well i know a plugin that does this but you click the things with a stick what is someones property is locked by someone else? and good plugins that allows people to use commands to lock it and others cant lock it ?
I use LWC There are tons of options, such as locking the door for just yourself, allowing others to also open certain doors/chests, locking them with passwords, and more. Not only can you lock doors and chests, but there are many other things too such as furnaces and more!
