Deep Vault 106 is a Legendary keycard in MW4 DMZ for X01, the Season 1 black site. Like the other gold three-digit Deep Vault keycards it does two things. It opens the X01 Deep Vault gate without being used up, and it unlocks Room 106, a medical lab on the lab level of the Deep Vault, grid D2 on the Data Center floor. Below is where the door is, how to get the card, the route and what we found inside.
- Room 106 is on the lab level of the X01 Deep Vault (D2), the first level you reach with the elevator behind the Deep Vault gate. Follow the corridor past the stairwell with the painted 1 to the door with the big 106 on the wall.
- The keycard opens the Deep Vault gate without being used up. Room 106 does use it up.
- It is field loot and keycards roll randomly. Ours came off a dead enemy operator in a Data Center stairwell.
- 6 containers with at least $19,850 in loot in our opening, including an LT Crate with a Legendary Jeogyeom shotgun ($4,300).
- Worth it. The loot is good, and the LT Crate makes it stand out, because the other Deep Vault room we opened, 301, has none.
Where the Room 106 Door Is
The Deep Vault is the long wing in the northwest of the X01 Data Center floor, from grid D3 up to C2 on the tac map, with the round Deep Vault gate at its southeast end. Room 106 is one level down, on the lab level you reach with the elevator behind the gate. The rooms there are numbered 101 to 106. On the tac map Room 106 sits in the middle of the wing, grid D2, which is also the grid on the keycard tooltip.
Coming from the stairwell with the big painted 1, follow the corridor to its end. The number 106 is painted large on the wall next to the door, and the card reader hangs on the wall by the door. The door is also on our interactive MW4 DMZ map under the X01 keys layer.

How to Get the Deep Vault 106 Keycard
Deep Vault 106 is field loot, and keycards roll randomly, so there is no fixed spot to farm it. Ours came off a dead enemy operator in a stairwell in the X01 Data Center. It was the only item in his backpack. The game labels it a key in the tooltip, worth $100.
The gold three-digit Deep Vault keycards all work the same way. Each one opens the Deep Vault gate and its own room further in, like Room 301 on the Deep Vault 301 keycard. The gate does not use the card up. Room 106 does. Our card was still in the secure slot on the lab level and was gone right after Room 106 unlocked.
To get into X01 you can pick it straight from the FOB deploy menu, as its own location with Free Roam, and you spawn inside the facility. Our X01 entrance guide covers the ways in, and every key on Hajin is in our MW4 DMZ keys guide.
The Route to the Door
- The Deep Vault gate. On the Data Center floor, follow the wide corridor northwest past the Deep Vault sign into the wing. The gate is a big round vault door at the back of a hall with crates, with a card reader on the wall next to it. A gold three-digit Deep Vault keycard opens it and stays in your inventory.
- The elevator down. Past the gate is a room with an elevator. Step in behind the square vault door in front of the car and ride it down to the lab level. Expect enemies in the corridors down there.
- Room 106 at the end of the corridor. Follow the corridor past the stairwell with the big painted 1 to its end. Room 106 is the door with the big 106 on the wall. Swipe the keycard at the card reader.

The Deep Vault goes on past the lab level. Room 301 is two levels further down, and the Core Room and Blix, the target the X01 orders send you to kill inside the Deep Vault, are further in. This page sticks to Room 106.
What Is Inside Room 106
Behind the door is a medical lab with an operating table under a big surgical lamp, heart posters on the wall, microscopes on the benches and cabinets along the walls. We opened 6 containers. There is an LT Crate, a supply crate, two weapons lockers, a footlocker and a rifle case, plus an Epic Medkit on the bench under the lamp.

Armor Plate Footlocker
From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
The LT Crate by the operating table held the best item, a Legendary Jeogyeom shotgun worth $4,300, together with an X-58 NYX, a 2-Plate Armor Vest, three Disposable Parachutes, High-Tenacity Fibers, Rigid Synthetics and a Screamer Mine. The first weapons locker gave an Epic WZ.55 Striga ($1,900), Regional Combat Notes, a 2-Plate Armor Vest, Reactive Metals and a Concussion Grenade. The second one had a Signal 50 ($1,900), three more Disposable Parachutes, Rigid Synthetics, Detonators, a Shock Stick and a Proximity Mine. The supply crate held Ballistic Flight Logs and Infantry Invasion Plans ($1,000 each), a Cronen Squall, a Shock Stick and a Throwing Knife. The rifle case had an Oris 8.6 and a Printed Circuit Board, and the footlocker only an armor plate. That adds up to at least $19,850 in the containers, with one Legendary and three Epic items.

Is the Deep Vault 106 Keycard Worth It?
Yes. The loot is good, and you need one of these gold three-digit Deep Vault keycards anyway, because they are what opens the Deep Vault gate.
The LT Crate is what makes Room 106 really interesting. The other Deep Vault room we opened, 301, has no LT Crate, and in our opening this one held a Legendary shotgun on top of two weapons lockers with an Epic and a $1,900 sniper rifle.
Our other X01 keycard pages cover Deep Vault 301, the Executive Room, the Audit Room, the Small Test Chamber, the Maintenance Room, Deep Vault 406, the Superintendent’s Office and Lt. Chol-Min’s Stash Room, each with its route and loot.
