A smart lock is an advanced electronic locking system that enhances home and commercial security by allowing keyless access via smartphones, PIN codes, biometrics, or remote controls. These locks provide convenience, security, and remote monitoring, making them a vital part of modern smart home ecosystems.

How Smart Locks Work
Smart locks use wireless communication technologies such as Wi-Fi, Bluetooth, Z-Wave, or Zigbee to connect with smartphones and smart home systems. Users can lock and unlock doors remotely, track entry logs, and even integrate them with voice assistants like Alexa, Google Assistant, and Siri.

Key Features of Smart Locks
Keyless Entry: Unlock using PIN codes, fingerprint scans, RFID cards, or mobile apps.

Remote Access: Control and monitor locks from anywhere using Wi-Fi or mobile networks.

Auto-Locking and Unlocking: Some models detect proximity via Bluetooth or geofencing and lock/unlock automatically.

Access Sharing: Grant temporary or permanent digital keys to family members, guests, or service providers.

Tamper Alerts & Activity Logs: Get real-time notifications if unauthorized access is attempted.

Battery Backup & Emergency Access: Many smart locks offer low-battery alerts and mechanical key backups.
