HUSH Hollow Keycards: Security, Lab, Staff, Black and Red
Last updated:
The Hollow's keycards lead to different rooms and routes. Start by matching the card's name to your destination, then use the furniture landmarks below to find the Security and Lab Card search spots.

Look for the blue SEC CARD in the far wall Locker in Site Security near R13 and Vent Raise Ladder. It unlocks the research office: hold F to swipe, then press F again to open the door. Search the office Cabinet beside the wall Safe or the Desk beside three floor beds in Site Security for a green LAB CARD. Staff Card opens Security HQ, Black Card is required for Director's Escape Tunnel, and Red Card opens the director's door above D21.
Which Card Opens Which Route?
| Card | Identification or source | Destination or search target |
|---|---|---|
| Security Card | Blue card with a pale identification panel; labeled SEC CARD | Unlocks the research office door beside the corridor with metal shelving. |
| Lab Card | Green card with pale identification panels; labeled LAB CARD | Look in the office Cabinet beside the wall Safe or the bed-end Desk in Site Security. |
| Staff Card | Can drop from flashlight-carrying security guards | Opens Security HQ. |
| Black Card | Black card with a red stripe | Required for Director's Escape Tunnel. |
| Red Card | Dropped by the Mayor | Opens the director's door above D21. |
Security Card and Lab Card each occupy one inventory slot. Their furniture search spots are loot opportunities, not guaranteed spawns.
For purchasable keys and their trader requirements, see Scrapper's keys and keycards.
Search the Wall Locker for a Security Card
Head toward R13, then find the Site Security room next to the Vent Raise Ladder extraction room. Use the neighboring extraction room as a landmark; the search target is in Site Security.
- Enter the room with computer desks and a central bookshelf.
- Cross to the far end of the room.
- Find the long blue-gray Locker against the wall, beside a low red seat and a bookshelf. Pass the small central drawer cabinet; it is not this search point.
- Approach the wall Locker and press F — SEARCH.
- If SEC CARD appears in its contents, transfer it into your carried storage.
Use the Hollow map guide to locate the R13 area and connecting passages. For help moving items out of a searched container, see the looting controls.
Swipe the Security Card, Then Open the Door
Carry a Security Card to the research office door beside the corridor with metal shelving.
- Approach the door's reader until the prompt shows F — SWIPE CARD / Security Card.
- Hold F until the UNLOCK action finishes.
- After the unlock succeeds, press F — OPEN to open the door and enter.
Unlocking and opening are separate actions. If the notification says Unlocked: Security Card but the door remains closed, use the OPEN prompt.
Check the Cabinet and Bed-End Desk for a Lab Card
Look for the green LAB CARD at either of these two distinct search points.
Research office: the low Cabinet beside the Safe
The office search area is below R22 and above R28 on the map. Enter through the Security Card door using the swipe-and-open steps above.
- Cross the office to the wall with a painting and a wall-mounted Safe.
- Select the low wooden Cabinet beneath the painting, beside the Safe.
- Press F — SEARCH, then transfer LAB CARD into your carried storage if it appears.
The target is the Cabinet, not the wall Safe or the Desk near the office entrance.
Site Security: the Desk beside three floor beds
Find the Site Security room with long dining tables, colored chairs, and three floor beds along the wall. This is a different furniture layout from the Security Card's computer-desk room.
- Walk to the wooden-topped Desk at one end of the three beds.
- Identify it by the red and beige books and dark equipment on top. The white computer desk is at the other end.
- Press F — SEARCH on the Desk and take LAB CARD if present.
If one Lab Card search point is empty, the other gives you another place to check.
Staff, Black and Red Card Routes
Staff Card: access to Security HQ
Look for guards carrying flashlights and wearing security-style clothing. They can drop Staff Card, but a card is not guaranteed from each guard. Search defeated guards and collect the card if present.
Use the passage connecting MX Research to the north side of Security HQ to approach the HQ. Bring Staff Card for its entrance.
Black Card: Chief loot and the tunnel exit
Search The Chief's remains in Security HQ for Black Card. It can appear in the Chief's loot in a Nightmare, nighttime raid. Identify it by the BLACK CARD label and its black face with a red stripe.
Black Card is required for Director's Escape Tunnel in the southwestern part of The Hollow. If that is your planned exit, retain the card for the route. See the Hollow extraction requirements to compare it with other exits.
Red Card: the director's door above D21
The Mayor drops Red Card, which opens the director's door above D21. This door and Director's Escape Tunnel are separate destinations: the door uses Red, while the tunnel requires Black.
For a run targeting the Chief and Mayor, use the Hollow boss preparation guide to plan ammunition, medical supplies, and carrying weight before pursuing their cards.
