Why Won't My August Smart Lock Lock or Unlock via the App?

Device: August Smart Lock (WiFi, Pro, 4th Gen)

This covers an August Smart Lock that won't work from the app at all — no lock/unlock, offline status, or the app can't reach it. The cause is usually connectivity (Bluetooth range or the WiFi bridge) or the lock needing power or calibration.

Why Won't My August Lock Fully Lock or Unlock?

Device: August Smart Lock (All Models)

Calibration teaches your August lock the exact locked and unlocked positions of your deadbolt's thumbturn. When calibration has issues, the lock over- or under-turns, jams, or reports the wrong state — usually because the deadbolt binds or the thumbturn meets resistance.

Why Is My August Lock Battery Draining So Fast?

Device: August Smart Lock (WiFi, Pro, 4th Gen)

Your August smart lock batteries are draining much faster than the expected 3-6 months.

Why Does My August Smart Lock Keep Unlocking by Itself When I Walk Past

Device: August Smart Lock (August WiFi Smart Lock 4th Gen, August Smart Lock Pro, August Smart Lock)

Your August smart lock auto-unlocks when you walk past the door inside your home or when you are nearby but not approaching the door. The auto-unlock feature uses your phone Bluetooth and GPS to detect when you arrive home and unlocks the door. But the geofence detection is imprecise and triggers from inside the home or from the driveway when you are not going to the door.

How to Install August Wi-Fi Smart Lock

Device: August Wi-Fi Smart Lock (Wi-Fi Smart Lock, 4th Generation)

You are installing the August WiFi Smart Lock (4th Generation) — the compact round lock that connects directly to your WiFi without needing a separate August Connect bridge.

How to Install August Smart Lock Pro

Device: August Smart Lock Pro (Smart Lock Pro, Smart Lock Pro + Connect)

You are installing the August Smart Lock Pro (3rd Generation) — the larger cylindrical lock with a metal body that requires a separate August Connect WiFi Bridge for remote access.

The Pro has Z-Wave Plus built in for SmartThings and other Z-Wave hub integration. Installation is similar to the WiFi model — it replaces only the interior deadbolt assembly — but the Connect bridge adds an extra setup step.
