Am I missing something or this is a bit dangerous ?

Most recent lock (at least in Geneva) doesn't allow 2 keys to be inserted at the same time.
So, if for any reason, Nuki is stuck, I did not replace the battery in time (I know it warn me), or any other hardware issue. How can I enter my house ?
My spare key won't open the door since there is already 1 key in the cylinder, and if I have to call someone to break the door, since they are the new fireproof door, it's gonna cost me X'000CHF.

Accepted Answer

No, that's correct.
You can buy/install a new cylinder with so called priority access (allows both keys to turn at the same time with external key priority).

Answer

Same situation with the one-way cylinder and I forgot my phone in on the first day of having it installed, before having a keypad... Trust me having it immediately registered to Nuki Web saved my life.
