Are smart locks actually secure, or can they be hacked?

For most homes, physical attack is a far bigger risk than remote hacking. Look for locks with recognised security certifications (for example ANSI/BHMA grades), encrypted Bluetooth/Wi‑Fi, anti-peep keypad features, and tamper or forced-entry alerts. Use a strong, unique app password and enable two-factor authentication if offered. Realistically, a determined intruder is more likely to target a window or the door itself than to hack the lock — so the deadbolt’s physical strength and your door/frame still matter most. A reputable brand with regular firmware updates is the safer bet.
