Quick answer
Guide to Keep The Door Locked anomaly reports in Roblox, with patch-sensitive notes for costs, counts, and counters.
Surviving the Night: What Is Keep The Door Locked?
If you've spent any time in Roblox's horror scene lately, you've probably stumbled across Keep The Door Locked — a tense, first-person survival horror experience that drops you into a dingy hotel room and dares you to make it to sunrise. At the heart of the gameplay is the Keep The Door Locked anomaly system, which throws increasingly bizarre and terrifying threats at you throughout each night. Understanding each anomaly type is the difference between surviving and becoming another missing guest in the hotel's long list of casualties.
The game draws clear inspiration from indie horror hits like No, I'm Not A Human, tasking you with identifying which visitors at your door are real people seeking shelter and which are anomalies hungry for your soul. The front desk clerk — your only lifeline — makes one thing abundantly clear: keep that door locked, trust no one, and whatever you do, don't die. According to community reports, most players don't survive past the first night, making knowledge your most powerful weapon.
How the Anomaly System Works
The core gameplay loop revolves around monitoring your hotel room through a laptop camera system, a peephole, and direct observation. Throughout each night, visitors arrive at your door. Some are legitimate guests who need a place to sleep; others are anomalies disguised as humans. Your job is to separate the safe from the deadly using the tools at your disposal.
The front desk provides nightly instructions that change based on which anomalies are active. One night you might be warned about a knife-wielding wanderer; the next, you'll hear about something translucent roaming the halls. Each Keep The Door Locked anomaly requires a specific countermeasure, and failing to respond correctly — whether that means locking the door, hiding under the bed, or resetting a breaker — results in a swift game over.
Key Survival Tools
| Tool | Location | Primary Use |

| Curtains | Window | Monitor and reset Window Seeker |
| Breaker Box | Hallway (turn left from room) | Restore power during outages |
| Bed | Room center | Hide from Door Breaker; stand on it during Vent Ghost events |
Complete Anomaly Reference Guide
Below is the commonly reported anomaly roster, broken down by type and countermeasure. Player experience indicates that anomalies become more aggressive the longer you survive, but exact counts, costs, timers, and ending rules are patch-sensitive.
Door Visitor Anomalies
These anomalies appear at your door disguised as guests. Use your laptop camera to inspect them before deciding whether to open up.
| Anomaly | How to Identify | Countermeasure |
|---|---|---|
| Translucent Guest | Guest appears see-through on camera | Lock the door |
| Doppelganger | A duplicate of the guest is slumped against the wall beside them | Lock the door |
| Dead Doppelganger | A dead version of the visitor lies near the stairs | Lock the door |
| Spasming Limbs | Guest's limbs flail uncontrollably | Lock the door |
| Long Limbs | Guest has unnaturally long arms | Lock the door |
| Neck Craner | Guest stares at the ceiling with neck craned backward | Lock the door |
| Headbanger | Guest smashes head against door violently when viewed through peephole | Complete the quick-time event |
| Knife Killer | Man with a knife appears at door | Turn off lights before sleeping that night |
| Silent Lady | Tall, gaunt woman stares silently | Look at her through cameras (triggers jumpscare but she leaves) |
| Roach King | Giant cockroach asks for pizza | Community-tested: giving pizza is safer than refusing; exact slice cost is patch-sensitive |
Environmental and Room Hazards
Not every threat comes knocking at your door. Some anomalies spawn inside your room or trigger based on environmental conditions.
| Anomaly | Trigger Condition | How to Survive |
|---|---|---|
| Window Seeker | Periodic moans, knocks, and scratching from window | Community-tested: open curtains and look at him to push him back; timing is patch-sensitive |
| Door Breaker | Gaunt white creature charges the door | Hide under the bed until he leaves |
| Spiders | Random ceiling spawns with egg sacs | Avoid standing beneath them when they explode |
| Shadow Man | Appears in corner of room watching you | Shine flashlight at him until he vanishes |
| Vent Ghost | Triggers when answering the door | Stand on the bed and wait for him to crawl back into the vent |
| The Darkness | Random event while standing in room | Follow the lights to reach a doorway back to reality |
| Bathroom Monster | Activates if you sleep alone | Always have at least one non-anomaly guest sleeping in your room |
| Room Hider | Figure spotted while looking around room | Look at him for the jumpscare, then he departs |
| Hacked Laptop | Blocks camera access with a decode message | Restore functionality; exact payment is patch-sensitive |
| The Cake | Lone cake on a trolley visible through door | Actually safe — open the door, eat the cake, and regain Sanity |
Night-by-Night Survival Strategy
The front desk clerk's warnings escalate each night, and the game makes no secret that things get worse the longer you stay. Here's a strategic breakdown of what to expect and how to prepare.
