Keep the Door Locked All Known Anomalies

What this list confirms

This is a recognition guide for the confirmed threats in Keep the Door Locked: the window anomaly, toilet anomaly, room hider, door breaker, and shadow figure. It does not claim a universal counter for every encounter. The game’s hotel-room survival loop depends on watching cameras, following rules, and deciding what to do with the door, so an accurate observation is more valuable than a confident guess.

Use this page at the start of a run to learn the names, then move to the individual guides when you need a focused reminder. Keep the anomaly checklist open if you are trying to determine whether something has progressed. A short note such as “window changed after camera check” is much more useful later than “something looked wrong.”

Window anomaly: compare stages

The window anomaly is confirmed to have stages. That makes it a priority for repeat observation: do not only look once, decide it is normal, and forget it. Check the camera, note the state, and compare the next view with what you previously saw. A staged threat rewards careful comparison because the key information is the change itself. Avoid inventing a fixed number of stages or an automatic outcome; the confirmed fact is that stages exist.

Toilet anomaly: inspect ordinary fixtures

The toilet anomaly demonstrates why routine room checks matter. A familiar object can become relevant, so scan the same places in a consistent order rather than staring only at the doorway. If you think you noticed it, verify through the available camera view or another safe observation opportunity. The goal is not to interact impulsively; it is to establish whether the room has broken its expected pattern.

Room hider: treat the room as occupied

A room hider shifts the threat model from a changed object to a possible presence in the room. Slow down, review the visible parts of the environment, and do not let a visitor at the door erase what the room itself is telling you. In a game built around split attention, this is exactly the kind of encounter that punishes a player who checks only one source of information.

Door breaker: a lock is not the whole plan

The door breaker is a confirmed threat and a reminder that the title’s instruction is not a complete strategy by itself. A locked door may be necessary, but you still need to watch for signs that the door or its visitor is the immediate problem. Compare its urgency against other threats with the threat ranking, then log the event so you do not confuse a sound, a visitor, and a door-focused anomaly on later runs.

Shadow figure: identify before reacting

The shadow figure belongs in the visual-recognition part of your routine. Lighting, movement, and camera angles can make players second-guess what they saw. Recheck when safe, distinguish a figure from an ordinary room shape, and do not claim a trigger that the official information does not establish. The practical win is earlier identification, not a made-up combat solution.

Use the list with progression tools

Anomalies matter because mistakes can threaten survival, sanity, and progress toward the Blood Money goal. They also sit beside door choices involving visitors and endings. After learning the five threats, read the visitors guide so a door event does not erase your awareness of the room. Use the ending tracker for the 10 days, golden skeleton, and grandma-key endings, and use the badge tracker to record official badge progress without treating a badge name as a walkthrough.
