They also point out they can use this to bypass security and open "smart-locks".. this is slightly more concerning than just buying hand sanitizer.. I wouldn't be caught dead with one of these smart-lock devices, but I have friends who aren't so cautious.

I have owned several smart locks and every single one has required a secret passcode to actually unlock via a smart assistant. Working backwards, the real threat if they didn't do that is just someone shouting through the window.

I forget if it was this article or not but someone mentioned that a few of the smart locks that do have secret codes don't rate limit them, so, in theory, they could brute force a pin code or password.

I guess the idea is that they think nobody is going to sit there and shout pin codes until it unlocks?

I own a smart lock and my Google home device will only lock the door. You can't ask Google to unlock it.
