You're alone in a hotel room after midnight, and every knock could be your last. The keep the door locked anomaly list below breaks down every fake visitor and creature you'll face, so you can separate real guests from monsters before it's too late. This matters because one wrong decision ends your run instantly, and most new players die before their third shift.
Keep the Door Locked Anomaly List: Core Rules for Spotting Fakes
The game drops you into a hotel room where strangers knock at your door, claiming they need help. Some are telling the truth, but many are anomalies — fake visitors designed to trick you into opening the door. According to community data from the official Roblox page, these creatures use story details that don't match the room, and your job is to catch the inconsistencies before you unlock that door.
Every visitor gives you a story, but the room itself tells the real truth. If someone says the oven is smoking but your room has no oven, that's a fake. If the faucet is leaking but you can see it's dry, that's another red flag. The keep the door locked anomalies follow predictable patterns, which means you can learn to spot them with practice.
Here are the core rules that apply to every encounter: these universal mechanics govern all threats, from the Warden’s patrol to the Lurker’s ambush. Players must always respect the audio cues and door-check timing, as breaking line-of-sight too early or too late often triggers an instant chase. Veterans note that mastering these basics is the only way to survive the later floors.
-
Cross-check every detail — compare what the visitor says against what you can actually see in the room
-
Watch the cameras — some anomalies only appear on night vision or CCTV feeds
-
Listen to the voice — voices that flip between normal and a demonic gravelly tone are always fakes
-
Trust your eyes over your ears — visual inconsistencies are more reliable than audio cues
The keep the door locked creatures you'll meet aren't random. They follow specific behavioral patterns, and once you memorize the tells, you'll spot them from the first sentence. For a deeper breakdown of individual tells, check our anomaly tells guide that covers each visual and audio cue in detail.
Anomaly Classes Organized by Detection Method
This section breaks down every known anomaly type based on community reports and player testing. Remember that this keep the door locked anomaly list is community-reported and may not be up to date, as the developer continues to patch and add new creatures. The data below was last verified in August 2026.
Dialogue Contradiction Anomalies
These are the most common fakes you'll encounter. They tell a story that contradicts what's actually in your room, and catching the contradiction is your only defense. In practice, this means checking the room's layout against the fake's narrative—if it claims a door is open but you see it sealed, trust your eyes. Veterans often pause to scan every corner before acting, since a single overlooked detail can cost you the run.
| Anomaly Type | What They Claim | The Red Flag | Difficulty |
|---|---|---|---|
| Oven Smoke Visitor | "The oven is smoking, let me in to check" | Your room has no oven at all | Easy |
| Leaking Faucet Visitor | "Your faucet is leaking everywhere" | The faucet is completely dry | Easy |
| Color-Shifting Cat | "I brought your cat back" | The cat's color changes between sentences | Medium |
| Wrong Room Visitor | "I left something in this room" | They describe a room layout that doesn't match yours | Medium |
These story mismatch anomalies are the bread and butter of the keep the door locked anomaly list. They're designed to test whether you're actually paying attention to your surroundings rather than just reacting to the visitor's words. The easiest way to catch them is to physically look at the room feature they mention before responding.
Visual-Only Anomalies
Some keep the door locked creatures only appear on specific camera feeds. You might see nothing with your own eyes, but the CCTV or night vision reveals something horrifying. This forces players to cycle through every monitor routinely, since a threat can lurk unseen until you check the right angle. Veterans often mark which cameras show activity, as missing a feed can mean a sudden jumpscare from an entity that never touched the physical room.
| Anomaly Type | Where It Appears | What You See | Threat Level |
|---|---|---|---|
| Ghostly Figure | Night vision only | A translucent humanoid shape standing behind the visitor | High |
| Faceless Shape | CCTV feed | A visitor with no facial features at all | High |
| Distorted Height | Both feeds | The visitor's height changes between camera angles | Medium |
| Extra Shadow | CCTV feed | Two shadows but only one person at the door | Medium |
These visual-only keep the door locked anomalies are why you should never skip checking your cameras before opening the door. Players who rely solely on the peephole miss these entirely, and that's how runs end. The ghostly figure is particularly nasty because it appears only for a split second on night vision, so you need to be actively watching the feed when the knock comes.
Audio and Voice Anomalies
Not every fake visitor looks wrong. Some sound wrong, and if you're not listening carefully, you'll miss the tell. A subtle shift in pitch or an unnatural pause in their knock can be the only clue, especially when you're distracted by the generator's hum. Veteran players often mute the game's music to catch these audio cues, turning sound into your most reliable defense.
| Anomaly Type | Normal Voice | Anomaly Voice | Detection Method |
|---|---|---|---|
| Voice Flip Visitor | Calm, human tone | Demonic gravelly tone mid-sentence | Listen for the shift |
| Echoing Voice | Normal volume | Voice echoes as if in a large room | Listen for reverb |
| Wrong Language | Your language | Foreign language then switches back | Listen for the switch |
| Repetitive Speech | Natural conversation | Repeats the same sentence twice | Listen for exact repeats |
According to player reports on the keep the door locked anomaly list reddit threads, the voice flip anomaly is one of the most missed because it happens so quickly. The voice might sound perfectly normal for the first two sentences, then drop into a demonic growl for just one word before snapping back. If you're not actively listening for it, you'll miss it entirely.
