- Killer Frequency Master of Unlocking achievement requires opening all six locked station doors.
- Key order follows story progression, with most keys supplied by Peggy.
- Two basement keys are found inside Clive’s secret room after specific story events.
- Best approach is to explore each newly opened area before advancing the next major call.
- Missable risk is low, but some keys only appear after the victim board changes location.
Killer Frequency Master of Unlocking Achievement Overview
The Killer Frequency Master of Unlocking achievement is earned by unlocking every door inside the KFAM radio station. It is a single-player progression achievement tied to exploration rather than a difficult dialogue choice. As the night develops, Peggy provides several keys, while the final basement keys require investigation after the station’s story events change.
The achievement has six required doors. You do not need to solve every caller scenario perfectly for the achievement itself, but following the main story is necessary because several rooms remain inaccessible until later scenes. The station gradually becomes a connected investigation space, so revisit lower floors whenever Forrest or Peggy moves important evidence upstairs.
Video Highlights:
- The station’s locked areas open in a fixed story-driven order.
- Clive’s secret room contains both of the important basement keys.
- The later office key is provided by Peggy near the end of the story.
- Exploring every unlocked room helps combine this achievement with collectible progress.
Open each door as soon as you receive its key. This creates a simple route and reduces the chance of overlooking the basement areas later.
| Achievement | Requirement | Difficulty | Play style |
|---|---|---|---|
| Master of Unlocking | Unlock all station doors | Low | Single-player |
| Doors required | 6 | Story-based | Exploration |
| Online connection | Not required | Offline-friendly | Narrative progression |
The Six Locked Doors and Key Order
The keys appear in a set sequence. Four are handed over during normal station progression, while two are hidden in Clive’s secret room. The order below matches the practical progression route and identifies the point at which each door becomes available.
| Order | Locked door | Key source | When to check |
|---|---|---|---|
| 1 | Reception/Stairwell | Peggy | Early station progression |
| 2 | Employee Area | Peggy | After the next station expansion |
| 3 | Fire Door | Peggy | Before the exterior route opens |
| 4 | Basement Stairs | Clive’s secret room desk | After being locked out and finding the secret room |
| 5 | Basement Storage | Hole in Clive’s secret room wall | After Forrest moves the victim board upstairs |
| 6 | Reggie’s Office | Peggy | Late-story station progression |
The first three doors are difficult to miss because Peggy gives the corresponding keys during the narrative. The two basement keys require more attention. After the story locks Forrest out and directs him toward the hidden area connected to Clive, search the secret room carefully rather than immediately returning upstairs.
The Basement Stairs key is on Clive’s desk. The Basement Storage key is hidden in a hole in the wall, but it only becomes available after the victim board has been moved upstairs. If you visit the room too early, the second key may not yet be present.
Do not assume the first visit to Clive’s secret room completes the basement search. Return after the victim board is moved, then inspect the wall opening for the final basement key.
Peggy’s Keys
The Reception/Stairwell, Employee Area, Fire Door, and Reggie’s Office keys are received during story progression.
Clive’s Desk
The Basement Stairs key is found on the desk inside Clive’s secret room after the station lockout sequence.
Hidden Wall Key
The Basement Storage key appears in a wall hole after Forrest moves the victim board upstairs.
Step-by-Step Unlocking Route
Use the following route to unlock every door without unnecessary backtracking. The exact dialogue choices used to save or endanger callers do not determine this achievement, but story progression controls access to the relevant rooms.
Open the Reception and Stairwell Door
Continue through the opening station sequence until Peggy provides the first key. Use it on the Reception/Stairwell door immediately. This creates access between the station’s main areas and the stairwell.
Enter the Employee Area
Progress through the next caller events until Peggy gives the Employee Area key. Unlock the door and search the newly available desks and station materials before returning to the broadcast room.
Unlock the Fire Door
Continue until Peggy provides the Fire Door key. Open it when the story directs Forrest outside. This route becomes important during the later investigation involving the missing record and the station’s exterior paths.
Search Clive’s Secret Room
After the station lockout sequence, enter Clive’s hidden room and take the Basement Stairs key from the desk. Use it to open the basement stair access.
