smartlock

A smartlock is an electromechanical lock that can be controlled and monitored remotely using a smartphone app or a connected home system. It typically replaces or works with an existing door lock such as a deadbolt or latch and uses an electronic actuator to extend or retract the bolt.

Most devices are battery powered and include a mechanical key override. They connect via Bluetooth, Wi-Fi, Z-Wave, or Zigbee, and sometimes via Thread or a hub. Access can be granted through mobile apps, PIN codes, biometric credentials, or key fobs. Many models support remote locking and unlocking, hands-free operations via geofencing, temporary access codes for visitors, and audit trails showing who unlocked the door and when.

Installation varies by model and door type; cylindrical, deadbolt, or mortise configurations may require different hardware. Some locks are single‑cylinder with exterior electronics and a separate interior plate; others replace the internal mechanism entirely. Battery life is commonly several months to a year, depending on usage; some offer low-battery alerts and backup power options.

Security considerations: smartlocks expand the attack surface; risks include weak passwords, compromised cloud accounts, or outdated firmware. Mitigate with strong authentication, regular firmware updates, encryption, disabling remote exposure if not needed, and using a reputable brand. Use a mechanical key as a backup. Privacy concerns include access logs and data sharing with manufacturers.

Standards and interoperability: many locks use Bluetooth, Wi‑Fi, Z‑Wave, or Zigbee; compatibility with home automation ecosystems and voice assistants varies. Some devices support Matter, enabling interoperability across platforms, but support is not universal. A hub or bridge may be required for remote access or certain protocols.
