  3. Ensure keys match or exceed your game's firmware requirement.
  4. Restart Yuzu after making any changes to the keys folder.
  5. Clear shader cache if games launch but show visual glitches.
  6. Re-dump keys from your Switch if all else fails.

Detailed Error Solutions

"Encryption keys are missing" error
This is the #1 issue. Yuzu cannot find your prod.keys file. • Verify the file is named exactly prod.keys (lowercase, no .txt extension) • Check it's in the correct directory for your OS • Windows: %APPDATA%\yuzu\keys\ • Linux: ~/.local/share/yuzu/keys/ • Android: /storage/emulated/0/yuzu/keys/ • Restart Yuzu after placing the keys
Keys are present but games won't decrypt
Your keys version is likely older than the game's firmware requirement. • Update your Switch firmware to the latest version • Re-dump your prod.keys using Lockpick_RCM • Replace the old keys file with the new one • Always use the yuzu prod keys latest version
Difference between prod.keys and title.keys
prod.keys contain system-level encryption keys for the Switch. They're needed for ALL games. title.keys contain game-specific decryption keys for individual titles. Some games, especially those with DLC, require these in addition to prod.keys. Always dump both files together for complete compatibility.
Yuzu keys not working on Android
The yuzu prod keys download for Android process uses the same keys as PC, but placement differs. • Path: /storage/emulated/0/yuzu/keys/prod.keys • Use a file manager to create the 'keys' folder if needed • Make sure the file isn't saved as prod.keys.txt (common on Android) • Some file managers hide extensions — check file properties
Black screen after loading a game
This usually isn't a keys issue but rather a shader or GPU problem. • Delete the shader cache (Yuzu → right-click game → Remove → Shader Cache) • Update your GPU drivers to the latest version • Try switching between Vulkan and OpenGL • If only one game is affected, the dump may be corrupted
Keys file is 0 bytes / empty
The key dump failed or was interrupted. • Re-run the dumping tool on your Switch • Ensure your Switch battery is charged (dumping during low battery can fail) • Check the SD card for errors using a tool like H2testw • Try a different SD card if issues persist
Games crash immediately after decryption
Keys are working (game decrypts) but the game itself crashes. • This is typically a Yuzu compatibility issue, not a keys problem • Check Yuzu's game compatibility list • Update to the latest Yuzu build • Try changing CPU accuracy to 'Unsafe' for better compatibility
Can I use keys from a different Switch?
Technically, keys from any Switch of the same firmware version will work identically since all Switch consoles share the same key set per firmware version. However, you should only use keys dumped from your own console to stay within legal bounds.
