Mechanical locks  adopt pure physical mechanical structures without electronic components or power supply support. They rely on mechanical matching between keys and lock cylinders to complete locking and unlocking actions. With a simple and mature structure, mechanical locks feature high stability, zero power consumption, strong environmental adaptability, and extremely low failure rates in extreme temperature, humidity and long-term static use. They require no maintenance, support long service life, and are highly compatible with various door bodies and engineering standards. As traditional and reliable security hardware, mechanical locks are widely used in mass engineering projects, public facilities, and cost-sensitive bulk procurement scenarios. Their main limitations are fixed access authority, manual key management, and risks of key loss, duplication and difficult permission recycling.

Smart locks   integrate electronic modules, intelligent control systems and mechanical structures, supporting diversified unlocking methods such as passwords, IC cards, Bluetooth and mobile APP access. Different from manual key operation, smart locks realize programmable access management, dynamic permission adjustment and remote operation. They record accurate unlocking logs, support multi-user hierarchical management, and greatly improve the convenience and intelligence of space security management. Suitable for high-end residences, serviced apartments, office buildings, hotel projects and intelligent community supporting scenarios, smart locks solve the pain points of difficult key distribution and inconvenient authority update. The objective drawbacks include regular power supply maintenance, higher unit cost, and certain environmental requirements for electronic components.
