I remember freezing at the camera feed as a translucent shape glided down the hallway. My heart hammered while I realized the door wasn’t a problem—my decisions were. You and I both learn faster when a mistake costs a respawn.
On a quiet afternoon I checked the hallway camera and noticed something off before anyone knocked — that small habit saved my run
The hallway camera is your magnifying glass. Treat every motion, shadow, and odd posture as data: a guest with long arms, a second body slumped by the stairs, or a silent woman staring through the door are all cues that change how you play the night.
| Anomaly | How to Identify | What to Do |
|---|---|---|
| Transluscent Guest | The guest appears see-through on the security camera. | Lock the door. |
| Doppelganger | A copy of the visitor appears slumped against the wall beside them. | Lock the door. |
| Dead Doppelganger | A dead version of the visitor appears in the hallway near the stairs. | Lock the door. |
| Window Seeker | Hear moans, knocks, scuffling, or scratching from outside the window. | Open the curtains and look at it. |
| Door Breaker | A gaunt white creature runs to the door and starts breaking in. | Hide under the bed until it leaves. |
| Spiders | Spiders with large egg sacs appear on the ceiling. | Avoid standing underneath them when they explode. |
| Shadow Man | A shadowy figure appears in the corner of your room. | Shine your flashlight at it until it disappears. |
| Knife Killer | A man carrying a knife appears at the door. | Turn off the light before sleeping. |
| Silent Lady | A tall, gaunt woman silently stares at you from the door. | Look at her through the security cameras. |
| Vent Ghost | A dishevelled man drops from the vent and crawls around your room. | Stand on the bed until he leaves. |
| The Darkness | A pair of hands covers your eyes and transports you to a dark void. | Follow the lights until you reach the exit. |
| Bathroom Monster | A monster lives in the bathroom and attacks if you sleep alone. | Have at least one innocent resident sleep in your room. |
| The cake is a lie | A lone piece of cake appears on a trolley outside the door. | Open the door and eat it to recover Sanity. |
| Hacked laptop | A message says your laptop has been hacked and blocks the cameras. | Pay $300 (€276) to decode the laptop. |
| Spasming limbs | A visitor arrives with limbs that violently spasm and flail. | Lock the door. |
| Long limbs | A visitor has unusually long arms. | Lock the door. |
| Neck Craner | A visitor arrives with their neck bent backward while staring at the ceiling. | Lock the door. |
| Room Hider | A figure appears hidden somewhere inside your room. | Look at it to trigger the jumpscare and make it leave. |
| Headbanger | A visitor repeatedly smashes their head against the door. | Complete the quick time event. |
| Roach King | A giant cockroach appears when you have pizza and asks for some. | Let it in and sacrifice five slices of pizza. |
Transluscent Guest
I first learned to distrust “normal” silhouettes after seeing a guest go see-through on camera. If the body is ghostly, lock the door and don’t give it a second chance.
Doppelganger
One afternoon I watched the hallway feed and spotted a second copy slumped against the wall. When the camera shows a duplicate, treat the visit as hostile—close the door immediately.
Dead Doppelganger
There’s a chill to seeing a corpse in the corridor beside a living guest. Spot a body near the stairs on the feed and seal the door; that one’s not negotiable.
Window Seeker
On the street a stray animal scratching at a window will give you the same warning as this Anomaly: noises matter. If you hear moans, knocks, scuffling, or scratching outside your window, open the curtains and stare it back into phase one until it stops returning.
Door Breaker
I’ve had a Door Breaker shove at my frame until the whole room shook. When the game tells you to hide, get under the bed and stay silent until the creature leaves.
Spiders
Ceiling spiders carry egg sacs that eventually explode; I learned to never stand beneath them. Move out of their blast radius or you’ll lose Sanity quickly.
Shadow Man
The corner of the room is a common hiding spot for the Shadow Man. Turn your flashlight on and hold it on him until he fades away.
Knife Killer
I was halfway through preparations for sleep when I noticed the Knife Killer at the door. If he shows up that day, switch your lights off before you sleep and he won’t get in.
Silent Lady
A tall, gaunt woman who simply stares can rattle your focus. Use the security cameras to stare back and you’ll trigger the jumpscare that removes her.
Vent Ghost
A dishevelled man dropping from the vent walks the floor until he finds the vent again. Stand on the bed and wait him out.
The Darkness
Hands cover your eyes and you drop into a void. Follow the lights ahead of you until you find the doorway back to the hotel.
Bathroom Monster
If you sleep alone and the bathroom creature is active, it can strike. Have at least one innocent resident sleep in your room to prevent it from attacking.
The cake is a lie
I’ve eaten the cake more times than I’ll admit to restore sanity. A lone piece on a trolley is safe—open the door, eat, and recover a chunk of Sanity.
Hacked laptop
The hacked laptop blocks camera feeds with a message. You can pay $300 (€276) to decode it and get your cameras back; most players use in-game cash or trade down-time for visibility.
Spasming limbs
When a guest’s arms and legs flail uncontrollably on camera, that’s your cue to deny entry. Lock the door immediately.
Long limbs
Arms that stretch too far are an easy visual flag. Confirm on the camera, then lock the door.
Neck Craner
The visitor with a neck bent backwards is unnerving for a reason—shut the door if you see that posture on the feed.
Room Hider
The Room Hider is already inside your space rather than outside. Scan the corners and stare at it to trigger a jumpscare that forces it out.
Headbanger
A guest smashing their head against the door triggers a quick time event. Complete the prompt to send them away.
Roach King
The Roach King turns into a voracious landlord demanding five slices when you have pizza in the room. Let it in and hand over five slices, or refuse and watch a swarm enter instead.
How do I identify Anomalies in Keep the Door Locked?
Check the security camera first and treat any odd detail as a threat: translucence, duplicates, odd posture, or a body in the hallway. Use the camera feed and sound cues—your in-game strategy depends on reading those signs fast.
How many Anomalies are there in Keep the Door Locked?
There are 20 Anomalies right now. Players on Roblox, YouTube creators, and Discord guides track changes closely, so if you follow a few reliable creators you’ll spot new ones the week they appear.
I’ve listed every anomaly you’ll meet in-game and the move to make; what did you miss on your last run and which one still makes you jump?
