HUSH Roblox The Hollow Keycards: Locations and Route Uses

HUSH Roblox The Hollow keycards grant access to high-tier loot rooms, boss sectors, and locked facility extractions. Survivors can locate the Security Card, Lab Card, Staff Card, Black Card, and Red Card through specific furniture containers or boss encounters.

Hollow Keycard Selection and Route Planning

Each keycard in The Hollow opens a designated sector or extraction gate across the four underground facility levels. Survivors planning a raid must balance the time spent searching furniture against the danger of fighting bosses in close quarters.

Reviewing The Hollow map guide helps align these access points with active generator lines before committing to an escape route.

Security Card and Research Office Access

The Security Card is a blue card marked with a pale identification panel and labeled SEC CARD in your inventory. It occupies one inventory slot and unlocks the research office door beside the corridor with metal shelving, located below R22 and above R28 on the facility map.

To obtain the Security Card, navigate to room R13 (CCTV), situated northwest of the Central Atrium and directly above R14. This room functions as the Site Security monitoring post and sits adjacent to the Vent Raise Ladder extraction room. Inside R13, pass the computer desks, the central bookshelf, and the small drawer cabinet. Move toward the far wall to locate a long blue-gray locker standing beside a low red seat and a bookshelf. Searching this locker provides an opportunity to find the SEC CARD.

Swiping the card requires two distinct inputs at the target door. Approach the card reader until the prompt displays F to swipe the Security Card, then hold the key until the unlock bar completes. The door remains shut after unlocking until you trigger the separate open prompt.

Lab Card Spawns and MX Research Wing

The Lab Card, labeled LAB CARD and sometimes referred to as the Lab Access Card, is a green card that opens restricted laboratories and cold storage units inside the MX Research wing. Survivors who deploy without this card can pry open these doors with a Crowbar, though prying takes 6 seconds of sustained interaction and creates noise that draws nearby infected.

Searchable spawn points for the Lab Card appear in three distinct office locations:

1. Research Office Cabinet: Located between R22 and R28 behind the Security Card door. Walk past the front desk toward the wall displaying a painting and a wall-mounted safe. Search the low wooden cabinet directly beneath the painting.
2. Site Security Bed-End Desk: Located in the Site Security room containing long dining tables, colored chairs, and three floor beds along the wall. Search the wooden-topped desk sitting at one end of the three beds, identified by dark equipment and red and beige books stacked on top.
3. Office Desk Past Red Carpet: Exit the Site Security control room through the wooden door on the filing-cabinet side, follow the perimeter corridor, and step through the red diamond-carpet room. Open the wooden door beside the bookshelf to enter an office containing a green armchair and gray diamond carpet, then search the office desk.

Checking these containers during a quiet loot run fits strategies covered in the solo guide, allowing players to gather research gear without firing loud weapons.

Boss Keycards: Staff, Black, and Red Cards

High-value areas in The Hollow depend on keycards obtained directly from hostile encounters rather than static furniture.

The Staff Card grants entry to Security HQ through the connecting hallway north of MX Research. Flashlight-carrying security guards patrol the corridors leading toward the facility center. Defeating these guards offers a chance to loot a Staff Card from their remains, though the drop is not guaranteed on every kill.

The Black Card, marked with a red stripe and labeled BLACK CARD or Containment Card, drops from The Chief inside Security HQ. Defeating The Chief on Hard or Nightmare difficulty yields this card alongside police-grade firearms and attachments, which connects directly to the gold weapons locations tracked by facility runners. The Black Card unlocks the Director's Escape Tunnel extraction in the southwest sector, as well as the reinforced vault safe near Cell 05 in the Deep Mine.

The Red Card drops from The Mayor, a sprinting boss encounter located in the corridors near Cell 05. Collecting the Red Card allows players to open the locked director's door situated above map coordinate D21. The Red Card opens this executive office door, whereas the Director's Escape Tunnel requires the Black Card.

Keycard Durability and Extraction Mechanics

Keys and keycards in HUSH have limited durability and wear out over repeated use. Basic cards open two to three doors before breaking, while higher-tier security passes may expire after opening a single high-security doorway.

When using a keycard to clear a gate extraction, the player holding the card extracts the entire squad through the gate upon completion of the extraction timer. Keycards must remain inside your accessible backpack or rig storage during extraction; placing a required keycard inside your secure case prevents the game from validating the gate requirement.

Raids run on higher difficulties increase the danger around these doors. As detailed in the nightmare looting guide, boss encounters in Site Security and the Deep Mine feature faster infection timers, making rapid keycard execution necessary before calling an extract. New survivors preparing for their initial deployment can consult the beginner guide to understand inventory grid management before entering The Hollow.
