I've been using these: https://www.amazon.com/Schlage-BE365...less+deadbolts
However, as the kids get older I don't want them to be able to give out the code (like one of my siblings did with the house key, and more than once ).
So I'm trying to find a fingerprint controlled lock, but not having much luck figuring out what is a good option.
I'm leery of the phone controlled options, as I worry about someone stealing a phone, and gaining access, or hacking the signal. However, I'm open to info that shows those systems have improved.
I like the keypad Schlage I'm currently using, because I don't have to worry about key control, and you throw/retract the bolt with a manual lever, not an electric motor. Again, the flaw is a teenager giving the code to a friend/boyfriend/girlfriend.
Thanks in advance for any help.
