Quick Guide
  • Keep the Door Locked when to open the door: Only open it when the game clearly confirms the visitor is safe.
  • Default rule: Treat every unexplained knock as dangerous and inspect the peephole first.
  • Window events: Check tapping quickly, but do not leave the room for a suspicious hallway visitor.
  • Power cuts: Reset the breaker promptly by turning left toward the hall panel.
  • Night survival: Keep the curtain closed and sleep with other players in the room.

Keep the Door Locked when to open the door

The central decision in Keep the Door Locked when to open the door is simple: opening the door should be the exception, not the standard response. The hotel uses knocks, strange voices, power failures, and other distractions to make you leave a safe room at the wrong time.

When somebody knocks, do not open the door immediately. Use the peephole, camera, or another viewing method first. If the visitor speaks unnaturally or gives you a reason to distrust them, keep the lock engaged and wait. The safest response is to remain inside until the event passes.

Video Highlights:

  • The door remains shut when an unknown person knocks.
  • A peephole or camera helps identify suspicious visitors.
  • The curtain should stay closed during the night.
  • The breaker must be reset quickly after a power failure.
  • Sleeping with other players helps prevent the bathroom threat.
Door Rule

If you cannot positively identify the visitor, do not open the door. A familiar voice alone is not enough evidence.

When should you open the hotel door?

The available guidance does not support opening the door for random knocks or strange dialogue. Instead, wait for an explicit progression cue. After surviving a later day, the front desk indicates that a key is available for leaving the hotel. This key is the clearest confirmed exit path.

The important distinction is between an instruction to inspect and an instruction to open. The game encourages you to look first, but looking through a peephole does not mean the door should be unlocked. Use observation to gather information while preserving the room’s protection.

Why the lock matters

The locked door gives you time. It prevents a suspicious visitor from entering while you assess the situation. Leaving the room can expose you to a knife-wielding threat in the hotel, especially during a breaker event when your attention is already divided.

Keep your movements deliberate:

  • Inspect before interacting.
  • Do not follow a strange voice into the hallway.
  • Return to the room after completing a required maintenance task.
  • Avoid unnecessary door openings during dark or uncertain events.

Night Survival Rules and Threat Responses

The hotel’s survival pattern combines several rules that must be followed together. Locking the door is important, but it is only one part of the nightly routine. You also need to manage the curtain, breaker, sleep conditions, and hallway threats.

Do Not Chase the Threat

A knife-wielding figure may be present in the hotel. Complete only the required objective, then return to your room instead of exploring.

Locked Door

  • Check first
  • Reject strange visitors
  • Preserve your safe position

Closed Curtain

  • Keep the window covered
  • Avoid unnecessary inspection
  • Treat tapping as a timed event

Shared Sleep

  • Do not sleep alone
  • Wait for other players
  • Use a full room when possible

Threat response table

Threat or eventWhat to doWhat to avoid
Strange knockWatch through the peephole or cameraUnlocking immediately
Window tappingCheck it quickly when requiredIgnoring the event for too long
Power outageLeave for the breaker panel and reset it fastWandering through the hotel
Bathroom dangerWait for others before sleepingGoing to sleep alone
Hallway attackerKeep distance and complete only necessary tasksSearching for the attacker

Window tapping versus door knocking

These events require different reactions. A knock at the door calls for caution and observation. Window tapping is treated as a quick-check event, so delaying too long can create additional danger. The safest routine is to keep the curtain closed normally, then investigate the window only when the tapping begins.

Do not confuse urgency with permission to explore. A quick check means you should perform the required interaction efficiently and return to the room. It does not mean you should open the door, search the hallway, or inspect unrelated areas.

Sleeping safely

The bathroom contains a threat that does not attack a full room. Before sleeping, make sure other players are present. If you are alone, wait rather than treating sleep as a harmless transition.

This rule is especially important after completing a stressful objective. Players often rush to sleep after restoring power or surviving a visitor event. Pause at the room entrance, confirm the group is together, and only then continue.

Breaker Reset Walkthrough

The breaker event is one of the clearest moments when you must leave the room. The instructions direct you into the hall, but the task should be handled as a short maintenance trip rather than an invitation to explore.

