When smart locks first appeared, many people thought they would be easy to hack and cause serious security and privacy problems. Now that smart locks are widely used, we don’t really see news about major incidents. In fact, real-world use seems to show the opposite: properly designed smart locks can be safer than traditional locks or basic cameras without smart access

That’s right, I was also afraid it would be so buggy and easy to hack.
But now seeing how it works and having one of the locks myself, I say - bull. Any respectable smart lock manufacturer will have proper cryptography.
And even if it was hackable, then most of the time it’s easier to just break into a house by just breaking a window, stealing the keys, lockpick or just break the eurolock cylinder with pliers. Or just check if the door is open. Most common crimes are crimes of opportunity anyway.
So why waste so many time sitting next to the lock, trying to hack it for hours, probably alerting the neighbors? The smart lock is not the weakest link. I just don’t worry anymore

Hello @i4071505
Aqara smart locks are among the best and most innovative for a smart home, and their security is excellent. I use several of them, and my favorite is the D200i, as I have a steel door.

The thing that convinced me that Aqara really cares about security is that you cannot buy the pinpad separately for the U200 (unlike some other brands). The fact that there is no way to buy or pair a new keypad suggests there is no software pairing that could be exploited. And the lock probably uses some kind of hardware keys built into the keypad and the lock mechanism so it cannot be hacked.
People are irritated they cannot buy a replacement keypad, and I’m glad I cannot

Yeah, I’ve had two break-ins during my 30+ years living in this house. Both were before any kind of smart devices, but neither bothered with trying to manipulate a mechanical lock. (Which is relatively easy to do using a bump key in most cases.) Both were brute-force entries. I would expect that to remain true now.
