## Key points

- DMZ keys open locked rooms and containers with valuable loot.
- The guide maps several keys to buildings across Hajin and The Grid.
- Some keys are earned through story missions.

## Summary

A guide explains where to use several keys in Modern Warfare 4’s DMZ extraction mode, where keys unlock doors and containers that can contain valuable loot. It matters because each key comes with only a brief location hint, and finding the right building or room can be difficult.

The guide covers keys including the blackmarket weapons locker, coin mining den, counting room vault, executive arms auction, Gangbyeong apartments A and B, gun store weapons lockers and Hanex guard station. Locations include shops and apartments across Hajin, a casino and fortified DBN Headquarters in The Grid, and a bank vault; some keys come from story missions. The guide is still a work in progress.
