Ok, thanks for the information. Reading reviews, it seems these things are always overlooked by the reviewer, or simply not mentioned.
I was considering a Switchbot Lock as an alternative to the Danalock, but then I came across information from a store (not a review) where it said that if the thumb turn on the inside of the door does not rotate with the key, the Switchbot will fall out of alignment and will need to be recalibrated every time the door is locked or unlocked using a key. As my lock works that way, it was very close that I wasted my money on this smart lock if I had not come across this very important piece of information, which I have not seen mentioned anywhere else.
