Updating the firmware for your Lockly lock is easy.  You will need to be within Bluetooth range of the lock and connected via Bluetooth.  You will then go into your Lockly app, select the lock that you would like to update, go to Settings in the lower right of the screen and at the bottom will be the option for Firmware Update.  Simply go through the steps of downloading and installing that Firmware from there.  It should only take about 5-7 minutes.
