Hello, I ordered the same lock and had to order a suitable adapter for Keso round knob cylinders via Etsy, as SmartLock Pro was obviously only built for the key versions and Nuki.io does not provide any adapters for this case

The access control system is compatible with most European cylinders, but in some cases adapters may be required. Specifically for a KESO lock with a round knob, it is not explicitly stated whether an adapter is required or whether compatibility is direct. Installation may therefore be possible, but an adapter may be required depending on the exact model of KESO lock.

Hello I bought a nuki smart lock 5 ultra I can not install on my lock keso it round, if you find a solution how to install my nuki smart lock 5 ultra on a lock keso thank you for your help ????
