Keep The Door Locked is a survival horror game built around a simple idea: stay inside your hotel room, follow the safety rules, and figure out which visitors are actually human. The problem is that strange creatures and dangerous events can appear at almost any time.
You will need to decide who can enter, deal with different hotel events, keep your Sanity under control, and survive enough nights to discover what is really happening. This Keep The Door Locked walkthrough explains the basic rules, how to identify anomalies, how to handle important events, and how to unlock all four endings.
Keep The Door Locked Basics
The main objective in Keep The Door Locked is to survive your stay at the hotel. You are given a room and must deal with people who knock on your door throughout the night. Some are normal guests looking for somewhere safe, while others are anomalies trying to get inside.
The game is not simply about refusing everyone. You actually need to allow certain guests into your room because of another threat hiding in your bathroom. At the same time, opening the door to the wrong visitor can lead to a dangerous encounter. Your main tasks are:
- Check visitors before opening the door.
- Allow safe guests inside when necessary.
- Keep an eye on the window.
- Follow the hotel safety rules.
- Deal with random events.
- Maintain your Sanity.
- Survive enough nights to reach an ending.
The game becomes easier once you understand that not every event requires the same response. Some visitors should be allowed inside, while others should immediately be rejected.
Hotel Safety Rules
Early in the game, the hotel gives you a set of safety rules. These rules explain several of the biggest dangers you will encounter during your stay.
The most important rules involve the bathroom monster, suspicious visitors, and the creature outside your window.
Bathroom Monster
The bathroom monster is one of the reasons you cannot simply refuse every person who knocks on your door.
You should never sleep alone. Before going to sleep, make sure a safe guest is inside your room. Having another person there prevents the bathroom monster from attacking you while you sleep.
This means letting a normal guest into your room is not just an act of kindness. It is part of your survival strategy.
Door Knocker
Not every person who knocks on your door is human.
Before opening the door, inspect the visitor carefully. You can use the peephole to get a closer look, while the CCTV camera can reveal details that are harder to notice directly.
If something about the visitor seems unnatural, do not let them inside.
Window Seeker
The Window Seeker is another threat you need to monitor.
If you hear strange tapping or groaning coming from outside your room, check the window immediately. Press F to interact with the curtains and open them.
If the Window Seeker is outside, seeing it will cause the creature to run away. Do not ignore these sounds, because the longer you leave the creature alone, the closer it can get.
How Sanity Works
Sanity is another important mechanic in Keep The Door Locked. Your current Sanity level is displayed at the top of the screen and can decrease when you encounter disturbing events or make certain wrong decisions. Running out of Sanity can make surviving the hotel much harder, so you should try to keep it as high as possible.
There are a couple of ways to restore Sanity:
- Sleep after following the hotel’s safety rules.
- Eat pizza received from the Pizza Man event.
Managing Sanity becomes especially important during some of the later events, particularly when you are sent into nightmare areas where your Sanity can drain continuously.
How to Spot Anomalies
Identifying anomalies is one of the most important parts of the game. Some visitors look normal at first, while others have obvious visual or audio problems.
Always inspect a suspicious visitor before deciding whether to open the door.
Twitching
If a visitor’s head suddenly moves or twitches from one side to another in an unnatural way, this is a major warning sign.
Normal guests should not behave like this, so it is safer to keep the door locked.
Strange Voice
Pay attention to how visitors sound when they speak. A distorted or unnatural voice can indicate that something is wrong.
However, a deep voice by itself does not necessarily mean that the visitor is an anomaly. Look for other signs before making your decision.
Shaking
Visitors who constantly shake while standing outside your door should be treated with suspicion. This unusual behavior can indicate that the person is not a normal guest.
Translucent Visitor
Some visitors may appear normal when viewed through the peephole but look partially transparent through the CCTV camera.
If you receive a warning about a translucent figure and later see someone matching that description, do not let them inside.
Unloaded Texture
One particularly tricky anomaly has a strange visual problem when you first look through the peephole. The visitor may appear to have an extremely low-resolution texture.
The confusing part is that checking again may make the visitor look completely normal. Do not automatically assume the first appearance was a graphical glitch. This can be an intentional anomaly, so unusual texture behavior is worth treating as a warning.
Keep The Door Locked Events
Random events are an important part of your hotel stay. Some are harmless, some provide useful items, and others can become dangerous if you do not react correctly.
Pizza Man
The Pizza Man can appear at your door and offer you a pizza.
If everything else about the event appears normal, you can accept the pizza. It will appear inside your room next to the laptop.
Eating the pizza restores some of your Sanity, making this one of the more useful events you can encounter.
Power Outage
If the lights suddenly go out, you need to leave your room and restore the electricity.
Go into the hallway and look underneath the stairs. You will find the breaker there.
Use your flashlight to help navigate the dark hallway and locate the breaker more easily.
Knife Guy
You may eventually see a dangerous-looking man carrying a knife when you look through the peephole. He resembles a horror movie killer and may quickly disappear.
You do not need to immediately chase or confront him.
Later in your stay, the front desk may contact you about the situation. Pay attention to what happens afterward, as this event can become part of the hotel’s larger sequence of events.
Cat
A woman may arrive at your door carrying a black cat and ask whether the animal belongs to you.
It does not, but you can choose to keep the cat.
