Nuki KeyPad 2.0 Review - An Essential Upgrade? I have been using the Nuki Smart Lock 3.0 with the optional Keypad 1.0 for some time – I wouldn’t want to live without it. While the rival SwitchBot keypad had the fingerprint option, the more expensive Nuki system did not – but that has now been corrected with the arrival of the Nuki Keypad 2.0.
