Manual & installation
Open the official WL01 user manual
Confirm WL01 on your lock or packaging. Check door thickness, backset, lock orientation and mounting clearance against the manual before installation. Use the components supplied with your version.
Keep the door open for initial setup and test the keypad, enrolled fingerprints, inside thumbturn and mechanical key before closing it.
App & Wi-Fi setup
Use the app QR code and instructions provided with your WL01. This model uses the Tuya platform; follow your supplied manual for the correct app and device-addition procedure.
Prepare a 2.4 GHz Wi-Fi network and check the signal at the door. Remote app access needs the lock to remain connected to the network.
If pairing fails, tell support your app name, phone type, network band and the exact error message. Do not follow another model's reset sequence.
Battery & backup access
- WL01 uses 8 AA batteries. Follow the polarity markings and replace batteries as a matching set.
- Act on low-battery warnings promptly and keep the physical key accessible outside the locked property.
- Follow the manual for emergency power. An emergency supply is not a substitute for replacing depleted batteries.
Common checks
The lock works with the door open but not closed
Check the latch and strike alignment using the installation guide. Do not force the mechanism; send support photos if the fit is unclear.
App access is unavailable
Check whether the issue affects only remote operation or also the local keypad and key. Share the connection status and any error message with support.
Reset or access changes
Use the WL01 programming instructions. Ask support before resetting if existing user access needs to be preserved.
