I have a Nuki this one still works with a normal key, since you install it on top of your existing double cylinder with an emergency function. The Nuki just turns the key or thumb turn of the cylinder. Also means you can’t see from the outside that a smart lock is installed. Battery is not a problem since they last for about 5 months. And you get a warning when it reaches 20%.
