There are fifty-six different keys to be picked up across Al Mazrah exclusively in the DMZ mode. These keys unlock doors littered all over the map, and they’re typically put in place to make it more challenging to secure the hottest, most high-value loot.
Unfortunately, it’s quite difficult to understand exactly where these keys go unless you have immaculate map knowledge. That’s a big ask, considering the game is barely two weeks old, but thankfully, one player has taken the time to produce a map highlighting the locations of every door, matching them with their respective key.

This makes life much easier for DMZ players, as they can now bring in keys that they’ve extracted from the map into their future raids, opting to head directly for the door that they now have the ability to unlock.
