Crafting a Key


1.15 - 1.20.4

Take a look at the new version of this Data Pack

Lock your Chest to protect your items from other players and Creepers. Shift right click on the Chest to lock or unlock it. You can only unlock the Chest if you originally locked it. It doesn't matter which Key you use.

Even if something destroys the Chest or a Hopper is placed under the Chest, your items can't be stolen. However, be aware that items you put a locked Chest with a Hopper will drop out when you unlock it.


Key Recipe

The Crafting Table will show a Gold Nugget as result, but you will get the correct item after you take it out.

[1.16+] You can repair your Key, if you drop a Gold Ingot with the Key on an Anvil. To get more durability you can also enchant it with Unbreaking.

Observer Addon

Use this add-on to automatically unlock the locked Chest if you are in a radius of 2 blocks.
