With the latest Smart Lock generation 2025, Nuki is launching three new models: the affordable Nuki Go , the powerful Nuki Smart Lock Pro (5th generation) , and the new premium model Nuki Ultra . All three support the future-proof smart home standard Matter over Thread . But which lock is right for you?
Matter over Thread – the future of the smart home
Thread is a low-power wireless protocol that's significantly more stable and responsive than Wi-Fi. Combined with the cross-manufacturer standard Matter , it ensures your devices communicate directly, locally, and without the cloud—regardless of whether you use Apple Home, Google Home, or Alexa.
All three Nuki models of the 2025 generation are "Matter-ready" – with a focus on maximum compatibility and future-proofing. The other advantages Matter brings to you and your home are summarized here: Matter Advantages.

Which Nuki lock suits your smart home?
Nuki Go – the affordable entry-level option
With the Nuki Go, you get an affordable door lock with Matter and Thread support. Wi-Fi isn't integrated—for remote access, you'll need a Nuki Bridge or a Matter Controller with a Thread Border Router. The knob is made of plastic, and the lock is powered by AA batteries—ideal for those who want simplicity and affordability.
Nuki Smart Lock Pro (5th generation) – the powerful mid-range model
The 5th generation Nuki Pro is technically almost identical to the Ultra, except it lacks the integrated locking cylinder and has a slightly longer knob. Ideal for anyone looking for a fully-fledged smart lock with the latest technology and where space isn't an issue. It's significantly quieter in operation than the Go thanks to a brushless motor.
Nuki Ultra – the premium smart lock with everything
The Nuki Smart Lock Ultra is technically almost identical to the Pro, but includes a variable locking cylinder and a slightly shorter knob. It's ideal for anyone looking for a fully-fledged smart lock with the latest technology in the smallest possible space. It's significantly quieter in operation than the Go thanks to a brushless motor.
Thread or Wi-Fi? When do you need what?
If you already have a Thread Border Router at home (Apple HomePod mini, Nest Hub 2nd Gen, etc.), you can rely directly on Matter – local, fast, and cloud-free. This saves energy and increases security.
Here you can find a selection of Matter controllers.
