1. Weak Wi-Fi connection. Please ensure the network connection is good and there is no barrier or radio interference between your lock and your router, causing unstable network.
2. Please make sure your device is running on the latest firmware.
3. Meanwhile, for smart lock DL03, DL04, DL50FVS, you can try enabling Power-saving Mode in device Settings>Battery to reduce battery drain.

If you are experiencing an issue where the smart lock can be opened from the outside without using a fingerprint or passcode, please remove the front panel, rotate the square rod 90 degrees and try again. We recommend not securing it with screws immediately after installation; instead, wait until you have tested that all components are functioning properly before tightening it. If you still have further concerns, please contact our support team for further assistance.
