Last updated: 10th August, 2026 - Added new Anomalies!
The summer of Anomaly hunting (I'm coining that now) continues with one of the latest horror games to hit Roblox, Keep That Door Locked. This one is seemingly very inspired by last year's indie hit, No, I'm Not A Human. You're hanging out in a dingy hotel room that just can't seem to stop getting visitors. Unfortunately, some of them are spooky Anomalies who want to slurp down your soul, and your job is to prevent them from getting inside while letting in regular ol' guests who need a place to stay. And before you ask, yes, of course you have to let the weirdos roaming a hotel at 2 am in. Otherwise the demon living in your bathroom will chomp on your bones, duh!
To help you sort the ghouls from the late-night cold callers, we've assembled a full list of all the Keep The Door Locked Anomalies below, so you can survive with knowledge on your side.

Window Seeker
Anomaly evidence
Periodically throughout the night, you'll hear moans, knocks, scuffling and scratching from outside the hotel window.

Unchecked, the Window Seeker will grow stronger over multiple phases, getting closer to your window, eventually resulting in a game over if he reaches you
Method of removal
To reset the Window Seeker to phase 1, you'll need to open the curtains and look at him, forcing him to flee. You'll have to keep doing this for the rest of the night, so remember to keep checking!
