Hi there,
I am by far no expert in doors and door locks. We are finishing our new house and organizing the door - I have told the manufacturer we need a Euro Cylinder lock with an Emergency function. They have gotten back to me and said:
“I have been making some calls on this one and with the 60mm backset you can leave the key inside and open from the outside with the smartlock, but if you want to open from the outside with a key (while the key is still in position inside) you would need a 70mm backset. However, not sure that works with the Nuki system.”
Can someone answer this for me?
