For SF-SMARTLOCK-BT locks it is possible for the administrator to manage an unlimited number of locks and the administrator shares them with an unlimited number of users. In other words, the administrator can have almost infinite number of locks, but the user cannot be given access to all locks at once, the invitation must be made one by one.
Example:
admin: lock 1 --> user 1 permissions
admin: lock 2 --> user 1 permissions
