Nuki Smart Lock Ultra Review: The Premium, Best-of-Nuki Smart Lock
Nuki's most refined lock yet, faster, more compact and higher quality, with built-in Wi-Fi and Matter, at a top-tier price.
The Nuki Smart Lock Ultra is the flagship of Nuki's lineup and, by most owner accounts, the brand's best lock so far: noticeably faster, more compact and more premium than previous generations, with built-in Wi-Fi and Matter (over Thread) so remote and smart-home access work without add-ons. It installs in about an hour with a guided app and included tools, and offers hands-free auto-unlock. The main caveat is the high price, with only minor install quirks otherwise.

Who is the Nuki Smart Lock Ultra for?
This is the top-tier model in Nuki's range, for people who want the most refined version and will pay for it. Like the rest of the line it is a smart lock for European-style doors, but the Ultra is the most compact and premium, with built-in Wi-Fi, Bluetooth and Matter (over Thread), three lock modes, a rechargeable built-in battery, and full support for Apple HomeKit, Google Home, Alexa, SmartThings and Home Assistant. It offers auto-lock after the door closes and geolocation hands-free auto-unlock. Keypad and fingerprint entry are separate accessories. It best suits smart-home enthusiasts and Apple households who want Nuki's fastest, best-built lock and seamless Matter-over-Thread setup.
What buyers love
Owners, including several long-time Nuki users, consistently call the Ultra a real upgrade: faster response, a more premium feel and more comfortable operation than older models, with one calling it the best Nuki version yet. The unboxing and app give an Apple-like impression, and despite looking complex at first, installation is described as simple and quick (around an hour or less) thanks to a step-by-step animated in-app guide and included tools, scan the QR code and it is added to Apple Home via Matter over Thread. Built-in Wi-Fi means remote access works out of the box, the build quality and design are praised highly, it adapts to most door thicknesses (UK/US/EU standards), and Nuki's customer support again earns strong marks.
What to know before you buy
The biggest consideration is price: it is the most expensive Nuki and a premium product overall, though owners broadly feel it is worth it. Install quirks are minor: setting the cylinder length can be slightly tricky, and one owner traced intermittent locking errors to an included screw being too short, easily fixed by swapping in a slightly longer hardware-store screw. Like the rest of the range it is a retrofit for European-style cylinders (not US deadbolts), is not weather-resistant, and has no built-in keypad/fingerprint/NFC/Apple Home Key (the keypad is a separate accessory). It uses a rechargeable battery rated around six months. Overall, complaints are few and mostly about cost.
Is the Nuki Smart Lock Ultra worth it?
For buyers who want the best Nuki and a polished, fast, Matter-ready smart lock, yes, it earns the highest average rating in the Nuki line, and owners repeatedly say it justifies its premium with superior speed, build and refinement. Built-in Wi-Fi and easy Matter-over-Thread setup make it especially appealing for Apple Home users. Just budget for the top-tier price (more with the keypad), confirm your door/cylinder fit, and accept it is a European retrofit. If you want the flagship experience, it is an excellent choice.
Frequently asked questions
Why choose the Ultra over the Nuki Pro or Go?
The Ultra is the flagship: the most compact and premium, with the fastest response and best build. Like the Pro it has built-in Wi-Fi and a rechargeable battery (so no paid add-ons for remote access), but owners describe it as a noticeable step up in speed and refinement over both the Pro and the Go.
Does it need a separate bridge for remote access?
No. It has built-in Wi-Fi, so remote control and smart-home integration work out of the box without buying a bridge or unlock add-on.
Is it hard to install?
No. Despite looking complex when unboxed, the in-app guided setup with animated steps and the included tools make installation quick (around an hour or less). Setting the cylinder length is the only slightly fiddly part.
Which platforms does it support?
Apple HomeKit, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, plus Matter over Thread. You can add it to Apple Home by scanning the QR code.
Does it have a keypad or fingerprint reader?
Not built in. Passcode and fingerprint entry use Nuki's separate Keypad accessory. On its own it uses Bluetooth, hands-free auto-unlock, the app and your physical key.
