About this Mod

Simple Locks

Simple Locks is a simple mod that adds locks, keys, and lockpick.

lock

Commands

  • /simple_locks lockpick [enable/disable]

Enables or disables lockpicks. Enabled by default.

  • /simple_locks multiLock [enable/disable]

Enables or disables the ability to lock and unlock multiple locks with a single key (a key can only unlock the locks it has locked). When disabled, one key is bound to a single lock. Enabled by default.

  • /simple_locks keyReset [eneble/disable]

Enables or disables the ability to clear a used key. When enabled, placing a key with a lock ID into any crafting grid will return a blank key of the same material with no ID. Enabled by default.

  • /simple_locks unlock

Unlocks the locked block the player is currently looking at without requiring a key.

Configurations

This mod generates a simple_locks.json file inside the Minecraft config folder. You can make any vanilla Minecraft block—or blocks from other mods—lockable by adding their specific identifiers to this file.

Example:

{
  "lockable_blocks": [
  "minecraft:tnt",
  "minecraft:furnace"
  ]
}

With the configuration above, you can now place locks on TNT and furnaces. You are not limited to vanilla Minecraft blocks; you can add block identifiers from other mods into this JSON file to make them lockable as well.

When a lock is placed on a block and is in the locked state, the block gains the following properties until it is unlocked with the correct key:

  • It cannot be broken.
  • Items cannot be inserted into or extracted from it (e.g., via hoppers).
  • It becomes completely immune to redstone signals.
  • It cannot be moved by pistons.

Note: Adding certain complex or incompatible blocks to this list may cause the game to crash. Proceed with caution when adding modded blocks.

Frequently Asked Questions

Simple Locks server crashes on startup – what to do?

Server lagging with Simple Locks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Simple Locks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
