Locks, Keys and Lock-Picking

Certain brick, vehicle, backpack and container inventories can be locked, preventing other players from being able to open and make changes to that inventory.

Locks & Security Levels
An inventory can be locked and unlocked by adding / removing a lock item from an inventory's "lock slot" (marked with a lock icon). Inventories can also be unlocked simply by having the corresponding key item (which has the same combination as the lock) in your player or backpack inventory, or in a container you're carrying, when the inventory is accessed.

Players can attempt to pick an inventory's lock (mentioned in detail below); each lock has a different number of "tumblers" for a player to pick. The more tumblers a lock has, the more difficult it will be to pick. A list of each lock's security is listed below: Note: Locks only prevent players from opening inventories; if you lock an inventory while another player is viewing it, they can still make changes until they close the GUI.
 * Blacksteel - 7 Tumblers (most secure).
 * Bronze - 5 Tumblers.
 * Gold - 2 Tumblers (least secure).
 * Iron - 4 Tumblers.
 * Silver - 3 Tumblers.
 * Steel - 6 Tumblers.

Lock-Picking
If an inventory is locked, and if you have a lockpick item in your player inventory, backpack or in a container you're carrying, you can attempt to pick that lock; only one lock can be picked at a time.

Each lockpick in your inventory gives you one opportunity to guess the combination of that lock - you can attempt to guess the numerical combination by moving the vertical sliders (representing tumblers) to any value between 0 and 9. If you guess incorrectly, your lockpick will "break", and one item will be removed from your stack of lockpicks. You will also be notified how many characters / digits you guessed correctly, but not which specific digits were correct. Lock-picking then becomes a type of puzzle or minigame; different locks will have a different amount of tumblers / characters to guess.

Assigning Combinations
By default, locks don't have any combination applied to them. You can however add your own, unique combination to locks and keys by using the Locksmith Table. You can also add the same combination to various keys and locks, just encase you need spares.
