To avoid losing your belongings or, even worse, having them stolen in Minecraft PE, consider using the Lockable Chests modification. The creator has taken a very responsible approach to developing this mod.
Features of the Lockable Chests Mod
In Minecraft, you’ll find this unique chest. It cannot be broken, “mined,” or opened. The /kill command will not work on it. Access can only be granted with two items: a key card of the corresponding color or a recognizer. You can change the textures by using dyes.
Key Card. Change its color in Minecraft to match the icon color on the chest for unlocking purposes.
Key Recognizer. Just in case you want to prevent others from crafting key cards in the game, feel free to utilize this tool. No one but you will be able to unlock the chest.
Special scissors. With the chests in Minecraft BE becoming indestructible, a tool will be needed to break them when necessary. Only the player who created the chest can use these scissors on it. Any other user will just waste their time.
To ensure that the mod functions correctly, make sure to enable experimental gameplay features.
