Passive Electronic-key Lock System Component
The passive electronic locking system is built around four core components: locks, electronic keys, a mobile app, and PC software — working together for controlled access and lock management.
Lock
We offer a wide range of passive electronic lock types, including cam locks, cabinet locks, padlocks, lock cylinders, and glass display cabinet locks — designed to fit different application needs.
APP
Before the electronic key can unlock the lock, authorization must be completed through the mobile app. The app is also used for permission management and operational support.
Electronic Key
The electronic key provides temporary power to the lock, performs authentication, and executes unlocking or locking actions. It also supports operator verification by fingerprint or password, and works with the app and PC software for permission and record management.
PC Software
The PC software serves as the central management platform for configuring permissions, managing users and keys, viewing unlocking records, and organizing lock access across projects or sites.
How Passive Electronic-key Lock System Works
Built on battery-free lock hardware, this system uses an electronic key as the authorization carrier and power source (key-powered + lock-passive hybrid). Combined with App/PC software and a cloud or on-prem database, it delivers secure, intelligent, and low-maintenance access management.
