|Link Set-up Info|
|From||A door or object that is controlled by an external lock|
|To||A lockbox, or some other type of external lock|
|Data||Optional. Very useful for a door with two lockboxes|
This link is used to make an object (like a door) only open when it’s lock (like a lockbox) is unlocked.
If there are two lockboxes (e.g. one on either side of a door), the door will need a Lock link to each of them, with a link data value of 1. This will ensure that unlocking either lockbox will unlock the door. If the link data is not specified, the door won’t unlock until both lockboxes have been unlocked.
