Step-by-Step Solution

1

Check and Replace Batteries

Most smart lock issues stem from low batteries. Open the battery compartment on the interior side of the lock. Use fresh high-quality AA or AAA batteries as specified. Do not mix old and new batteries. After installing close the compartment and test the lock. The app should now show a higher battery level.

Recalibrate the Lock

Open the manufacturer app and find your lock settings. Look for Calibrate or Door Handing Setup. Follow the on-screen instructions which typically involve extending and retracting the bolt several times. This helps the lock learn the resistance of your specific door. Proper calibration prevents grinding and incomplete locking.

Check Door Alignment

Close the door and check that it sits flush in the frame without force. The bolt should extend smoothly into the strike plate. If there is friction or the bolt hits the plate, adjust the strike plate position or add a deeper strike box. Misalignment causes motor strain and battery drain.

4

Verify Network Connection

Check if your lock uses WiFi directly or requires a hub. For hub-based locks ensure the hub is plugged in and showing online. For WiFi locks verify signal strength at the door. The lock should show as connected in the app. If offline try power cycling the lock by removing batteries for 30 seconds.

5

Reset Access Codes

In the app go to access code management. Delete any codes that stopped working and create new ones. Use 4 to 8 digit codes as supported by your lock. Test each new code at the keypad. If the keypad itself seems unresponsive, check if it needs separate batteries or cleaning.

6

Update Lock Firmware

Open the lock settings in your app and check for firmware updates. Install any available updates which may take several minutes. Keep the app open and stay near the lock during the update. Updates often fix connectivity issues and add new features. Restart the lock after updating by removing and reinstalling batteries.

Quick Solutions

Replace the batteries with fresh AA's
Check WiFi bridge connection
Recalibrate the lock
Adjust door strike plate
Force close and reopen the app

Still having issues? This is usually the deeper cause below.

If the keypad rejects valid codes, a lockout timer may be running — five failed entries locks most keypads silently for 5–10 minutes.

Pro Tip

Set up low battery alerts in the August app so you get notified before the batteries die completely and you get locked out.

Real-World Insight

Most smart lock failures people label as hardware issues turn out to be a code wiped during a sync, or a setting reset nobody remembers triggering.
