It requires mods. It is not possible in Vanilla.
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 or if you want to lock it you make a sign that says [PRIVATE] 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.[:
This is part of a server plugin called Lockette. Simply select a sign on your hotbar and right-click on the chest you want to lock. The sign will appear with [Private] and your name on it.This doesn't work in single player, or on servers without the Lockette plugin installed.
Shift while you place it.
Left click here you want it to go while holding the door.
you can put up a sign that you can make out of wood and put it at the front of your house
Fill in 6 boxes with planks
You can't. Enchantments are only for tools and armor for now.
All you have to do is put your mouse where you are going to put the door.Then click the left clicker.
Currently, there has been no way or glitch to put a sign on a mine cart. Also, Notch has no plans on making this possible. Maybe contact a modder to make a mod for this?
Put a sign on the door.
Two spaces infront of the house sign is where the door of the house will be, so you can put your paths on the third space in front of the house sign. Hope this helps!
