for an objective.
In this situation, travel directly, enter the fixed combination and leave once the reward or objective is secured.

Investigate the clue first when the objective demands it
If your checklist names a note, clue or collectible, take the short detour to interact with it. The number may be all you need for the door, but not all you need for completion tracking.
Plan a key route when the target is a DMZ loot room
Start with the key requirement, then choose a route that balances distance, enemy exposure and extraction. A route that reaches the room quickly but leaves no safe way out is not the fastest successful route. Treat the key’s availability and the map’s current conditions as variables rather than relying on a campaign code.
What “faster” can and cannot mean here
The fixed-code conclusion is operational: entering four known digits has fewer required activities than finding a key, reaching a room, fighting or avoiding enemies, looting and extracting. It is not a laboratory result. The available guides publish locations, combinations and mechanic descriptions, but no controlled completion times, route samples or stopwatch comparison.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For campaign and Stranded, your personal time will still vary with difficulty, checkpoint, movement skill, combat choices and how far you are from the lock. For DMZ, the spread is wider because the run begins with uncertain key availability and ends only after extraction. Use “code is faster” as the default planning rule, not as a promise of a specific number of seconds.
Patch and version awareness
Modern Warfare 4 early access opened on October 16, 2026. The code lists cited here reflect guides updated October 16–17, 2026. Fixed campaign combinations are intended to be stable, but live DMZ key availability and routes may change with patches. If a future update changes a room, prompt or key requirement, follow the current in-game objective and verify that the target is still a campaign/Stranded keypad rather than a DMZ loot room.
