Copper Keys
Java mod listed for Minecraft 26.x. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthAdds Copper Keys which you can use to lock chests, doors, and trapways.
Start by making a Blank Key out of two copper nuggets. Right-click that key onto your door or chest to lock it. It will then only be accessible to people that have the key anywhere in their inventory, incl. inside bundles and such. You can copy a key by putting it in a crafting grid with a new blank key.
The key prvents anyone from opening the chest or door, but not from closing it. Additionally, the keys don't prevent anyone from breaking the chest or door, so burglary is still possible. You can also name keys with /keyname or with an anvil. This will also give that name to all key copies.
You need to use the included Resource Pack so the keys get the right appearance, but it's very easy to merge with other resource packs because it's just one item.
