Austrian smart locks that retrofit existing door cylinders for keyless smartphone access
Smart lock from Austria that retrofits onto your existing door cylinder, so you unlock with your phone while the old key keeps working.
Nuki Home Solutions is an Austrian smart-lock manufacturer that retrofits existing door cylinders with a connected motor, turning any standard European door lock into a smartphone-controlled one. Founded by Martin and Jürgen Pansy, the company manufactures in Europe and designs for privacy-conscious homes and short-term rental hosts who want keyless access without changing the door.
The current range includes three smart locks, Smart Lock Pro (flagship with WiFi and Matter over Thread), Smart Lock Go (entry-level) and Smart Lock Ultra (smallest form factor), plus accessories like keypads, door sensors, and an intercom opener that buzzes guests in remotely. Integrations cover Apple HomeKit, Google Home, and Amazon Alexa. Users can share time-restricted digital keys with family, cleaners, or Airbnb guests, and all access is logged.
Against August or Yale, Nuki's pitch is European manufacturing, tool-free retrofit installation (no locksmith, no door modification), and a well-rated mobile app (4.5/5). The Nuki Club offers free shipping, discounts, and flexible payment. It's a natural fit for Europe's predominantly Euro-profile cylinder locks, which most US-centric smart locks don't support.
