Haejeok Radio Station is a Rare key in MW4 DMZ. It opens the radio broadcasting room at the northernmost relay station in Imjin Farmland, a dark room full of server racks with a handprint safe in the corner. Below is where the building is, the short walk to the door and everything we found in its 23 containers.
- The relay station is in Imjin Farmland, grid D6, the white building under the red radio mast.
- Take the concrete stairs on the east end and follow the hallway with the framed photos to the brown wooden door.
- Inside are 23 containers, most of them server blades, plus a handprint safe you open by holding the scanner.
- Ours held five intel items in the safe alone and a lot of electronics, at least $25,650 in loot.
- Fine for electronics, and the safe on top is pretty good for a blue key. No Epic loot like the higher tier keys, though.
Where the Haejeok Radio Station Is
The Haejeok Radio Station is the broadcasting room in the northernmost relay station in Imjin Farmland, grid D6. Look for the red radio mast. The relay station is the white concrete building at its foot, with a yellow ladder on the south wall and concrete stairs on the east end. The HUD calls the spot Imjin Suburb. The door is upstairs, a brown wooden door in a hallway lined with framed photos. You can also find it under the keys layer on our interactive MW4 DMZ map.

How to Get the Haejeok Radio Station Key
The Haejeok Radio Station key is field loot, so it can drop from ordinary containers on Hajin. 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
- Start at the south side of the white building under the red mast and walk east along the wall, past the yellow ladder.
- Take the concrete stairs up at the east end and go in through the door at the top.
- Cross the lobby with the wooden floor and turn into the hallway with the framed photos. The brown wooden door next to the framed photos is the one.
What Is Inside the Haejeok Radio Station
The door opens into one large, dark broadcasting room. Rows of server racks fill most of it, and each rack has a few server blades you can search. Desks with computers stand under the barred windows, and three MINA MS41 crates and a few bags sit on the floor. A green safe with a handprint scanner stands next to the racks.

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 safe is the best part of the room. Its scanner shows a red lock, but holding the interact button on it for a few seconds opens it. Ours held Nuclear Program Files, Degraded Execution Footage, an Encrypted Archive, Infantry Invasion Plans, two Ballistic Flight Logs and $100, worth $9,100 together. The game calls it a Cache, as it does a slot in one of the racks and a duffel by the window.

The twelve server blades are mostly electronics. Between them they gave Control Units, CPUs, a Printed Circuit Board, Electronic Sensors in half of the blades, an Epic Comms Module and a second Encrypted Archive, plus stacks of electronics, metals and synthetics. The gaming computers each had a CPU, and one of them an Epic Power Regulator. A military bag held a second Degraded Execution Footage. The footlockers had a second Epic Comms Module, a 2-Plate Armor Vest, an armor plate and Stims. There were no weapons in the room. Counting only items with a known value, the loot in the room was worth at least $25,650.
Is the Haejeok Radio Station Key Worth It?
Yes, it is fine for electronics. The server racks are the place to stock up on Control Units, CPUs and Electronic Sensors for crafting. On top of the electronics you also get a safe, which is pretty good for a blue key, and ours held five intel items. Beyond that it stays a blue key, so do not expect the Epic loot of the higher tier keys.
