I don't own the new chime or chime pro, but I do have an echo dot in my garage. I mostly have it for playing music out there when working in the garage and/or cars, but I have not had any issues with someone trying to access it via voice. It's on the far wall away from the garage door on top of a cabinet, and they'd have to scream at the top of their lungs to get it to do anything they wanted it to do with the door closed.
