I said could, it is possible Huge companies have been hacked so this is a Smart Lock. Anyone could just exploit a flaw which could be found at any time.
Where’s the proof?
Would not get this. Someone could hack it and get in.
Yes but that is not an alternative as it isn't compatible with a multi lever system.
I'm using PINEWORLD fingerprint smart lock. Cheaper than this and you'll get FP/Keypard/smart key unlock options.
