Keep the Door Locked Beginner's Guide – Anomalies, Endings & Survival Tips

By Money Lord — Founder & Editor | Updated: August 7, 2026

This Keep the Door Locked beginner's guide teaches the nightly door-decision loop, how to cross-check the posted rules against the cameras and peephole, how to survive every named anomaly, how to keep your sanity from bottoming out, and exactly how to unlock all 3 endings — so you make it through the full 10 nights.

How to play: the nightly door-decision loop

Keep the Door Locked🔒 [Anomaly] is a first-person survival-horror game where you're alone in a hotel room after midnight and strangers keep knocking. Some genuinely need help; some are lying to get in. As the game warns, "one wrong decision may be your last." It was created on May 28, 2026 by the group Hotel Room Services, and at our check on August 7, 2026 it had 10,922 players in-game, 4,283,167 visits, 64,564 favorites, and a 90.3% rating (6,297 likes to 673 dislikes) across 20-player servers — strong momentum for a game only a couple of months old.

Everything runs on one repeating loop each night. Your job is never to react to a knock on instinct — it's to verify before you ever touch the lock:

• The door stays locked by default. A visitor knocks or speaks — treat every voice as unproven until you check it.
• Pull up your evidence: check the CCTV/security feed and the room camera with peephole to see who is actually there.
• Cross-reference what you see against the posted hotel rules, which tell you which visitors are safe and which to refuse.
• Pick a response: open, reject, wait, or hide — only open when the camera and the rules agree.
• Handle whatever comes next (a normal visitor or an anomaly), watch your sanity, and roll into the next knock. Survive 10 days to reach the first ending.

The core objective is to survive 10 in-game days. Doing that cleanly is Ending 1, and it's the goal you should aim for on your first serious run before you start chasing the two secret endings.

Reading the rules and using the cameras & peephole

The two systems that keep you alive are the written rules and your viewing tools, and beginners die because they use one without the other.

The rules system is a posted list of hotel rules that defines who is safe to let in and how you're expected to behave. Read them at the start of a night and re-read them whenever something feels off, because ignoring a rule is what turns a routine encounter into a failed one. A visitor who breaks a rule — being somewhere they shouldn't be, appearing when the rules say no one should — is a threat no matter how friendly they sound.

Your dual viewing tools are how you gather proof. You have a CCTV/security feed that shows the corridor and surrounding areas, plus a room camera and a peephole for a direct look at whoever is right outside the door. The winning habit is to cross-check the camera against the door-view for mismatches: if the peephole shows one thing and the security feed shows another — or shows something that shouldn't be there at all — that contradiction is your warning to reject or hide rather than open.

Every anomaly and how to respond

Beyond ordinary visitors, the night throws named anomalies at you. Each has a specific correct response, and guessing wrong costs you the run. Here's every anomaly to learn:

The through-line across all of them is that a knock is not your only danger. The Room Hider and the Window and Toilet anomalies all originate inside your space, so a beginner who fixates only on the peephole will miss the threat forming behind them. Sweep the whole room between knocks, keep the baseball bat handy for the pizza rat, and remember the door is only one of several ways a night can go wrong.

Managing your sanity (and what pizza does)

Your sanity meter is a second, silent fail condition. It drains over the course of a night, and if it hits zero you lose — the same result as opening the door to something you shouldn't have. That means you can play the door decisions perfectly and still end a run by neglecting the meter.

The counter to that is pizza. Eating a pizza restores roughly 150 sanity, so keeping one on hand is how you push through the tense, draining stages — like a Window anomaly climbing toward stage 3, or a long night of back-to-back knocks. Pizza also ties into a decision path: if a hungry visitor asks for food, giving them 150 is the "Kindness" route, so weigh whether you'd rather spend that on your own sanity or on the visitor.

Making money and what it's for

Keep the Door Locked also has a money economy: you accumulate cash as you play. That cash is your progression currency and gives you a reason to keep surviving nights beyond simply not dying. The pizza that restores your sanity and doubles as the "Kindness" gift is the clearest example of an item that matters to your run, so managing what you spend — on yourself versus on visitors — is part of playing well.

For a new player, the money layer is secondary to survival: your first priority is always to reach Ending 1 by lasting 10 days. Once you're comfortable with the door loop and the anomalies, the cash you bank gives you more room to make generous choices, like taking the Kindness path with a hungry visitor instead of hoarding pizza for yourself.

All 3 endings and how to unlock each

There are three distinct endings, and only one of them is the straightforward survival win:

• Ending 1 — Survive 10 days. The main goal. Make it through all 10 in-game nights by correctly deciding who to let in, handling every anomaly, and never letting sanity reach zero. Aim for this first.
• Ending 2 — Find the golden skeleton. A hidden collectible ending — locate the golden skeleton to trigger it.
• Ending 3 — Accept the strange key. The strange grandma offers you a strange key; accepting it leads to this ending. There is also a special Dream Room state tied to the game's stranger side.

The important beginner takeaway is that the two secret endings involve choices you wouldn't normally make — accepting an item from an odd visitor, or hunting down a hidden object — whereas the safe, repeatable win is simply surviving the full 10 nights. Learn Ending 1 cold before you deliberately chase the others, because the same caution that gets you the golden skeleton or the strange key can also get you killed if your fundamentals aren't solid.

On the subject of shortcuts: Keep the Door Locked currently has no working codes as of August 7, 2026, and doesn't expose a redeem box. Any "code list" you find is almost certainly recycled from LSPLASH's DOORS — a completely different game — so never paste those in. If a real system ever launches, we'll verify and list every code on our Keep the Door Locked codes page.