Fast Route

When the lights trip, leave the room, turn left, locate the breaker box, reset the power, and return without detouring.

1

Confirm the Power Cut

Wait for the lights to trip and the breaker objective to appear. Do not leave early because the hallway may contain a hostile figure.

2

Exit and Turn Left

Open the room door only for the required objective. Once outside, turn left as directed instead of searching other rooms or corridors.

3

Find the Breaker Box

Locate the hall panel and interact with the breaker box. Keep your route focused and avoid approaching suspicious characters.

4

Reset the Power

Flip the breaker as quickly as the interaction allows. Confirm that the lights return before moving away from the panel.

5

Return to Safety

Go directly back to your room, close the door, and resume the night’s rules. Do not remain in the hallway after the objective is complete.

Breaker phasePriorityCorrect decision
Lights tripIdentify the objectiveConfirm this is a required reset
Leaving the roomMinimize exposureExit only after the event begins
Hallway movementFollow the shortest routeTurn left toward the panel
Panel interactionRestore visibilityReset the breaker promptly
After restorationRecover safetyReturn and lock the door

Breaker mistakes to avoid

The most common mistake is treating the breaker run like normal exploration. The hotel may contain a dangerous figure, so every extra second outside the room increases exposure. Another mistake is forgetting the door rule after the power returns. The objective ends at the panel; it does not replace the need for a locked room.

Use the following approach:

  • Memorize the left-turn route before the lights fail.
  • Keep the group informed if playing with others.
  • Move directly to the panel.
  • Avoid unrelated doors and rooms.
  • Return immediately after the interaction completes.

Exit Key and Door Decision Guide

The game eventually provides a key that can be used to leave the hotel. This changes the decision from “Should I answer this knock?” to “Am I ready to attempt the confirmed exit?” Those are different situations and should not be handled the same way.

Confirmed Progression

A key offered for leaving the hotel is a clear progression signal. Use it when you have prepared for the exit and understand that the monsters may still be present.

Door decisions by progression stage

Progression stageDoor policyMain objective
First nightKeep it lockedLearn the hotel rules
Later survival nightsKeep it locked unless an objective requires movementSurvive escalating events
Breaker failureOpen briefly for the reset routeRestore the power
Key receivedUse the confirmed exit option when preparedAttempt to leave the hotel
Unclear voice or knockKeep it lockedAvoid an unidentified threat

The exit key is not the same as a random visitor invitation. A knock asks you to make a judgment under pressure. The key represents a direct game objective. Even then, leaving may not be safe, because the hotel’s monsters remain active.

Preparing before using the key

Before choosing the exit, review the room’s current condition:

  • Confirm the key is actually in your inventory or has been handed to you.
  • Make sure the current event has ended.
  • Avoid opening the door for an unrelated visitor.
  • Tell teammates that you are attempting the exit.
  • Keep your route focused and do not linger in the hotel.

If the game gives you a choice between staying and leaving, consider whether your group is together and whether an active threat is nearby. The safest decision depends on the current room and hallway state, not only on possessing the key.

A practical decision tree

Use this order whenever the game asks you to interact with a door:

  1. Is this a random knock? Keep the door locked and inspect first.
  2. Is there a strange voice or suspicious behavior? Do not open.
  3. Is the breaker objective active? Open only long enough to reach the panel.
  4. Has the game provided the exit key? Prepare your group and use the confirmed route.
  5. Is the situation unclear? Stay inside until a clear objective appears.

Survival Checklist and FAQ

Use this checklist before ending a night. It covers the rules that most directly affect whether the room remains safe and whether you are ready for the next event.

Final Check

The strongest strategy is controlled movement: stay inside by default, leave only for a clear task, and return as soon as that task is complete.

Essential Night Checklist:

  • Inspect every unknown knock before making a door decision
  • Keep the curtain closed unless a window event requires action
  • Reset the breaker quickly by turning left toward the hall panel
  • Avoid sleeping alone and wait for other players
  • Use the exit key only after confirming the progression objective
