CONTROL Resonant Medical Cabinet Code 0665 & Location

on

Updated September 25, 2026

A high-angle gameplay screenshot from the video game Control, showing the player character, Jesse Faden, from behind in a laboratory. A green storage unit with the number "0665" and the FBC logo is visible. A holographic interface overlay details the quest objective: "FBC FIELD HOSPITAL // UNIT 0665," "OBJECTIVE: Recover Anomalous Documentation," and lists the contents of "CABINET 0665 // CONTENTS." The environment is an SCP-style medical research room with equipment, chairs, and cables.

The CONTROL Resonant Medical Cabinet code is 0665. You'll find the locked cabinet inside the Field Hospital in Central during the Crossing the Threshold side story.

If the cabinet only gives you the "Ask for code" prompt, speak with Zoe and follow the new objective to the FBC Field Office Security Station. Use the relevant computer there to find the code, then return to the Field Hospital and open the cabinet.

Quick Answer

  • Medical Cabinet Code: 0665
  • Cabinet Location: Field Hospital, Central
  • Code Location: FBC Field Office Security Station
  • Quest: Crossing the Threshold
  • What to do: Talk to Zoe → follow Get the Archive Cabinet Code → visit the Security Station → find 0665 → return to the cabinet.

Medical Cabinet Code 0665

If you're looking for the number to enter into the locked cabinet, the answer is:

Medical Cabinet Code: 0665

However, the game doesn't simply hand you the number when you first examine the cabinet.

When you interact with the cabinet, you'll get an "Ask for code" prompt. Speak with Zoe and continue the investigation until the objective changes to Get the Archive Cabinet Code.

That objective sends you to the Security Station, where you can access the information needed to open the cabinet.

Where to Find the Medical Cabinet

A gameplay screenshot from Control showing the player character standing in front of a locked teal-green medical cabinet inside the Field Hospital. A highlighted overlay displays the Crossing the Threshold quest objective, while a magnified callout points to the cabinet keypad showing the code 0665, accompanied by an explanatory note about the active objective.

The Medical Cabinet is inside the Field Hospital in the Central area.

Reach the Field Hospital

Head into the Field Hospital and make your way toward the upper medical area.

The route includes a Clearance Level 01 entrance and a yellow-railed staircase. Once inside, continue through the medical offices and laboratory area.

Look for the teal-green medical cabinet in the secure section of the hospital.

Identify the Correct Cabinet

The cabinet is easy to identify once you're in the right room:

  • It is a teal-green medical cabinet.
  • It has a keypad on the front.
  • Interacting with it initially gives you the "Ask for code" option.

If you're standing in front of this cabinet and don't know what to do next, don't keep searching the room for another key.

Talk to Zoe first.

How to Get the Cabinet Code

After you examine the locked cabinet, speak with Zoe.

She explains that the security codes have been updated, but the local Field Hospital codes haven't been delivered yet.

The investigation then updates with the objective:

Get the Archive Cabinet Code

Zoe directs you to the Security Station.

This is the important progression step. You aren't expected to guess the cabinet combination or find a physical key inside the Field Hospital.

Follow the Security Station objective

Leave the Field Hospital and head toward the FBC Field Office Security Station.

The Security Station is located in a container-style structure and can be recognized by its exterior stairs and FBC markings.

You'll need Clearance Level 01 to enter.

FBC Security Station Location

A close-up gameplay screenshot from the video game Control, showing a retro-futuristic computer terminal. An overlaid infographic panel details the 'Crossing the Threshold' quest steps, with step 3 highlighted: '[!] Get the Archive Cabinet Code'. A magnified callout box points to the screen, clearly displaying the required security code '0665'. An arrow indicates the 'Interact' button on the keyboard. The scene includes background clutter like coffee mugs and a fan, with the game's objective list visible in the top-left.

Once you reach the Security Station, go inside and look for the computer terminals.

The building has an office-like interior with desks, filing cabinets and security equipment.

For the cabinet code, interact with the relevant computer and cycle through its screens until you find the cabinet information.

The code you need is:

0665

The Security Station also becomes important later in the Crossing the Threshold investigation when you need to examine CCTV footage, so don't assume you've reached the wrong place if you encounter additional security evidence.

How to Unlock the Medical Cabinet

Once you've obtained the code, return to the Field Hospital.

Go back to the same teal-green medical cabinet you examined earlier.

Interact with the keypad and enter:

0665

The cabinet will open, allowing you to examine the document inside.

You don't need to search for another combination after this. If the cabinet is still locked, make sure you've progressed the investigation far enough for the Get the Archive Cabinet Code objective to appear.

What's Inside the Medical Cabinet?

Opening the cabinet gives you the Dig Site Threshold Quarantine List.

The document contains information about members of the Threshold expedition and their condition or whereabouts.

Among the listed personnel are:

  • S. Lewis — deceased
  • R. Graham — deceased
  • A. Rutter — missing
  • T. Cox — missing/reassigned
  • C. Wilson — missing

The list connects the Field Hospital investigation to the wider Threshold Site 7-B incident.

It also helps explain why the investigation moves between the Field Hospital, Security Station, Loading Docks and the Threshold Dig Site.

You don't need to solve the entire side story before opening the cabinet. Once you've followed the code objective and entered 0665, the document is available for inspection.

Use the relevant computer and cycle through its screens to find the cabinet code.
