I have read many articles about the hacking of smartlocks, and there is no question, most have weaknesses in this was. But if you believe the person breaking into your house is going to do it by hacking your lock, it shows you don't know much about crime today. Almost all other non-smartlocks have weaknesses as well. So the fact is, no lock is going to stop someone from getting into your house if they want to. A lock is just one layer of security, and probably not even the strongest one.
Get a lock that is easy for you to use. If someone is going to break in your door, the lock doesn't matter much.
