Lockette is a plugin we're using instead of LWC. It's used to lock your chests, containers and doors so you can control who has access to it.
How to lock Chests/Containers
To use, simply place a sign on the ground directly beside a chest or other container to be locked. Enter [Private] as the first line. Your own name will automatically be entered on line 2 as the chest owner. Optionally type in the full names of two other users allowed to access the chest's inventory on lines 3 and 4.
If you've done this correctly, the sign will automatically fix itself to the side of said container. Only the chest's owner can then break the sign or chest.
Additionally, you can enter [Everyone] on lines 3 or 4 instead of a user name to allow everyone access to the contents of a private container, or [Operators] to allow ops access. If a Permissions plugin is available, you can use groups like [Moderator] or [Admins] or others as defined in the Permissions settings files.
The owner of a container can add more users by placing additional signs beside the container with the heading [More Users], where lines 2-4 specify the names of the additional users. You can edit the users on previously placed signs by right clicking the sign, and using the command below to change it.

How to lock Doors
To protect a door, you can use the same method as protecting a container, the sign will attach to the door automatically. In addition, you can attach a [Private] wall sign to any side of the blocks just above or just below a door. For double doors only one side needs a sign. Door support is enabled by default in the config file.
Once a door is protected it will only open for someone listed as a user, and will not respond to redstone power or switches unless [Everyone] is listed as a user. Iron doors which usually won't open from clicking will work just as wooden doors. In addition, double doors will open together automatically!
You can also use [More Users] signs as with containers, with the caveat that the sign cannot be placed on the block above the door if the [Private] sign is not above the door as well! This is done to prevent a security uncertainty issue.
Protected doors will be closed automatically if a timer is set. A timer can be set globally with a configuration option, or individually for each door by using the tag [Timer: #] on line 3 or 4 of the [Private] sign, where # is the number of seconds that the door should remain open. If the timer is set to 0, this means the door will never automatically close. If no timer is specified, protected doors will use a global timer set in the configuration file. If the server is shut down cleanly any open doors will be closed, but in the event of a server crash while a door is open, it may remain so. Note that the initial state of a door is assumed to be closed.
Care must be taken to place protected doors on a stable block. Building a door on sand, gravel, leaves, TNT and etc are allowed by the plugin, but cannot be secured fully. Additionally, it should be noted that most status messages still refer to locked blocks as containers, so for the purpose of simplicity, doors should be considered as a type of container.
