Nuki Unveils Smart Lock Ultra With Faster Operation, Compact Design

Austrian smart lock maker Nuki has announced its new Smart Lock Ultra, featuring a smaller design and claiming significantly faster operation than its predecessor.

The Smart Lock Ultra is one-third the size of previous Nuki models. This has been achieved through a new built-in battery design that eliminates the need for a bulky battery compartment, according to the company. The lock features a new brushless motor, similar to those used in electric vehicles, enabling it to unlock in under 1.5 seconds, which could make it one of the fastest smart locks available.

Built-in Wi-Fi eliminates the need for a separate bridge, while Matter-over-Thread and Bluetooth connectivity options are also included. The lock supports all major smart home platforms including Apple Home, Amazon Alexa, and Google Home. Battery life is rated at six months per charge, with charging handled via an included two-meter magnetic cable.

The European version requires replacing the entire lock cylinder and comes with three physical keys, while an upcoming US model will work as a retrofit solution similar to August smart locks. The lock can be controlled through multiple methods, including geofencing, via the smartphone app, or compatible smart home platforms, and it works with Nuki's existing accessories like key fobs and keypads.

The fifth-generation Nuki Smart Lock Ultra will be available in Europe this December for €349, with the US version planned for the second quarter of 2025.

I dont trust smart locks. Ever since my buddies beach house said his house was unlocked after I left I lost all trust in them.

The house was absolutely locked. The lock makes two noises, after the first noise I jiggled the handle, it was locked. I then straightened the welcome mat in front of his door while waiting for the second noise, then the second noise happened and I jiggled the handle again. It was locked. ZERO doubt in my mind. Doors being locked are one thing I'm hyper focused about.

Next day I get a text telling me I didn't lock the beach house. The locks app was either reporting the wrong status, or something is screwy with the lock.

Yes, this product went all the way through it's development cycle without anyone thinking of something that you thought of in the few seconds it took you to not read the article.
I want to have smart locks, but our keys still work after decades in the same locks. Never recharged the keys.

Charging a smart lock while still attached to the door seems … suboptimal to me.

Hopefully the new motor will make it into the „traditional“ design!
