Nuki Smart LockUltra (5th Gen)

Nuki Smart Lock Ultra (5th Gen) — Premium retrofit smart lock with built-in Wi-Fi and Thread for direct remote access and fast smart home integration.

The Nuki Smart Lock Ultra (5th Gen) is the top-tier model in the Nuki Smart Lock range. Like all Nuki locks it retrofits over your existing euro-profile cylinder, but the Ultra adds built-in Wi-Fi and Thread connectivity — no separate Bridge required for remote access. Control and monitor the lock from anywhere via the Nuki app on iOS or Android. Works with Apple HomeKit (Thread), Amazon Alexa, and Google Assistant natively. Auto Unlock uses geofencing to unlock as you approach; the access log records all events. Time-limited access codes allow keyless guest entry. Suited to homeowners and small businesses who want direct remote control without additional hardware.
