Getting Started

01

Pair over Bluetooth

Turn the key on and connect it in your system's Bluetooth settings, the same way you would a wireless keyboard.

02

Pair in the app

Open the app and pair again there. This is a separate, encrypted pairing step: confirm it by pressing the button on the underside of the device.

03

Enroll a fingerprint

Touch the sensor about 12 times, lifting and tilting slightly each time.
