Ch 7 Secure Records Room location in Warzone 2 DMZ
You can find Ch 7 Secure Records Room in Al Mazrah City, a POI located in the north-western region of the map. The secure room is inside one of the buildings next to the huge TV Station Tower as indicated in the images above. Head inside the structure and unlock Ch 7 Secure Records Room door using its key.

The location isn't heavily guarded, however, you will find some unarmored AQ Soldiers in the area. As for the loot, we found an orange supply chest and some other items, including Gold Bars, on the shelves inside the room. Furthermore, if you ever come across a similar Ch 7 Editorial Department key, save it, as you'll need it for the final Tier 5 Black Mous Faction Mission called Flight Plans.
