Lock any container with a key crafted from copper and iron. Share access by duplicating keys for trusted players. Forgotten locks rust away on their own so nothing stays sealed forever.
Keys are the heart of the lock system. They're crafted from a copper ingot and an iron ingot, and start out blank until you use one on a container.
You can lock any container: chests, barrels, furnaces, brewing stands, and more. The key is consumed when used.
Only the container's owner can produce extra keys. A duplicate key opens the container but can't remove the lock.
permanent access to themselves.Sneak + right-clicking with the copy is what grants persistent access. Without that step, the player needs to keep the key on them.
Only the owner can remove a lock. Doing so returns a fresh blank key and invalidates every duplicate.
Locks left untouched eventually rust away. This stops abandoned or forgotten locks from blocking containers forever.
