Smart locks are tech-integrated devices that replace traditional key-only locks with multiple unlocking methods (biometrics, APP, etc.). They offer security features (alarms, anti-interference), smart management (remote control), and emergency backups. Used in homes, rentals, offices, and hospitals, their main role is to boost access safety, convenience, and efficiency—making them essential for smart living.
