An electronic lock doesn't have to be impenetrable, just take more than 5 minutes to break into. This is about as long as a determined thief might spend picking/breaking your regular lock before they're in or they move on to the next target. If you add a bit of obscurity in the mix you could be just as safe. A smartlock that looks like a regular lock, or has all the "smart components" on the inside of the door (like smart bolt-on key turners) would not stand out.
