Question about Nuki Smart Lock 2.0 CH

can you still unlock with the regular key or exclusively via the "digital" way?

Nuki customer service answers: "you can also order the adapters separately:

But you first have to make sure that your Smart Lock can work with the adapters (you can see on the back of the Smart Lock: those for knob cylinders have two recesses on the left and right side in addition to the key slot)".

Does this product have this feature?

Unfortunately, we do not have any further information on this yet, but as soon as we know more, we will be happy to adjust this here.
