Keydbcfg Makemkv
appendonly no
MakeMKV does not automatically look for this file in your Downloads folder. You must place it in the application’s internal data directory.
Note: If the .MakeMKV folder doesn't exist, launch MakeMKV at least once to generate it.
Even with the files in place, things go wrong. Here is the troubleshooting flowchart.
If you prefer to use a local file (or if you have downloaded a specific KeyDB.cfg file manually), here is how the configuration file is structured.
Note: You cannot simply copy-paste random text; you need the actual keys inside this file. However, if you are creating or editing the file manually, the format must look like this:
Filename: KeyDB.cfg
File Structure Example:
; KeyDB configuration file for MakeMKV
; Format: KEY = <Key_Hash> / <Disc_Id>
; Example Entry (This is not a real key):
KEY = 0102030405060708090a0b0c0d0e0f1011 / DISC_ID_EXAMPLE_12345
; Real keys are hex-strings usually 128 characters long
; KEY = <128_char_hex_string> / <Volume_ID>
Where to place the file:
If you download a pre-made KeyDB.cfg file from a community source, place it in one of the following directories depending on your Operating System:
replica-read-only no
Apply with keydbcfg:
keydbcfg set maxmemory 4gb
keydbcfg set appendonly no
systemctl restart keydb
MakeMKV can automatically update its keys by pointing to an online repository. This is the preferred method as it keeps the keys current without manual file replacement.

For most users, Option 1 is the best solution. Using the URL https://keys.vlcmp.net/keydb/ ensures MakeMKV can decode UHD Blu-rays and newer standard Blu-rays without needing to manually download new config files every few weeks.
While MakeMKV primarily uses its own internal system of "hashed keys" to decrypt Blu-ray and UHD discs, it can also use an external KEYDB.cfg file—a community-maintained database of decryption keys—as a secondary source. This is particularly useful for discs that MakeMKV hasn't yet added to its own server or if you are working offline. What is KEYDB.cfg? keydbcfg makemkv
KEYDB.cfg is a text-based database containing Volume Unique Keys (VUKs) and unit keys for thousands of Blu-ray and UHD titles. While MakeMKV normally downloads updates automatically, adding a manual KEYDB.cfg file acts as a backup to ensure your drive can open specific discs immediately. Where to Place KEYDB.cfg
For MakeMKV to recognize the file, it must be placed in the MakeMKV Data Directory. You can find your specific path by opening MakeMKV and going to Preferences > General > MakeMKV Data Directory.

Because new movies are released constantly, the database needs frequent updates. [SOLVED] Seems makemkv don't see the KEYDB.cfg file
Unlocking Your Media: A Guide to KEYDB.cfg for MakeMKV If you have ever encountered an "unsupported" or "encrypted" disc error while trying to digitize your physical media library, you have likely run into the limitations of automated decryption. While MakeMKV is a powerful tool that often handles decryption behind the scenes, there are times when it needs a little help from a file called KEYDB.cfg. What is KEYDB.cfg?
KEYDB.cfg is a community-maintained text file containing Video Unit Keys (VUKs) for thousands of Blu-ray and 4K UHD discs. While MakeMKV has its own internal system for downloading "hashed keys" automatically when connected to the internet, it can also use this external database file as a fallback.
Using a manual KEYDB.cfg is particularly useful in two scenarios: appendonly no MakeMKV does not automatically look for
