Your electronic door lock for secure and affordable keyless access


The Nuki Smart Lock 4.0 turns your smartphone into a smart key. The electronic lock installs in a few minutes on the inside of your door, on the existing cylinder, and is invisible from the outside. With the free app (iOS/Android), you can open your door without a key.

The Nuki App also allows you to create up to 200 permanent, temporary, or recurring virtual keys. This way, your family and friends, the dog sitter, and maintenance personnel can enter precisely when you want them to.

State-of-the-art encryption mechanisms meet the highest security standards. If necessary, your Nuki Smart Lock can be removed without a trace, making it perfectly suited for rental properties.

Nuki Smart Lock compatible with Matter

Whether it's smart assistants, intelligent doorbells, or home automation hubs, Nuki can integrate into many common home automation systems. Nuki uses Matter via Thread. This new technology has been specially developed for home automation applications. Thread provides a robust and fast network with a wide range.
