Keep the Door Locked Ending 5: Blood Moon Route

What the Blood Moon Ending confirms

ENDING 5 in Keep the Door Locked is the Blood Moon Ending. The official badge was created on August 21, 2026, making it the newest of the five badge-supported endings. Its short badge text reads Blood Moon Ending and nothing more, which is the same deliberately cryptic format the developer uses for routes that the community still has to map.

The route is unusual because it ties a new visual state — a red-tinted night — to a new story beat rather than to a single visitor decision or a fixed survival length. Treat it as a story chapter that opens once several earlier conditions have already been met. This page collects the verified evidence, the limits of current documentation, and the safest way to test the route without losing the run.

How I Got ENDING 5 (Blood Moon) in Keep the Door Locked

How Ending 5 differs from the older four routes

Compared with Ending 1: survive 10 days, Ending 5 is not a length-based clear. Compared with Ending 2: golden skeleton, it is not a hidden environmental object. Compared with Ending 3: strange grandma key, it is not a single visitor choice. Compared with Ending 4: katana trust, it is not a one-time armed-visitor decision either.

Blood Moon is closer in spirit to a late-game chapter unlock. The community-documented signal is a red-tinted room state that replaces the normal lighting, paired with a new ending beat that the player is expected to play instead of skip. Award counts climbed into the thousands within a day of the badge going live, which strongly suggests the route is reachable from a normal Story run rather than a once-per-account hidden trigger.

Prepare before you chase the Blood Moon

Ending 5 is a poor goal for a first-session player. Build the standard night loop first by reading How to Play, Camera and Door Decisions, and Sanity Guide. Until a calm camera check feels automatic, the red-tinted night will overwhelm your attention and the new beat will resolve before you have any usable notes.

Survive through night five at minimum. Ending 5 has not been documented on day one or day two in any current clip, and the room-state change is far easier to recognise once you already know what a normal night looks like at that stage. If you have not passed the Survive 10 Days milestone, treat Ending 5 as a side experiment on later nights rather than your first run.

Keep the run clean. Do not stack this attempt with Blood Money grinding, Dream Room tourism, or random Easter-egg hunting. One ending question per session is the only way to know whether Ending 5 fired or whether a different event absorbed your input. Log every attempt in the Ending Tracker so success or failure can be matched to a specific run.

Recognise the Blood Moon night

The confirmed visual signal is a red-tinted night. Doors, walls, and the peephole view shift away from the standard warm hotel lighting into a deep red wash. Audio cues are not yet publicly documented, so do not rely on a specific sound to identify the moment.

When the lighting changes, do not assume the door is now safe or unsafe. The red tint is a chapter marker, not a threat level on its own. Threats can and do continue during a Blood Moon night. Treat it the same way you treat a normal night that happens to be lit differently, then look for the new ending beat rather than the threat you are most familiar with.

If the red tint never appears across multiple ten-day runs, your run is not broken — Ending 5 simply did not trigger. Record the run, reset, and try again with the same clean conditions. There is no documented pay-once shortcut and there are no legitimate “Blood Moon generators” or external services. The badge is awarded by the official server only when the in-game trigger is met.

Play the new beat instead of skipping it

When the red-tinted night arrives, the next thing the game offers is a story beat that does not exist on normal nights. The exact scripted sequence is still incompletely documented, but community clips consistently show a new interaction prompt and a clearly framed “stay and play this” decision. Skipping the beat, slamming the door early, or treating it like a generic anomaly will almost certainly prevent the badge from awarding.

The safest behaviour, given current evidence:

1. Stop treating the night as “just another night”.
2. Stay calm and let the new scene play out without trying to rush it.
3. If a prompt appears, follow the on-screen cue rather than guessing.
4. Do not leave the room mid-beat; the trigger is tied to the chapter, not to a separate object you can grab.
5. Keep your Sanity under control so a low-sanity event does not overwrite the moment.

If you are running low on cash, redeem a code from the Codes hub before the attempt. None of the active strings — ROOM!, VISITS8MIL, FREECASH, or FIRST_CODE — unlock the ending, but a healthy cash buffer prevents an unrelated crisis from interrupting the beat.

Threats that can interrupt the Blood Moon night

Every regular anomaly family can still fire on a red-tinted night. Bookmark the Anomalies hub and especially Door Breaker, Shadow Figure, Window Anomaly, and Toilet Anomaly. If any of those escalate into a lethal event during the Blood Moon night, the badge may fail to award even if the trigger technically fired.

Keep the Survive Door Breaker and Banish Shadow Figure checklists ready. Treat the Blood Moon night as a normal high-pressure night with a different lighting filter, not as an invulnerable story mode.

After you earn or miss the badge

If ENDING 5 unlocks, record: the day and night the red tint first appeared, whether a new prompt played, how long you stayed in the room, and whether the badge awarded immediately or after the cutscene. Update the Badge Tracker and the Ending Tracker so the next attempt can match the same conditions.

If Ending 5 does not unlock, do not assume you failed the beat. Record: the day the red tint appeared, the exact action you took at the prompt, the next anomaly that interrupted, and your sanity at the moment. Use that log to isolate whether the failure was a missed prompt, an interrupted cutscene, or a non-triggering night.

Relationship to the other endings

Blood Moon is the newest of the five endings but it does not replace the older routes. Ending 1 (ten-day baseline), Ending 2 (golden skeleton), Ending 3 (grandma key), and Ending 4 (katana trust) are still documented and still award their own badges. Compare them side by side on the All Endings hub page before picking which one to chase next.

A single ten-day run can be expected to award at most one ENDING badge at a time. Do not attempt Ending 5 and Ending 4 in the same night — if you succeed at one, the other is almost certainly locked out by story state. Treat each ending as a separate research goal and rotate them across sessions instead of stacking them.

Quick checklist before your first Blood Moon attempt

1. You have already passed night 5 on a clean run.
2. Your sanity discipline is stable.
3. You know how to banish Shadow Figure and survive Door Breaker without panic.
4. You have redeemed any codes you plan to use before starting.
5. You are not chasing a second ending in the same session.

When all five are green, start a fresh run, focus only on Ending 5, and treat the first red-tinted night as the moment to slow down rather than speed up.
