How keys work in MW4 DMZ

Keys in Call of Duty: Modern Warfare 4 DMZ are loot items that unlock a specific locked room somewhere on Hajin. Each key's in-game description names the room and gives a Tac-Map grid square (letters west to east, numbers north to south), but not the exact door, which is why a DMZ key locations list saves a lot of searching. Opening a key room is worth XP, and the rooms often hold weapon cases, recipes, valuables and rare components.

Where to find DMZ keys on Hajin

Keys turn up in normal loot containers, as Story Mission and Operation rewards, and from bosses: Activision's Hajin guide says Lieutenants can drop the key to their own personal loot room. Keys are kept if you exfil with them, so a good habit is to check this list, plan the room on your next deployment and pick an exfil close to it.

DMZ exfil guide

Hajin has 23 reported exfil sites. Only some are active each deployment and they are marked with green smoke; call the helicopter, then hold the landing zone because exfils are ambush hotspots. See all DMZ exfil locations on Hajin, or use the nearest-exfil button on every key in the interactive map.
