- Low batteries (weak motor)
- Deadbolt binding or misaligned
- Calibration off
Problem Description
Your August Smart Lock does not respond to commands from the app or voice assistants. The lock may not lock or unlock when commanded or shows as offline. Auto-unlock may have stopped working. The lock operates manually but all smart features are non-functional. This is commonly caused by Bluetooth issues WiFi bridge problems low batteries or calibration issues.
Why This Happens in Real Homes
An August lock that won't respond splits into two cases: it doesn't react at all (a connection problem — out of Bluetooth range with no bridge, or the bridge offline) or its motor runs but the bolt doesn't move (a mechanical problem — low batteries, a binding deadbolt, or a slipping adapter). Which one you see points at the fix.
If it's unresponsive remotely, confirm the WiFi bridge and lock are online; if it's unresponsive up close, check Bluetooth and re-pair. If you hear the motor but the bolt doesn't turn, replace the AA batteries, make sure the deadbolt throws freely by hand into an aligned strike, and recalibrate so the lock relearns the positions. Most no-response reports are one of these two, not a dead lock.
Symptoms
- Lock ignores app commands
- Fails to lock/unlock
- Spins but doesn't move the bolt
- Delayed response
- Works intermittently
- No response over Bluetooth
- No response remotely
- Motor runs, bolt doesn't turn
Recognize these? Here's what usually causes it.
Common Causes
- Low batteries (weak motor)
- Deadbolt binding or misaligned
- Calibration off
- Bluetooth out of range (no bridge)
- WiFi bridge/lock offline
- Adapter slipping on the thumbturn
- Firmware out of date
- App/lock out of sync
Most fixes happen in the first 3 steps.
Do not force the lock if grinding or stalling. Forcing can strip internal gears. Fix door alignment first before the lock will operate reliably.

Step-by-Step Solution
Replace Batteries
Open August lock face plate and replace all 4 AA batteries with fresh alkaline. Low batteries are the number one cause. Do not mix old and new. Do not use rechargeable NiMH as 1.2V is too low versus 1.5V alkaline. Wait 10 seconds after replacing for reinitialization.

$6.96Check Bluetooth and WiFi Bridge
August app uses Bluetooth when nearby. For remote control the WiFi Bridge must be connected. Make sure phone Bluetooth is on. For bridge unplug 10 seconds and replug. LED should turn solid green. Move bridge within 5 feet of lock and within WiFi range of router.
Recalibrate the Lock
In August app tap lock then Settings then Calibrate Lock. Follow prompts to teach fully locked and unlocked positions. Poor calibration causes stopping short or wrong status reporting. Takes 30 seconds. Repeat after battery replacement.
Adjust Door Alignment
Manually turn thumb turn to test resistance. If stiff the frame is misaligned forcing the motor to work harder. Tighten loose hinge screws. Adjust strike plate so bolt slides freely. Even small alignment improvement reduces motor strain dramatically.

$7.49Fix Auto-Unlock
Auto-unlock needs Always location permission. On iPhone set to Always in Settings. On Android grant Allow all the time and set battery to Unrestricted. Auto-unlock uses geofencing so background location access is essential.
Quick Solutions
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.
Always keep a physical key accessible as backup in case batteries die or lock malfunctions. Never rely solely on smart lock for home access.
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.
