If your smart lock being unable to remote unlock, please kindly follow the steps below:

1. Please make sure your smart lock is running on the latest device firmware.

2. Please check and select the time zone for the smart lock again (device Settings>Device information>Time zone).

3. If you are using the DL01S smart lock, please make sure the lock is connected with the A3 gateway via Wi-Fi connection and its keypad as well.

If you need further assistance, please contact the EZVIZ support team for personalized guidance.

Kindly note that the actual battery life will vary depending on environmental factors, network stability and the frequency of lock activities.

Thus, to optimize the battery life, we suggest you check the following:

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 need further assistance, please contact the EZVIZ support team for personalized guidance.
