August Smart Lock Error Code Auto-lock Failed: How to Fix It

Q: Why does my August lock say auto-lock failed?

Auto-lock failed means the DoorSense magnet cannot detect when your door is closed. This usually happens when the magnet is misaligned, dirty, or needs recalibration through the August app.

Q: How do I recalibrate DoorSense on my August lock?

Open the August app, go to Settings > DoorSense, and tap 'Recalibrate'. Follow the prompts to open and close your door several times so the system can relearn your door's position.

Q: Can I use August auto-lock without DoorSense?

Yes, you can enable auto-lock without DoorSense in the August app settings. However, the lock will auto-lock based on time alone, even if the door is open, which reduces security.

Q: How close should the DoorSense magnet be to the lock?

The DoorSense magnet should be within 1/2 inch of the sensor on the lock when the door is closed. Any further apart and the magnetic field may be too weak for reliable detection.

Q: What if my August lock DoorSense magnet keeps falling off?

Clean both surfaces thoroughly, ensure proper alignment, and consider using the stronger adhesive strips included in your August kit. If the magnet continues falling off, contact August support for a replacement.
