Can smart locks be hacked?

Theoretically possible but extremely rare. Bluetooth and Wi-Fi locks use AES-256 encryption. Physical bypass (picking) is a more realistic threat than digital hacking. ANSI Grade 1 locks resist physical attacks best.

What happens when the battery dies?

Most smart locks alert you weeks before battery death. If the battery dies, you can use your physical key (August, Schlage) or touch a 9V battery to the exterior terminals for emergency power (most brands).
