## Key points

- The guide matches DMZ keys to their map locations.
- Some keys work in multiple areas.
- Radiation and hostile zones make certain locations risky.

## Summary

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.
