How do you put a spell on you door in Minecraft?

Answer 1

Spell? To open/lock a door in minecraft, it requires you to make a system of redstones that is connected to the door and a button, lever, or a pressure plate

when you click okay it will lock the door or doors if there are two doors next to another.

Same with chests.

If you are worried about people who grief on mutiplayer mode, then you can do the same as a door.

You can lock it by placing a chest or chests ( two together ) by putting a sign above the chest saying

[PRIVATE]

hope this helped.[:
