Gadronics Brisant has unveiled the Ultion Nuki 2025, its latest high-security smart lock that blends the company’s trusted mechanical engineering with modern smart-home convenience, now with Matter support built in.
It’s the newest evolution of Brisant’s long-running Ultion lineup and one of the most streamlined, design-forward versions yet.
At the core of the new model is Ultion’s 3 Star PLUS lock, a cylinder engineered for serious protection. It includes anti-pick, anti-bump, and anti-drill defenses, plus a molybdenum core that’s 25% denser than iron and highly resistant to corrosion and extreme heat. Paired with precision-cut keys that are significantly thicker than typical designs, the lock meets police-recommended security standards, carries approval from the Master Locksmiths Association, and is backed by Ultion’s £5,000 guarantee.
Brisant has also freshened the design for 2025. The exterior handle comes in seven colour options with a 20-year anti-corrosion guarantee, while the internal handle is offered in black, white, or a polished chrome finish. It’s slimmer and more modern overall, making it easier to match with different door styles.
On the smart side, the Ultion Nuki 2025 finally shifts to built-in Wi-Fi, so there’s no need for bridges or extra hardware. You can lock or unlock the door remotely through the Nuki app, or let the lock handle things automatically. Its proximity-based auto-unlock feature opens the door as you approach and secures it again moments later – useful when your hands are full or you’re juggling pets, kids, or shopping bags.
You still get multiple ways to unlock: a traditional key, the Ultion fob, the wireless keypad, or your smartphone. Inside the home, a central button or twist dial offers simple manual control. The updated motor is faster and quieter, and the rechargeable battery lasts up to nine months before needing a quick top-up via USB-C.
Matter compatibility – specifically Matter over Thread – is one of the biggest upgrades. It ensures smooth integration with Apple Home, Google Home, Alexa, and SmartThings, giving the Ultion Nuki 2025 a level of platform flexibility that older locks lacked.
Despite the engineering overhaul, installation is simple. The unit fits common handle sizes and can be set up in under four minutes with no drilling or wiring required, making it an easy upgrade for homeowners or installers.
The Ultion Nuki 2025 is available now through Ultion’s website.
