Researched a bit into this some time back and I was not convinced.

It would be nice to have a lock I could assign entry codes for different users and still have a physical key as an emergency backup but the obcession with these locks being tied to an app and/or internet discouraged me.

I stayed with purely mechanical locks with complex keys and secondary arms that make the task to break down a door much harder.

Don’t know how it is in other countries but I’ve been to shops where I specifically asked for locks that would give a locksmith a bad time to pick and was shown a few models where the only way to break it was to put a whole cutter to it and cut out the entire drum.
