Why does my Fob sometimes lock instead of unlock the door?

"Intelligent Locking" is active by default; in other words, the Fob unlocks a locked door and locks an unlocked door. With doors with a knob on the outside, you might (consciously) not lock the door but still want to open the door from the outside. In this case, the Fob will lock the door, because it automatically switches from "unlocked" to "locked". To prevent this action, simply deactivate intelligent locking by the Fob in the Manage Smart Lock menu and specify the desired actions yourself.