If you accept it, the cat stays in your room. You need to provide it with food and water every day.
The cat also provides protection. It can save you from an anomaly attack, although the cat will disappear afterward. It is a useful survival option, but losing the cat is the downside.
Katana Man
A man carrying a sword may arrive and explain that he wants to hunt the Window Seeker. He asks to use your hotel room as his base.
If you allow him to stay, he eventually confronts the Window Seeker. However, the fight results in your window being broken, creating another problem.
You can refuse him if you want to follow a more normal route, but allowing him inside is required for one of the game’s special endings.
Hazmat Crew
Two people wearing hazmat suits can appear and warn you about spiders living inside the hotel’s vents.
They are friendly and can help remove spiders from your room if you allow them inside.
This event is generally safe and can help deal with another nuisance that appears during your stay.
Ceiling Spider
Spiders can sometimes appear on the ceiling of your room.
These are connected to the warning from the Hazmat Crew. If you have bug spray available, you can use it to get rid of them.
Do not ignore the spiders if they appear, especially if you want to keep your room under control.
Roach King
The Roach King is a massive humanoid cockroach that may appear at your door and ask for food.
Despite his appearance, this visitor is relatively harmless. If you allow him inside, he eats some of your pizza before leaving.
It is one of the stranger encounters in the game, but it does not require the same defensive response as some of the hostile anomalies.
Door Breaker
The Door Breaker is one of the events you should take seriously.
When you look through the peephole and see the tall, pale figure with a bald head and large grin, immediately prepare to hide.
The correct response is to hide underneath the bed.
The Door Breaker will smash through the door, search the room, and eventually leave. Staying hidden is the safest way to survive the encounter.
Shadow Man
The Shadow Man can appear inside your room rather than outside the door.
When you see the tall shadow-like figure standing in the corner, take out your flashlight and shine it directly at the creature.
Keep the light on it until it disappears. This should be your priority when the Shadow Man appears.
Dreams
During later nights, sleeping can sometimes trigger a strange dream sequence.
You may find yourself inside an unfamiliar room containing several doors. The correct choice can appear uncertain, and the middle door has been a successful option during these sequences.
Because these dream events can be unpredictable, pay attention to the environment and be prepared for the possibility that the sequence may vary.
Nightmare
The Nightmare event is more dangerous because your Sanity constantly decreases while you are inside it.
You will suddenly find yourself in a dark corridor. Once this happens, do not waste time exploring every area.
Move toward the lights as quickly as possible.
Movement upgrades can make this section easier, but you can still complete it at normal movement speed if your Sanity is in good condition when the event starts.
How to Get Every Ending
There are currently four endings in Keep The Door Locked. Your choices after surviving the first ten nights determine which ending you receive.
Ending 1: Tenth Day Bad Ending
This is the most straightforward ending and one of the easiest to encounter.
After surviving ten days, the man from the front desk eventually appears at your door and gives you a key that supposedly allows you to leave.
Take the key and leave your room.
However, once you enter the hallway, the Door Breaker appears and begins chasing you. You will have to run through a chase sequence, but the route eventually leads to a dead end.
The Door Breaker catches you, resulting in the bad ending.
Ending 2: Skeleton Key Good Ending
The Skeleton Key ending can occur after Day 10.
At some point, you may hear a knock and see a skeleton standing outside your door through the peephole.
Open the door and you will find the skeleton lying on the floor with a key nearby. Take the key.
After obtaining it, use the phone to contact the front desk and ask to leave.
When you reach the exit hallway from the previous ending, do not continue toward the Door Breaker chase.
Instead, look for the door on the left. You should see an interaction prompt labeled Enter Truth.
Enter the door and follow the hallway until you reach a mysterious gold door. This route leads to the game’s better ending.
Ending 3: Weird Granny’s Ritual
The third ending is much worse.
After Day 10, you may encounter an NPC known as Weird Granny. If you allow her inside and accept the key she gives you, you can begin this ending route.
Use the phone to call the front desk and ask to leave, just as you would during the Skeleton Key route.
Once you are back in the hallway, you need to choose the door on the right instead of the left.
This takes you into a dark hallway filled with candles. Follow the path all the way to the end to discover what is waiting for you.
The result is the game’s very bad ritual ending.
Ending 4: Katana Man’s Revenge
The final ending is connected to the Katana Man event.
When the sword-wielding man asks to use your room as his base, allow him inside.
Eventually, the Window Seeker appears outside your window. Katana Man follows through with his plan and attacks the creature through the window.
The encounter results in the Window Seeker and Katana Man disappearing, but your window is left broken.
You can use the broken window to leave the room and follow the resulting route to trigger the special ending.
Unfortunately, escaping through the window does not exactly give you the happy conclusion you might expect.
Keep The Door Locked turns a simple hotel stay into a constant test of observation and decision-making. The safest approach is not always to keep everyone outside, because some normal guests are needed to protect you from the bathroom monster. At the same time, letting the wrong person inside can quickly end your run.
Once you understand the major anomalies and random events, surviving becomes much easier. From there, you can start working toward the different endings, whether you want the bad ending, the Skeleton Key route, Weird Granny’s ritual, or the special Katana Man ending. The key is to pay attention to what the hotel is showing you and avoid assuming that every strange detail is simply a visual glitch.
