Keypad 2 NFC featuring Tap to Unlock

Did you know about our newest Keypad 2 with Tap to Unlock? Simply tap your smartphone or smartwatch on the Keypad to unlock your door. If you have an Apple or Samsung setup with a Matter-capable Hub, this also works with Samsung Digital Keys or Apple Home Keys.

A person unlocks their door via the Keypad 2 NFC. They tap their smartphone on the Keypad.

Tap to Unlock: As simple as Tap to Pay

Tap to Unlock is very easy to use. Simply tap your phone on the Keypad 2 NFC and unlock your door. It's similar to Tap to Pay via NFC.

Smart Home Mode or Nuki App Mode

Depending on your setup, you can use two modes for Tap to Unlock: The Smart Home Mode or the Nuki App Mode. 
For the Smart Home Mode you need a Samsung or Apple setup with a Matter-capable hub. In express mode, you then do not even have to unlock your phone to use Tap to Unlock. 
The Nuki App Mode needs no additional equipment. However, you need to unlock your phone to use Tap to Unlock. 
For further information, see this comparison of the two Tap to Unlock modes.

Minor changes and improvements in the background ensure that the Keypad runs even more smoothly.

Enjoy using your Keypad with the improved firmware.
