How to Factory Reset the Lock
The Lock set consists of 2 parts: The TX Dongle, and the RX Dongle. While each part needs to be resetted indepedently, the way to do them are exactly the same.
Step 1: Power ON the dongle that you'd like to reset.
Step 2: Get the dongle into BLUETOOTH PAIRING MODE.
Press & Hold the Multi-Function Button on the dongle you'd like to reset for about 5 seconds until the LED indicator starts flashing RED & BLUE.
Step 3: Factory Reset.
Double-Click the same button, you'll see the LED indicator turn PINK. The dongle will then enter pairing mode again (flashing RED & BLUE,) indicating a successful reset.
Keep both dongles close to each other, and they'll reconnect with each other right away.
