The All New Ultion Nuki 2025
We're stocking the Ultion Nuki 2025, the newest and most advanced version of Ultion's award-winning smart lock—designed specifically to give homeowners like you unbeatable security, effortless convenience, and a beautiful upgrade to your front UPVC door security. We are experts in this field with 10 year's experience, and we have never used a better UK smart lock!
Unmatched Security for Your Peace of Mind
At the heart of the Ultion Nuki 2025 is the Insurance Approved Ultion 3 Star PLUS core—one of the toughest locks ever made. It delivers top-tier protection with anti-pick, anti-bump, and anti-drill features to help keep burglars out.
The core features a molybdenum shield that's 25% denser than iron, offering exceptional strength, ductility, corrosion resistance, and one of the highest melting points of any pure element. Paired with precision-cut keys that are 60% thicker than standard options, it resists snapping and bending far better than most. It's Police Preferred, approved by the Master Locksmiths Association, and comes with a £5,000 burglary guarantee—a promise that has never had to pay out on.
A Sleek, Modern Look That Enhances Your Home
Say goodbye to bulky smart locks. The Ultion Nuki 2025 boasts an ultra-sleek, streamlined design that's one of the most attractive options available. Customize the external handle with seven stunning colors and various fixing sizes to perfectly match your home's style. Every external handle includes a 20-year anti-corrosion guarantee.
Inside, choose from black, white, or a fresh chrome finish for the handle—ensuring it blends seamlessly and elevates the look of your entrance.
Smart Features That Make Life Easier
With built-in Wi-Fi, there's no extra hub or bridge needed—just connect directly to your home network for simple setup. Use the Nuki app to lock or unlock your door from anywhere, at any time, with a quick tap on your phone.
Love hands-free convenience? Enable auto-unlock so the door opens as you approach (using your phone's proximity), then locks automatically a few seconds after you enter. You can toggle this feature on or off and tweak all settings to suit your routine.
You still have full flexibility: use your existing key, add a convenient Ultion key fob, install a wireless keypad, or rely on your smartphone—or combine them all. Inside, a simple press of the central button locks or unlocks the door, or twist the dial for manual control.
Key Features You'll Love:
- Built-in Wi-Fi — Remote access and over-the-air updates straight through the Nuki app—no extra devices required.
- Faster, Quieter Motor — Smoother, quicker locking and unlocking for a premium everyday experience.
- Matter Compatibility — Works seamlessly with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and more via Matter over Thread.

What happens if there is a power cut, or my Wi-Fi goes down? ▼
You’re never locked out (or in) with Ultion Nuki. Being Bluetooth and battery powered you can still control the door whilst at home using your phone, wireless keypad, wireless fob or even your key. Only remote connections that rely on the internet and power will be affected.
How long do the batteries last and what happens when they run out? ▼

When the battery level reaches below 20% you will be notified via the Nuki app and directly on the Smart Lock via the LED lights. You can also enable email notifications.

Are there any ongoing charges? ▼
Absolutely none. There isn’t even a charge for sending additional electronic keys.
Will it fit my door? ▼
By using the same fixing holes already in your door, replacing your door handle with Ultion Nuki is simple. As well as an escutcheon model (the type of door that doesn’t have a push down handle) it will easily replace all common UK push down door handles. It accommodates lever handles where the distance between the handle fixings is 215mm, 211mm and 122mm. The distance between the centre of the handle (spindle) and the barrel (keyhole) should be 92mm.

How does auto lock work? ▼
The auto-lock function is set on a timer from the app. The timer starts whenever the door is unlocked, and it will automatically lock itself again once the timer expires.
The Ultion Nuki also features a Night Mode. Just set the time it should start at night and the time it should end in the morning. It will automatically lock at the start of Night Mode and enable energy saving mode until the morning.
Auto lock can also be set to only work during Night Mode if you need to keep the door unlocked during the day, if you’re a business owner for example. You can even set schedules to lock and unlock at certain times.
How does auto unlock work? ▼
Auto Unlock works by combining GPS, Bluetooth and geofences (iBeacons). With the GPS on your smartphone Nuki recognizes when you leave your home. When you approach your home again and enter a geofence near the smart lock, the app Bluetooth scans for your smart lock. If the app establishes a Bluetooth connection within 20 minutes of entering the geofence your door will automatically unlock. To avoid unwanted locking operations the next Auto Unlock will only be triggered when you exit the geofence and enter it again.
Can the lock be operated manually? ▼
The Ultion Nuki can always be operated manually through the use of a physical high-security key or the manual thumbturn.

What’s to stop someone shouting ‘Alexa, unlock my door’ through the letterbox? ▼
