JustAVaultUnlockKey
Utilizing Repeatable Trial Vaults, this mod adds a dedicated key to unlock Trial Vaults which is crafted from regular keys.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This mod simply adds a key (texture by Milkev) which is used to unlock trial vaults so you can obtain their loot again. You can easily craft this key 1:1 from a regular trial key, and 1:4 from an ominous key. The recipe is also easily changable with datapacks if you wish to modify the recipe yourself!
