When to Call a Professional
Contact August support if the connection issue persists after multiple reset attempts, if the lock doesn't respond to manual operation, or if you notice physical damage to the battery sled or lock housing. Professional help may also be needed if the lock is hardwired and requires electrical troubleshooting.Frequently Asked Questions
How often should I reset my August smart lock's Bluetooth?
You should only reset the Bluetooth when experiencing connection issues. Regular resets aren't necessary and may require recalibration. Most August locks maintain stable connections for months without intervention.
Will resetting the lock delete my access codes and users?
No, removing the batteries for 60 seconds only resets the Bluetooth radio. Your access codes, user permissions, and lock settings are stored in the August cloud and will be restored when you reconnect through the app.
My August lock still won't connect after the battery reset. What's next?
Try updating the August app, restart your phone, check if your phone's operating system needs updates, and ensure you're within 10 feet of the lock. If issues persist, contact August support for advanced troubleshooting or potential hardware replacement.
Can I use my August lock during the reset process?
Yes, you can still use the physical key override during the reset process. However, smart features like app control, auto-lock, and notifications will be unavailable until you complete the reconnection process.
How do I know if my August lock batteries need replacement?
The August app will send low battery notifications, and the lock may exhibit slow operation or intermittent connectivity issues. Most August locks use 4 AA lithium batteries and typically last 6-12 months depending on usage frequency.
