Frequently Asked Questions

Why does my August lock only work sometimes with auto-unlock?
Intermittent auto-unlock issues are usually caused by inconsistent phone permissions, low lock battery, or Bluetooth interference. Check that all app permissions remain enabled and replace batteries if they're below 20%.
How far should I be from my August lock for auto-unlock to work?
The recommended geofence radius is 200-500 meters from your home. You need to leave this area completely and then return for auto-unlock to trigger. Being too close to the boundary can cause inconsistent results.
Can multiple phones use auto-unlock on the same August lock?
Yes, you can set up auto-unlock for multiple phones on the same lock. Each user needs the August app installed with proper permissions and must be added as a user in the lock settings by the lock owner.
Does August auto-unlock work without internet?
Auto-unlock works via Bluetooth and doesn't require internet connectivity. However, you need internet to initially set up the feature and for some advanced functions like remote notifications.
Why won't my August lock auto-unlock when I arrive home?
The most common causes are disabled location services, Bluetooth turned off, geofence radius set too small, or low lock battery. Check all app permissions and ensure you've completely left the geofence area before returning.
