Symptoms
- App shows a command sent but the lock doesn't move
- Lock works fine with a physical key or keypad
- App shows the lock as online but unresponsive
Likely causes
- CommonWeak Bluetooth or Wi-Fi signal at the doorThick exterior doors and metal components can weaken wireless signals.
- CommonLow battery in the lockSmart locks often warn of low battery, but a nearly dead battery can cause intermittent failures.
- PossibleApp or firmware needing an updateBugs in older software versions can affect command reliability.
- PossibleLock mechanism binding due to door alignmentIf the deadbolt itself is hard to turn manually, the motor may also struggle.
- PossibleHub or bridge device offlineFor locks that route through a separate hub, an offline hub blocks app control.
What to do
- Replace the lock's batteries even if they show partial charge.
- Try controlling the lock from directly next to the door to rule out a range issue.
- Check that any required hub or Wi-Fi bridge is online.
- Update the lock's firmware and the phone app to the latest versions.
- Test whether the deadbolt turns smoothly by hand or with a key; if it binds, the motor may be struggling against the same resistance.
- Restart the lock by removing and reinserting batteries, then retest app control.
Tools and parts
- Fresh batteries
- Smartphone with the lock's app
