August Smart Lock App Connectivity Error — Fix Guide

What Does This Error Mean?

An August lock that will not connect from the app usually has a Wi-Fi signal issue, weak Bluetooth, or a stale August Connect bridge. Force-close the app and re-pair the lock if a network reset does not help.

Affected Models

August Smart Lock Pro
August Wi-Fi Smart Lock (4th Gen)
August Smart Lock (3rd Gen)
August Connect Wi-Fi Bridge

Common Causes

Weak Wi-Fi signal at the door (most common)
August Connect bridge offline or unplugged
App outdated or cache corrupted
Bluetooth permission denied on the phone
Lock firmware out of date

How to Fix It

Check Wi-Fi signal at the door.

Stand at your front door with your phone and check the Wi-Fi signal strength. Weak or no Wi-Fi at the door is a common cause of remote control failure. A Wi-Fi range extender or mesh node near the door often fixes the issue.
Check the August Connect bridge.

Older August locks (Pro, 3rd Gen) need an August Connect bridge plugged in within 30 feet of the lock. Verify the bridge is plugged in, has a steady LED, and is connected to your home Wi-Fi.
Force-close and reopen the August app.

Swipe the August app away in your phone's recent apps. Reopen and sign in. This refreshes the connection. Also check for app updates.
Power-cycle the lock.

Remove the batteries from the lock for 30 seconds. Reinsert and let the lock reboot. The app should rediscover it within a minute.
Re-pair the lock if all else fails.

From the app, remove the lock from your account. Reset the lock (long-press the reset button on the back), then add it again as a new device through the app.

When to Call a Professional

August support can troubleshoot account-level issues. Hardware faults (motor not engaging, lock not responding to physical input) may require a replacement under warranty.
