All MW4 DMZ keys and where to use them
The article maps keys in MW4’s DMZ mode to the locations where they unlock lockers, vaults and other areas. The keys’ descriptions point to broad map zones rather than exact spots, so the guide is intended to help players find the rewards and plan where to use each key.
It groups the locations by map area, including Political Prison, Cheongun Village and Mirae Hospital, Hanuel Nuclear Reactor, Songdo Wharf and The Grid, Wolves Stadium and Hajin River Heights, Imjin Farmland, and Air Base and Deadtown. Some keys work in more than one location; others are area-specific. The guide also flags hazards: the prison and casino are hostile, while the reactor’s radiation can damage players and wear down gas masks.
In short
- The guide matches DMZ keys to their map locations.
- Some keys work in multiple areas.
- Radiation and hostile zones make certain locations risky.
Explained simply
MW4’s DMZ mode is a game mode set on a large map, where players explore areas and collect equipment while facing dangers. Keys found during play can unlock lockers, vaults and other spaces containing rewards.
The locations include places such as a prison, hospital, nuclear reactor and air base. Some keys work in several areas, while others are tied to one place, and the descriptions often give only a general zone. Hazards vary by location: some areas have hostile enemies, and radiation can harm players and damage gas masks.
