Buying Guide
What access methods do you need? Choose locks offering fingerprint, keypad, RFID, and app control if you value high flexibility and quick access for multiple users.
Is electricity available? Smart locks require power and sometimes a stable 2.4 GHz Wi-Fi network. Mechanical options work without batteries or network dependence.
Door compatibility matters. Check door thickness (commonly 13/16″ to 4-3/4″ or 30–120 mm) and whether the mortise or surface mount fits your frame.
Security features. Look for auto-relock, tamper alarms, wrong-entry limits, and encryption to protect against tampering and unauthorized access.
Installation considerations. Some locks require drilling or specific spindle lengths. Confirm whether the handle orientation is reversible for your door swing.
Maintenance and power. Battery-powered units need battery life planning; mechanical units should be checked for latch compatibility and wear.
