The Koschei Complex bunker in Call of Duty: Warzone DMZ houses several hidden explorable areas and discoverable easter eggs. If you’ve come across a keycard called the L2 Restricted Zone Key, I’ve described in this guide what exactly is its purpose and where it can be used.
Where to use L2 Restricted Zone Key in DMZ
The L2 Restricted Zone Key unlocks thecyan-colored doorslike the one shown in the above image. These locked rooms can be found specifically in two sections of Koschei Complex:Alpha ClusterandFactory Admin. While the former can be accessed using a Car Battery and Jumper Cables, for the latter you’ll need a Factory Admin Room Key.

These areas are, well, L2 Restricted Zones inside which you can find some rarevaluablesrequired for missions. Most importantly, these rooms can be used to call in anexfilseparate from the two elevators that are marked on the map for every player. I suggest you keep one or two L2 Restricted Zone Keys in your key stash as you will need them for some Redacted faction missions.
After entering an L2 Restricted Zone you’ll have to take out someRiot Shield enemiesand possibly a sentry turret. There will also be somelaser trapsinside the room. You can either crawl under them or carefully disable them unless you’d like to be blown up by a C4 charge.
Where to find L2 Restricted Zone Key in DMZ
L2 Restricted Zone Keys are pretty easy to find if you’re looking in the right place. I’ve acquired these keycards multiple times from vintage desks and other loot caches in Koschei Complex. you may even purchase it from the shopkeeper in the Factory Admin section for $50,000 or trade it for 4 Wrench and 2 Scientist’s Notes. Furthermore, you’ll receive L2 Restricted Zone Keys as a completion reward forAbandoned OperatorandBrother In Armsmissions for the Tier 4 Redacted faction.
