Protecting code locks?

Is there a way to have an unlocked door with code lock that no player can change the code and take the lock or lock it?

Trying to build a spawn point with some doors that are locked and others unlocked all with code locks

 

The hook "CanPickupLock" was implemented for such reasons.

 

possible that this only happens in a zone? sorry, I'm new to modding

 

Code:

// Variable for our permission
    private const string perm = "pluginname.able";        // This hook is called when the plugin is initialised
    private void Init()
    {
        // Registering the permission stored in our previously declared variable
        // The 'this' key word is the plugins instance, in simple terms: so oxide can assign the permission to your plugin
        permission.RegisterPermission(perm, this);
    }        // This hook is called when a player attempts to use a locked entity
    // aka locked door, locked box, locked toolcupboard
    // the return type is object so we can return a value (to override default behavior)
    // in oxide hooks, returning a value usually always overrides default behavior, but it depends on the hook you're using. http://docs.oxidemod.org/rust/
    // in this case we want to override default behavior so a player can use a locked entity, so we return 'true'
    private object CanUseLockedEntity(BasePlayer player, BaseLock baseLock)
    {
        // checks if the player has the permission previously declared and registered
        // also checks if the player is an administrator
        if (!permission.UserHasPermission(player.UserIDString, perm) && !player.IsAdmin)
            // we return null here so the player hears the typical codelock deny sound etc
            return null;            // we return true here so the player can use the locked entity, if we was to return false
        // they wouldn't be able to use the locked entity (afaik)
        return true;
    }

This will apply for all locked entities on your server however, so add a check to the baseLock maybe. Check who placed the lock, check if the lock is in a zone. etc