Creature Identification Checks Before You Unlock
The key to surviving is building a quick checklist that you run through every single time someone knocks. Veteran players develop this habit within their first few shifts, and it dramatically reduces deaths. Here's the process that works for most survivors:
-
Check the peephole first — look for any obvious visual distortion or wrong features
-
Scan the cameras — switch to night vision and CCTV to catch visual-only anomalies
-
Listen to the full story — don't interrupt; let them finish so you can catch voice flips
-
Verify one room detail — physically check at least one thing they mentioned
-
Decide and act — open the door or keep it locked, then move on
This five-step process takes about fifteen seconds per visitor, and it's the difference between surviving and becoming another statistic. The keep the door locked anomaly list becomes second nature once you've internalized this routine, because you're not trying to remember every single creature — you're just checking for inconsistencies.
If you want a more detailed breakdown of the identification process, our how to spot anomalies guide walks through each detection method with specific examples. It pairs well with this list because it focuses on the how while this article covers the what.
Keep the Door Locked Anomaly List Reddit: Community-Discovered Creatures
The community has been instrumental in documenting the full keep the door locked anomaly list reddit threads, and several creatures were discovered by players rather than revealed by the developer. According to community testing, some of the rarest anomalies only appear after you've survived a certain number of shifts, which means the list is still growing.
Here are the community-discovered creatures that players have confirmed, each with unique behaviors that demand different survival tactics. Knowing their spawn patterns is crucial, as some only appear after certain doors are unlocked, while others roam unpredictably. Veterans often share these findings to help newcomers avoid wasting their limited flashlight battery on false alarms.
-
The Tall Visitor — appears only on shift 10+, stands unnaturally tall in the peephole
-
The Mirror Twin — claims to be your reflection, but the reflection moves independently
-
The Silent Child — a small figure that never speaks, just stares at the camera
-
The Uniformed Officer — wears a security uniform, but the badge is always backwards
These keep the door locked creatures were all reported by players on community forums, and the developer has confirmed several of them in patch notes. The Tall Visitor is particularly unsettling because it doesn't even try to convince you — it just stands there, waiting. Players report that it never speaks, which is itself the tell, because every real visitor has a story to tell.
For a complete ranking of every creature's danger level, our monster list guide organizes them by threat tier and includes survival strategies for each one. It's the perfect companion to this anomaly list because it focuses on what each creature does rather than just how to identify it.
Survival Strategies for Each Anomaly Type
Knowing the keep the door locked anomaly list is only half the battle. You also need to know how to react when you spot one, because hesitation can be just as deadly as ignorance. Here's how to handle each category:
Handling Story Mismatch Anomalies
When you catch a story mismatch, the correct response is simple: keep the door locked and don't engage. These creatures will often escalate their story, claiming they'll die if you don't open the door, or that they can see something moving behind you. Ignore all of it. The moment you've confirmed a mismatch, the encounter is over — you just need to wait for them to leave.
Handling Visual-Only Anomalies
Visual-only anomalies require you to trust your camera feeds over your own eyes. If you see a ghostly figure on night vision but the peephole looks normal, that's still a fake. The cameras don't lie — they show what's actually there, while your eyes can be tricked. Some players make the mistake of thinking the cameras are glitching, but in this game, the cameras are your most reliable tool.
Handling Audio Anomalies
Audio anomalies are the hardest to catch because they require active listening. The best strategy is to record every conversation mentally and replay it after the visitor leaves. If you noticed a voice flip but already opened the door, that's a run-ending mistake. Practice listening for the demonic gravelly tone specifically, because that's the most common audio tell in the game.
| Anomaly Category | Detection Method | Correct Response | Common Mistake |
|---|---|---|---|
| Story Mismatch | Verify room details | Keep door locked | Opening without checking |
| Visual-Only | Check camera feeds | Keep door locked | Trusting the peephole |
| Audio Anomaly | Listen for voice flips | Keep door locked | Opening mid-conversation |
| Behavioral Anomaly | Watch for unnatural movement | Keep door locked | Assuming it's a player |
The pattern is consistent: when in doubt, keep the door locked. The cost of rejecting a real visitor is minimal — you lose a small reputation bonus at worst. The cost of accepting a fake is your run. Always err on the side of caution, and you'll survive far more shifts than players who take risks.
For more on the real versus fake distinction, our fake visitors guide breaks down the behavioral patterns that separate genuine guests from the creatures wearing their faces. It covers the subtle differences that even experienced players sometimes miss, such as how fakes hesitate before knocking or fail to repeat your name correctly. Knowing these tells can save you from opening the door at the worst possible moment, especially during later nights when mimics grow bolder.
Frequently Asked Questions
How many anomalies are in the keep the door locked anomaly list?
The full list is still being documented, but community reports confirm at least 15 distinct anomaly types as of August 2026. The developer continues to add new creatures with each update, so the list grows over time. Players on the keep the door locked anomaly list reddit threads regularly report new sightings that get verified and added to community documentation.
What is the rarest keep the door locked creature?
The Mirror Twin is currently the rarest confirmed anomaly, appearing only after shift 15 under conditions players haven't fully mapped. Many players finish the entire game without ever encountering it. Community testing suggests it triggers after rejecting a certain number of real visitors, acting as a punishment for being overly cautious.
Can keep the door locked anomalies appear on the first shift?
Yes, the basic story mismatch anomalies can appear on your very first shift. The game introduces them early to teach you the core mechanic, and the difficulty ramps up as you progress. Visual-only and audio anomalies typically appear from shift 3 onward, while the rarest creatures are locked behind shift 10 or higher.
Do anomalies ever appear as multiple visitors at once?
Yes, anomalies can appear as multiple visitors at once, though this is rare and condition-triggered. When it occurs, you must assess each visitor independently, as one may be real while the other is fake. This creates a high-difficulty scenario since opening for one forces accepting the other.
Is the keep the door locked anomaly list the same on every platform?
The anomaly list is the same on every platform, as it is a single game experience. However, mobile players may face slightly different camera behavior, making visual-only anomalies harder to spot. The core creature roster remains identical across all devices.
