Product description
My fingerprint didn’t work well or the lock sometimes failed to unlock.
Ensure your fingers are dry and clean, and place them at the center of the recognition area for optimal scanning.
After 5 consecutive errors, the lock will be disabled for 2 minutes. Retry afterward or use the App or backup key to unlock.
Why can’t I lock the door?
Check if the interior knob is in Passage(Unlock) Mode, which keeps the door unlocked.
Switch to Normal Mode to lock via the App, or the door will auto-lock after 5 seconds.
Is installation complex? Do I need a professional?
No professional installation is needed.
Install the lock with a screwdriver in about 15 minutes; it fits most U.S. standard doors.
How can I fix the issue if the battery is dead and won’t charge?
Use a USB-A to Type-C cable or an emergency power supply.
Avoid using a Type-C to Type-C cable, as it may not charge properly.
How is privacy and data security protected?
Fingerprints and app data are stored locally, not uploaded to the cloud.
