DMZ X01 Staff Emergency Exfil Keycard: How to Use

The Staff Emergency Exfil Keycard opens X01's Emergency Egress Shafts, by the Cargo Bay and in the Medical Wing: unlock the shaft door with it, go down and you are out, with no lift to wait for. Print it at the X01 3D Printer from 2 CPUs, 4 Printed Circuit Boards and 8 Control Units, or loot one inside X01.

How to use the Staff Emergency Exfil Keycard

Six steps, each with what the game shows you at that point:

Switch Floor: Open the Tac-Map and find the Emergency Exfil Shaft icon closest to you, switching floors if it is not on yours.
Large Backpack: Walk up to the shaft door, open your backpack and select the keycard.
Emergency Exfil - Unlock: Press interact on this prompt ([F] on PC).
Exfil Activated: The door opens, and over the speakers the GRANIT Alarm System says: Egress ready.
Exfil Departing: Go down the shaft: at the Cargo Bay you slide down a duct.
Extraction Successful: You are out of X01, the same as at any other exfil.

You do not have to wait for the facility to shut down: the shaft opened while the Toxic Gas timer was still counting down. That makes the card worth carrying from the start of a run: once you have the Deep Vault loot or the Orders you came for, you can leave before the facility starts to shut down and before other squads gather at the lift. It pairs well with the free Argonaut Armor from the Deep Vault, since the Medical Wing shaft is the nearest way out of the vault.

Where the emergency exfil shafts are

The Cargo Bay shaft is at the area's top-left corner, square E2 on the Tac-Map, where the Emergency Exfil Shaft icon sits.
The Medical Wing shaft is inside the wing, square C4, on the floor that also holds the Deep Vault, the Tech Lab and the Bio Lab.

The X01 Tac-Map shows one floor at a time, and the two shafts are on different floors: press Switch Floor to see the other one. Both shafts, the exfil lifts and every area are marked floor by floor on our interactive X01 map, and the way down into X01 from Hajin is in our DMZ X01 guide.

How to get the keycard

Loot one inside X01, or print it at the X01 3D Printer, where it is an Epic recipe on the Keys page. The X01 3D Printer is in the Production Assembly, in the middle of the X01 Tac-Map: it stands in an upstairs office on the west side of the area, square E5, reached by a ladder and then stairs. Bring the ingredients in your backpack: it prints from what you carry.

The recipe asks for 2 CPUs, 4 Printed Circuit Boards and 8 Control Units, three tech ingredients you bring in from Hajin:

2 CPUs: search the Netshin Tech Complex server rooms, Cheonwang Peak Array server rooms and Deadtown hillside facade buildings. More on the CPU page.
4 Printed Circuit Boards: search the Haneul Nuclear Reactor and electrical substations. More on the Printed Circuit Board page.
8 Control Units: found in computers and tech bags, or print them yourself from 20 Electronics and 20 Metals. More on the Control Unit page.

Which container is best for CPUs and the other tech parts is in our container loot guide, and every other recipe, Season 1's included, is on our 3D Printer recipes page.

The keycard shaft against the other ways out of X01

Way out	You need	Where	When	Wait
Emergency Exfil Shaft	A Staff Emergency Exfil Keycard	By the Cargo Bay and in the Medical Wing	Any time, even before the gas timer runs out	None: it opens as you unlock it
Exfil lift	Nothing	The exfil points the facility has not closed yet; after the gas, only the Final Exfil, in one area per match (it has been the Admin Offices, the Tech Lab, the Medical Wing, the Motor Pool or the Logistics Tunnel)	Until the facility closes them; the Final Exfil comes up after the 20-minute Toxic Gas timer and has to be reached within the 5-minute shutdown	About 30 seconds for the lift, then a 25-second countdown
Power Generators gate	Wheelson's Remote Module and the power switched off	The bottom floor of the Power Generators	Once the console and the power supply are shut down	One player keeps turning the wheel while the rest run through

Calling a lift brings the guards nearby down on you, and the countdown runs the same however many of your squad are inside. Fulton Drop Markers do not work in X01, so whatever you want to keep leaves with you. The lift is the way out everybody knows about, so expect other squads there. The gate costs a Commander fight first: Wheelson holds the Logistics Tunnel, and how to take it down is on our DMZ bosses page. The keycard skips both. Ghost's first page of X01 Orders asks you to extract from X01, and any of the three ticks it off: see the DMZ Orders checklist.

Questions

What does the Staff Emergency Exfil Keycard do in DMZ?

It opens an Emergency Egress Shaft in X01, a way out of the facility of your own. Unlock the shaft door with the card, go down the shaft and you exfil there: no Final Exfil to wait for and no lift to call. The item card reads "Used to unlock Emergency Egress Shafts in X01".

How do you get the Staff Emergency Exfil Keycard?

Loot one inside X01, or print it at the X01 3D Printer, where it is an Epic recipe on the Keys page. Printing it takes 2 CPUs, 4 Printed Circuit Boards and 8 Control Units.

Where are the emergency exfil shafts in X01?

There are two, by the Cargo Bay and in the Medical Wing. The Cargo Bay shaft is at the area's top-left corner, square E2 on the Tac-Map, where the Emergency Exfil Shaft icon sits. The Medical Wing shaft is inside the wing, square C4, on the floor that also holds the Deep Vault, the Tech Lab and the Bio Lab. The X01 Tac-Map shows one floor at a time, and the two shafts are on different floors: press Switch Floor to see the other one.

How do you use the emergency exfil in X01?

With the card in your backpack, go to a shaft door, select the card and press Emergency Exfil - Unlock. Exfil Activated comes up and the door opens; go down the shaft and Exfil Departing shows, then Extraction Successful.

Can you use the emergency exfil shaft before the gas?

Yes. You do not have to wait for the facility to shut down: the shaft opened while the Toxic Gas timer was still counting down. So the shaft works as an early way out with your loot, not only as a last resort once the shutdown starts.

Do you need the keycard to get out of X01?

No. Without it you call an exfil lift and wait for it; once the Toxic Gas timer runs out, the only lift left is the Final Exfil. Wheelson's Remote Module also opens an emergency exfil gate in the Power Generators. The keycard is the way out with no lift to wait for.

Where is the 3D Printer in X01?

The X01 3D Printer is in the Production Assembly, in the middle of the X01 Tac-Map: it stands in an upstairs office on the west side of the area, square E5, reached by a ladder and then stairs. Bring the ingredients in your backpack: it prints from what you carry.

Do Fulton Drop Markers work in X01?

No. Fulton Drop Markers do not work in X01, so whatever you want to keep leaves with you. That is one more reason to carry the keycard: the shaft gets you and your loot out without a lift to wait for.

Is it the same as the Encodable Blank Keycard?

No. The Encodable Blank Keycard is the other X01 keycard you can print: a blank keycard you encode at a Keycard Encoder Station inside X01. It takes 6 Printed Circuit Boards and 8 Control Units and does not open the shafts. The two encoder stations are in the Supply Depot and by the Data Center.
