älylukitus

älylukitus, or smart lock, is an electronic locking device that replaces or augments traditional mechanical door locks to control access using digital interfaces. It typically combines a motorized bolt or latch with electronics and a wireless communication module, enabling door operation without a physical key.

Most älylukitus systems are powered by batteries and include components such as a microcontroller, a motorized actuator, and a wireless radio (Bluetooth, Wi‑Fi, Zigbee, or Z‑Wave). Access is granted through a smartphone app, a keypad code, NFC or RFID key fobs, or biometrics; many models support remote operation via a cloud service or local hub and can be integrated into smart home ecosystems.

Functions include auto-lock after a timeout, temporary or scheduled access for guests, activity logging, notifications, and audit trails. Some locks support mechanical backup keys or powered emergency release for power failures, and can operate in offline mode if necessary.

Installation ranges from retrofit kits that replace the cylinder or latch to full hardware replacements. Compatibility depends on door and existing lock dimensions, as well as the availability of a suitable power supply. Professional installation is common; many models offer installation guides for DIY setups.

Security and privacy considerations are important. Smart locks can be vulnerable to hacking, relay attacks, or cloud service breaches if not properly secured. Strong encryption, secure pairing, regular firmware updates, and careful access control reduce risk. Power failure may temporarily disable the lock, making a mechanical backup key or external power source desirable.
