How do I check the firmware version of a smart door lock?

Last Updated on：2024-08-06 06:09:06

If a smart door lock has a screen, view the firmware version directly from the screen. If a smart door lock does not have a screen, use one of the following methods based on the lock brand and model:

For a FingerCrystal smart door lock, press 0 and the pound key (#). The numeric keyboard flashes and displays the version number. (''*'' represents ''.'')
For a ZmartPlus DS04/05/08 smart door lock, press *# and enter the administrator password to enter the administrator mode. Check the firmware version based on the voice prompt and record the version number.
Tap the smart door lock in the device list of the App to open the device's control panel. Tap the button in the upper right corner to enter the device editing page. Tap Check for Firmware Update to view the firmware version.
