Nuki Smart Lock Ultra

Start by changing your existing lock cylinder with the premium Universal Cylinder that comes with your Smart Lock Ultra. Then you simply have to mount your new Smart Lock on top of the cylinder. No drill or technical know-how is required. You can follow the step-by-step guide in the app and install your Smart Lock Ultra in 15 minutes.

Nuki uses state-of-the-art encryption mechanisms commonly used in online banking. All communication with the Smart Lock is protected with end-to-end encryption. We also have our Smart Lock regularly inspected and certified by independent security institutes.

Additionally, the Universal Cylinder that comes with your Nuki Ultra offers best-in-class physical security for your door and offers a drill-resistant body. Nuki Universal Cylinder has passed the industry’s highest security mark (SKG***) and has both EN 1303 and DIN18252 certifications.

Nuki Universal Cylinder is a lock cylinder designed specifically for Nuki Smart Locks. The Universal Cylinder replaces the current cylinder installed on your door. A lock cylinder is where you insert your key to lock and unlock your door – that’s why when you change your cylinder, you’ll also receive new keys.

Nuki Ultra is designed to offer a premium experience, both in convenience and quality. The integrated Universal Cylinder offers unmatched security for your door and is reinforced with a drill-resistant body. Additionally, the Universal Cylinder makes it possible to use the Smart Lock Ultra with the vast majority of doors.

Battery life depends heavily on your usage, door type, locking modes, and other factors. In general, you can expect the following ranges for your Smart Lock Ultra’s battery life:

• 7-9 months without remote access
• 5-7 months with remote access over Thread
• 4-6 months with remote access over WiFi

The Universal Cylinder that comes with your Smart Lock Ultra has a so-called “emergency function”. This basically means you can use your physical keys to open your door, even with your Smart Lock Ultra installed on your door. So even if your Smart Lock is out of power, you can simply use your keys to come in.

You’ll always receive a warning when your lock’s battery level drops below 20%, giving you more than enough time to quickly recharge your device.

In case you simply don’t have your phone at hand, there are many other ways to unlock your door too, for example:

• Asking someone with an access permission to open it for you remotely
• Using the Nuki Web service if you have an account to open your door without a phone
• Using a smartwatch to open your door
• Using one of our accessories to open your door with a code, fingerprint, or a Fob.

Nuki Smart Lock Ultra is compatible with a wide range of Nuki accessories, including the Fob, Keypad and Keypad 2, Opener and Door Sensor.

Please note that since Nuki Smart Lock Ultra already includes a built-in Wi-Fi module, it is not compatible with a Nuki Bridge. Similarly, since Nuki Ultra is shipped with a new and improved Universal Cylinder, it is not compatible with older Universal Cylinders.
