Ominous Chest Lock (& Lock Picking)

Right-clicking a container while holding a named Ominous Trial Key locks it. The lock is tied to the key's name, not to a single player, so a key can be copied or stolen and still open the container. Each player can hold one locked container per key name at a time, while different players may reuse the same name on their own containers, and two players sharing a name can open either container with the matching key. A normal trial key first arms the lock on a successful open, and the next successful open with it consumes the key and permanently frees the container.

An optional lockpicking minigame lets a player open locks without the key. Three lock picks can be crafted, and a pick attempt either plays a random roll or a turn-lock minigame, with Vault sounds giving success and failure feedback. Attempts are counted per pick type under the configured lockout scope, which can be per chest, shared across players, or per player. Failed attempts cost health, with rusty, normal and silence penalty modes at 0.5, 1 and 2 hearts by default, and the silence mode resets after a set number of minutes. The mod runs on Fabric, and Paper is also supported as a server platform, with files for 1.21 – 26.2 and the latest Fabric file 1.3.4 for 26.2 (2026-08-25).