Return for the Basement Storage Key
Wait until Forrest moves the victim board upstairs. Go back into Clive’s secret room and inspect the hole in the wall. Collect the Basement Storage key, then use it on the remaining locked basement door.
Open Reggie’s Office
Near the late-story investigation, Peggy gives the final key for Reggie’s Office. Unlock the door and inspect the office. Once all six doors have been opened, the achievement should unlock.
The most important timing detail is Step 5. The wall key is not simply part of the first secret-room visit. If you cannot find it, advance the story until the victim board has been moved and then revisit the room.
| Story phase | Main objective | Door-related action |
|---|---|---|
| Early broadcast | Establish station access | Receive and use the first key |
| Station expansion | Investigate employee spaces | Unlock Employee Area |
| Exterior investigation | Reach the rear route | Unlock Fire Door |
| Clive investigation | Search hidden evidence room | Take Basement Stairs key |
| Evidence-board update | Revisit the secret room | Take Basement Storage key |
| Final investigation | Search the manager’s area | Unlock Reggie’s Office |
The fastest reliable method is to treat every new key as an immediate objective: receive it, open its door, and search the room before returning to the broadcast desk.
What to Do Inside Each Newly Opened Area
Opening the doors is enough for the achievement, but the rooms also support other progression goals. Killer Frequency uses station spaces as evidence hubs, so searching as you go can reduce repeated travel during the mystery.
The Reception and Employee Area contain station materials that can assist with caller situations and background investigation. The Fire Door leads to an exterior route that becomes important when Forrest retrieves the missing record. Clive’s secret room is the most significant location for this achievement because it contains the basement keys as well as evidence connected to the central mystery.
Reggie’s Office is the final required room. Once Peggy gives you its key, open it before committing to the final confrontation. This is a useful point to confirm that all earlier doors have been opened.
Reception
Check the entrance and stairwell connection after receiving Peggy’s first key.
Employee Area
Search desks and staff materials before continuing the broadcast.
Clive’s Secret Room
Inspect the desk, photographs, tapes, reports, and wall opening.
Reggie’s Office
Use the final key and search the office before the ending sequence.
| Location | Primary value | Search priority |
|---|---|---|
| Reception/Stairwell | Connects station floors | High |
| Employee Area | Staff records and contextual clues | Medium |
| Fire Door route | Exterior access and later investigation | High |
| Clive’s secret room | Two keys and major evidence | Very high |
| Basement Storage | Additional investigation space | High |
| Reggie’s Office | Final locked station area | High |
The achievement tracks door access, not the number of clues collected. Still, searching unlocked rooms during the story is more efficient than trying to reconstruct the station layout at the finale.
Achievement Checklist and Troubleshooting
Use this checklist to verify progress before the final scenes. If the achievement does not unlock after opening the sixth door, walk through the station again and confirm that each listed door has visibly opened. The achievement is tied to all six locked doors, not simply collecting six keys.
Master of Unlocking Progress:
- Open the Reception/Stairwell door with Peggy’s first key
- Open the Employee Area door
- Open the Fire Door
- Take the Basement Stairs key from Clive’s desk
- Return after the victim board moves and take the Basement Storage key
- Use Peggy’s final key to open Reggie’s Office
| Problem | Likely reason | Recommended fix |
|---|---|---|
| Basement Stairs key missing | Clive’s secret-room sequence has not advanced | Continue the story until the lockout and secret-room search |
| Wall key missing | Victim board has not moved upstairs | Advance the investigation, then revisit Clive’s room |
| Final door still locked | Peggy has not reached the late-story key event | Continue the main broadcast sequence |
| Achievement not triggered | One door was opened but another was overlooked | Recheck all six locations in order |
| Unsure about progress | Keys and doors are easy to confuse | Compare each room against the six-door table |
This achievement can be combined with a broader completion run. The same exploration route helps with station collectibles, hidden evidence, and story-related achievements. If you are also pursuing the under-four-hour completion achievement, avoid unnecessary wandering, but do not skip the two required visits to Clive’s secret room.
For additional community reference, see the Master of Unlocking achievement guide on TrueAchievements. The guide confirms the six-door requirement and lists the key sources in progression order.
Before the final confrontation, verify the Fire Door, both basement doors, and Reggie’s Office. These late locations are the most commonly overlooked parts of the route.
