NUKI Smart Lock ULTRA EU (without cylinder)

Maximum performance in the smallest Nuki Smart Lock - Maximum compatibility for Swiss doors

The Nuki Smart Lock Ultra EU is a powerful retrofit solution. It combines maximum locking speed, high security standards and an uncomplicated smart home connection in a compact design.

Important: The Nuki Smart Lock Ultra without cylinder is aimed at customers who already use a Nuki Ultra system. It is ideal for users who want to equip several doors with the same locking system, especially if they already have an Ultra with a matching cylinder and security card and have ordered additional, keyed alike cylinders from the manufacturer. In any case, a compatible Nuki universal cylinder must be used - any standard cylinder is not compatible with the Nuki Smart Lock Ultra.

Outstanding speed
Thanks to the new motor technology, the Smart Lock Ultra is up to three times faster than previous generations. The brushless motor not only ensures higher speed, but also greater efficiency and durability. The Smart Lock Ultra offers three locking modes:
- Insane: Door unlocks in <1.5 seconds
- Standard: Door unlocks in approx. 2 seconds
- Gentle: Reduced volume with slower locking process

Simple installation
The cylinder and Smart Lock can be installed in around 15 minutes - without drilling and without any prior technical knowledge. The step-by-step instructions in the Nuki app support simple self-installation.

Elegant and compact design
Modern look that remains true to the classic Nuki look despite its reduced size: The Smart Lock Ultra combines a compact design with an elegant stainless steel look. Thanks to interchangeable base rings in black and white, the design can be flexibly adapted to different doors and living styles.

Intuitive rechargeable battery solution
The integrated rechargeable battery offers a runtime of several months. Charging is particularly convenient thanks to the magnetic USB-C charging cable: the Smart Lock is fully charged in less than 2 hours - either directly on the door or disassembled.

Smart home integration
The integrated Wi-Fi module enables remote access and control while travelling. Thanks to Matter and Thread support, Nuki can be quickly and seamlessly integrated into all major smart home systems (Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Home Assistant).

Flexible access control and app functions
The Nuki app turns your smartphone into a key. Up to 200 individual access authorisations can be assigned. Smart functions such as Auto Unlock (automatic door opening) and night mode simplify everyday life.
