What can I do if my Fob doesn't lock at the push of a button?

First, check whether you can control the Smart Lock from the inside. If you only experience problems from the outside, reinforced door or shielding materials might restrict the reach. The LED signals on the Fob indicate why a locking process was not carried out. If the Fob does not indicate any connectivity errors or if the Fob works properly from the inside, try again after changing the batteries.
