How to Fix FNAF Secret of the Mimic Door Not Opening Bug

One of the most frustrating experiences in gaming is when a crucial mechanic fails to work, halting progress entirely. In Five Nights at Freddy's: Secret of the Mimic, players have encountered a persistent issue where an automatic door refuses to open, preventing them from advancing further.
This bug occurs early in the game when players attempt to enter Murray’s Costume Manor. After progressing through the initial task, a door labeled "Show Starting Soon" should open automatically—but for many, it remains shut. If you're stuck, don’t worry. While an official patch is reportedly in development, several effective workarounds have helped players bypass this glitch.

Why Does the Door Bug Happen in FNAF Secret of the Mimic?

Before diving into fixes, it helps to understand potential causes:

• FPS-Related Glitches: The game’s mechanics are tied to frame rate, and unlocked FPS can disrupt event triggers.
• V-Sync Interference: Improper synchronization between frame rate and monitor refresh rate may cause timing issues.
• Corrupted Game Files: Installation errors or save file corruption can prevent scripted events from activating.
• Hardware Limitations: Running the game on an HDD or with insufficient storage may lead to loading errors.

Tested Fixes for the FNAF Secret of the Mimic Door Bug

1. Lock FPS to 60

Since gameplay elements are frame-rate dependent, uncapped FPS can break triggers. Follow these steps:

• Open the game’s graphics settings.
• Enable the 60 FPS cap if it’s disabled.
• Restart the game and check if the door opens.

2. Disable V-Sync

V-Sync can sometimes desync in-game events. To turn it off:

• Navigate to Graphics Settings.
• Toggle V-Sync off.
• Reload your save and attempt progression again.

3. Lower Graphics Settings

Reducing graphical load can stabilize performance:

• Set textures, shadows, and effects to Medium or Low.
• Restart the game and see if the issue resolves.

4. Reload Your Save File

Sometimes, a simple reset fixes script errors:

• Return to the main menu.
• Click "Continue" to reload your save.
• Check if the door now functions correctly.

5. Start a New Save File

If the bug persists, try a fresh playthrough:

• Create a new game save.
• Progress to the door section again.
• Many players report this bypasses the bug entirely.

6. Reinstall the Game

Corrupted files may be the culprit:

• Uninstall FNAF Secret of the Mimic via Steam or your game launcher.
• Reinstall and launch a new save file.

7. Move the Game to an SSD

HDDs can cause loading delays that disrupt triggers:

• Transfer the game to an SSD or faster storage drive.
• Launch and test if the door opens as intended.

Will There Be an Official Fix?

According to player reports on Steam, developer Steel Wool Studios has acknowledged the issue and is likely working on a patch. Untilthen, these workarounds should help you continue your playthrough.

Final Thoughts

The FNAF Secret of the Mimic door bug is an annoying obstacle, but these solutions have helped manyplayers overcome it. If one method doesn’t work, try another—some fixesare system-dependent. Stay tuned for official updates, and happy gaming!
