Introduction
Guides is the first stop for every new player in Keep the Door Locked. This category collects complete walkthroughs for the game's core loop: you spawn in a hotel room after midnight, the first knock comes, and everything from there is a test of observation and decision-making. Here you will find controls and settings, a step-by-step first night walkthrough, explanations of your room layout and the monitor, and a full playthrough walkthrough that takes you from spawn to sunrise. We also cover the game's hidden features, secrets and prologue, plus everything you need to know before your first night, so you never freeze when the first stranger knocks.

Popular Guide Paths
The First Knock
The first knock is the make-or-break moment of your opening night, because how you handle that first visitor teaches you the routine that carries the rest of the run. The correct procedure is always the same: open the monitor, cycle through the cameras, check both the hallway and the room interior against the visitor's claims, and only then make a decision at the door. Never touch the lock before the monitor, and if the story checks out but something still feels off, use night vision before unlocking.
Room & Monitor Familiarization
Room and monitor familiarization is the prep work that turns the first night from chaos into routine. Before the visitors start arriving, learn each camera angle, where the blind spots sit, and exactly how the monitor interface behaves. The core skill is fast camera cycling, so you can check the hallway and the room interior within seconds of a knock. The most common beginner mistake is staring at a single view too long while the visitor waits at the door, because time pressure is part of the challenge.
Secrets & Hidden Features
The secrets and hidden features guide collects the parts of the game that are never explained on screen: hidden interactions scattered around the room, unlockable content buried behind specific conditions, and community-found secrets that reward players willing to experiment. Uncovering them takes medium effort, usually a few replay nights and testing unusual choices, but the payoff is access to content and endings most casual runs will never see. It is the completionist's manual for everything the tutorial leaves out.
Speedrun & Completion Routes
Speedrun and completion routes turn the whole game into a plan instead of a reaction, mapping out exactly which knocks to answer and which choices to make. An any% route aims for the fewest possible decisions on the way to a clean morning, skipping everything optional to save seconds and risk. A 100% route plans the visitor choices across multiple nights so you can reach every ending and secret in order. Memorizing which visitors are safe and which are traps means you stop re-reading every story at the door.
Controls & Settings Guide
The controls and settings guide covers the tools you press a hundred times each night: the monitor toggle, the camera cycling keys, the night vision switch, and the lock itself. Knowing these before the first knock keeps your hands automatic when the pressure rises. The guide also covers the platforms, explaining how to remap the camera and lock buttons on both PC keyboard and mobile touch layouts for fast switching. Tuning volume up with headphones is part of the setup too, since several anomalies are caught by ear rather than eye.
Core Mechanics
The core loop of Keep the Door Locked is deceptively simple: a knock sounds, you check the cameras, verify the visitor story, and decide whether to unlock the door. The skill comes from your routine. A good run starts long before a knock — learn the room, understand your camera angles, and know where the monitor puts you at a disadvantage. The walkthroughs in this category teach you the pre-knock routine: survey the room, toggle night vision, and prepare to verify the first claim. They also explain the game's timing — when the first visitor comes, how often knocks repeat, and how your decisions at the door shape what happens at sunrise.
Advantages
Guides give new players the fastest possible path to their first successful night. Instead of dying four times to learn what an anomaly looks like, you can read exactly which tells to watch for and memorize the standard answer-the-door routine before you even load in. The category is also great for returning players chasing completion: each walkthrough covers the small details — settings that make the game easier, secret features, and how to progress further night after night. Because the game is still updated regularly, our guides are maintained to reflect the current version, so you always have up-to-date advice.
Challenges
The main weakness of a walkthrough-heavy category is that it can spoil the tension of the game. If you follow a scripted first-night guide, you already know who knocks, what they say, and what to do — which removes most of the fear the game is built around. Some players also prefer to discover hidden features and secrets on their own, and reading the secrets section first will ruin those surprises. Finally, game updates can change first-night behavior; if the developers rebalance the early game, older walkthrough details may not match the current version until we update them.

Quick Tips
Always check the monitor before the door. Build the habit on night one: knock → monitor → identify → decide. This single routine prevents most beginner deaths because anomalies are most often revealed on camera, not in person. This one habit alone prevents most beginner deaths, and it costs almost no time once the muscle memory forms.
Verify every claim against the room. If the visitor says the oven is smoking, the faucet is leaking, or the neighbor's cat is black, check the claim through the room camera first. Real visitors describe the room correctly; anomalies lie about details that do not exist. Real visitors describe the room they can actually see; anomalies describe the room they imagine. Treat every claimed detail as a test you can pass by watching.
Use night vision on every suspicious visitor. Height, face and form distortions are easiest to see with night vision on. If something looks taller than normal or the face presses against the lens, turn them away immediately. Compare the visitor to the door frame and the hallway fixtures for scale, then decide with full information instead of trusting a first impression.
