Hands free auto-unlock for freedom of movement
Talking on the phone and holding the dog’s lead? Busy carrying shopping bags? You don’t have to pick up your keys or your phone. Ultion Nuki unlocks the door when it senses you’re close to it, and locks it again after a few seconds. You can turn the feature on and off and customise everything.
The key is the key
We think that to make something truly smart is to not remove what you already had. That’s why Ultion Nuki can still be operated with a key.
Still keeping the bad guys out
It’s smart and gorgeous, but that’s far from enough. Our priority is to keep bad guys out. The heart of the Ultion Nuki is a 3-star PLUS Ultion lock, and the Nuki unit has the highest AV security rating, with three stars.
One size fits all
The Ultion Nuki has been designed to fit existing doors with handle fixings of 215mm, 211mm, 122mm and even doors with an escutcheon lock. Elegance matches discretion. Our all-white internal finish perfectly blends with most doors’ classic white internal paint.
Press, twist and relax
The centre of the Ultion Nuki is a button. This can be set to tell the motor to lock or unlock the door. Or you can simply twist the dial for a manual operation.
Open up a better way of living
with our exclusive accessories
For complete peace of mind, the bridge allows you to lock and unlock the door from anywhere in the world, using our app’s highly secure system.
You can customise your external handle with seven colours and a range of fixing sizes. Our external handles come with a 20-year anti-corrosion guarantee.
The bluetooth key fob can be set to unlock your door within 10 metres of the door after 2 or 3 presses to give you the peace of mind that an accidental press won’t unlock the door.
With our sleek, modern Bluetooth keypad, you can set 100 different passwords and lock the door by pressing one button. You can even have codes that work only at specific times and on particular days. You’ll never need to take your keys with you again.
Rechargeable battery pack
The 4 AA batteries bundled in the Ultion Nuki will keep powering your door lock for over a year, and the app will notfiy you when the batteries are running low. Alternatively there is an optional USB rechargeable battery pack.
Frequently asked Questions

All communication with Ultion Nuki lock is protected with state-of-the-art end-to-end encryption commonly used in online banking.
It is also regularly inspected and certified by independent security institutes. The Nuki Smart Lock achieves the highest AV-TEST available (level 3).
Because there is no drilling or wiring, it takes only minutes to replace your existing handle with an Ultion Nuki. This video shows how easy it is to fit.
Ultion Nuki was designed with this type of door in mind. All Ultion Nuki unlocking features work with your door. When you pass through the door lift the handle as normal and all locking features are available.
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.
The Ultion Nuki uses 4x AA batteries and they will last for several months. 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. Even if you miss these, the Ultion Nuki is also a normal mechanical lock. You can use a key from the outside and the dial on the inside until the batteries are replaced.
The Ultion Nuki is also compatible with rechargeable batteries. For a longer usage we recommend the rechargeable batteries Panasonic eneloop pro. These batteries last about twice as long as alkaline batteries.
Absolutely none. There isn’t even a charge for sending additional electronic keys.
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.
The adjustable design of the Ultion Nuki handle also means that should you change your door, or move house, you can continue to use it on the new door without needing to buy a new handle.
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.
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.
The Ultion Nuki can always be operated manually through the use of a physical high-security key or the manual thumbturn.
The wireless keypad is battery and Bluetooth powered. This means there are no wires and it can be positioned anywhere within Bluetooth range of your door, it doesn’t have to be on the door.
The Ultion Nuki can be integrated with Apple Homekit, Google Home, and Amazon Alexa. This enables you to lock and unlock via voice commands, add the lock to routines, and operate the lock from their respective apps.
The lock can also be connected to many other Smart home systems, such as IFTTT, Ring app, and Homey
Custom smart home systems are also accommodated with an an open API enabling integration of into lots of different use cases.
Please note that Alexa and Google Home integrations required the bridge (sold separately).
You’re still protected if you combine Alexa/ Google Home with Ultion Nuki. During the Alexa/ Google Home setup you will be prompted to set up a passcode. Alexa then asks for the passcode whenever an unlock request is made. The code is not required when you lock the door.
Ultion Nuki works with a specific type of Ultion lock that has only ever been used within an Ultion Smart lock. Whilst Ultion locks that are operated from the inside with a key or a thumbturn will not fit in Ultion Nuki we can make your Ultion Nuki work from your existing Ultion key. There is no charge for this service.
When used with the bridge, Ultion Nuki is a great addition to any Airbnb with seamless integration with the Airbnb app. Your guests automatically receive a digital access code after booking and will automatically expire at the end of their stay.