Night 1: Learning the Ropes
Your first night is essentially a tutorial disguised as a nightmare. The front desk walks you through the basics: keep the door locked, check the peephole before opening, and keep the curtains closed unless the window starts tapping. If the power cuts out, sprint to the breaker box in the hall — turn left out of your room — and flip it back immediately.
Key priorities:
- Memorize laptop camera controls
- Practice the curtain-check rhythm for Window Seeker
- Never sleep alone — the Bathroom Monster will get you
Night 2 and Beyond: Escalation
The clerk's tone shifts from cautiously helpful to genuinely surprised you're still alive. New anomalies begin appearing in combination, forcing you to manage multiple threats simultaneously. You might be dealing with a translucent guest at the door while spiders spawn on your ceiling and the Window Seeker inches closer to breaking through.
| Night | New Threats Typically Encountered | Difficulty Spike |
|---|---|---|
| 1 | Translucent Guest, Window Seeker, Bathroom Monster, Breaker outage | Low — learning mechanics |
| 2 | Doppelganger, Shadow Man, Knife Killer, Door Breaker | Medium — multi-tasking required |
| 3+ | Vent Ghost, The Darkness, Headbanger, Hacked Laptop, Roach King | High — rapid threat switching |
Sanity Management
Your Sanity stat degrades from spider explosions, jumpscares, and prolonged exposure to anomalies. Without sufficient Sanity, you become more vulnerable to certain events. The cake anomaly — yes, the Portal reference — is one of the few ways to restore Sanity, so don't be afraid to open the door when you spot that dessert trolley.
Advanced Tips From the Community
Experienced players who have survived multiple nights have shared strategies that go beyond the basic rule set. Here are the most effective approaches:
- Develop a checking rhythm: Regularly cycle through laptop camera, window curtain, and room corners so you catch the Window Seeker and Shadow Man before either threat escalates.
- Keep spare cash reserved: The Hacked Laptop anomaly can strike at the worst moment, blocking your camera access right when you need to identify a visitor. The exact recovery cost is patch-sensitive.
- Pizza is bait, not just a snack: If you purchase pizza, the Roach King may appear. Decide beforehand whether you're willing to give up food, because refusing is reported to trigger a cockroach swarm.
- Memorize safe guest behaviors: Legitimate guests don't have duplicates, dead versions, translucent bodies, or unusual limbs. If anything feels off, lock the door and wait.
- The front desk calls are clues: When the clerk mentions a knife wanderer, translucent figure, or window anomaly, that's your warning to prepare for a specific threat that night.
Frequently Asked Questions
What happens if I open the door for a Keep The Door Locked anomaly?
Opening the door for an anomaly typically results in a failed run according to player walkthroughs. The main reported exceptions are the cake event and the Roach King pizza interaction, but exact outcomes can change after updates.
Can I survive without using the laptop camera?
Technically possible on early nights, but highly discouraged. The laptop camera is your primary identification tool for door anomalies like the Translucent Guest, Doppelganger, and Dead Doppelganger. Without it, you're guessing, and guessing wrong can end the run. The Hacked Laptop anomaly specifically targets this tool, which is why keeping spare cash in reserve matters.
How many nights do I need to survive to escape?
Based on player experience and the front desk clerk's dialogue, you receive a key to leave the hotel after surviving several nights. However, the clerk warns that the monsters aren't going anywhere even if you leave — suggesting the escape is more of a narrative endpoint than a clean getaway. The real challenge is simply surviving each night as the anomalies stack and intensify.
