Field Depot is a Rare key in MW4 DMZ. It opens the gear maintenance room in the military supply warehouse at Chang-san Air Base, grid B5. Below is where the door is, how to get there and what we found inside.
- The door is in the big supply warehouse at Chang-san Air Base (B5), at the end of a side corridor off the warehouse hall.
- In through the open shutter, across the hall with the green crates and left into the corridor. No stairs.
- The air base was an Extreme threat area in our run.
- Seven containers with a Legendary Parachute worth $5,000 as our best find.
- Not really worth it. The area is busy and dangerous, and the rest of the air base has the same kind of loot without a key.
Where the Field Depot Door Is
The Field Depot is inside the big military supply warehouse at Chang-san Air Base, grid B5, northeast of the base clinic. The warehouse has a wide open shutter with a round emblem on the wall next to it. The door is not in the hall itself but at the end of a side corridor, a plain metal door with the Field Depot prompt. The key tooltip calls it the first floor. In our run it was the floor you walk in on. The air base was an Extreme threat area, with AI around the warehouse. You can also find the door under the keys layer on our interactive MW4 DMZ map.

How to Get the Field Depot Key
The Field Depot key is field loot, so it can drop from ordinary containers on Hajin. Ours came out of a duffel on a bunk in the North Korean Wilderness. We do not know of a fixed spawn for it. Every other key and the door it opens is in our MW4 DMZ keys guide.
The Route to the Door
- From the road east of the warehouse, cross the yard to the open shutter with the round emblem.
- Walk into the warehouse hall, past the green crates and the stairs.
- Turn left into the side corridor. The door at its end is the Field Depot.
What Is Inside the Field Depot
The gear maintenance room is one room with four military lockers along one wall, two MINA MS41 crates, which the game calls footlockers, and an armor box on the darker side by the desk. A Small Backpack and a Drill Charge lay loose in the room.

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
The military lockers had the best of it. One held a Legendary Parachute worth $5,000, a reusable parachute, next to a SAM Airburst Turret and a Hazard Storehouse key. Keys roll randomly, so do not count on that one. Another locker gave Degraded Execution Footage worth $2,000. The rest was lethals and tacticals, with a Claymore, two C4, Decoy, Snapshot and Smoke Grenades and two Drill Charges, plus six armor plates between the lockers, a footlocker and the armor box.

Is the Field Depot Key Worth It?
Not really. The Field Depot sits in a busy and dangerous part of Chang-san Air Base, and the same kind of loot is already all over the air base, where most areas need no key at all. Unless you happen to be standing at the warehouse, loot the rest of the base instead. If you carry the Weapons Mod Workshop key, its room in the repair garage on the same base is the better stop during Operation Iron Citadel.
