The mobile application interacts with a dedicated panel on which any physical key, such as a car key or shutter switch, can be mounted. This panel converts the physical key into a smart key, providing digital functionality. Once connected to the app, users can manage their smart keys via their mobile phone, allowing them to lock or unlock the vehicle, control the shutters, and set remote access permissions. This system enhances security by eliminating the need for traditional keys and providing real-time control, all within an easy-to-use application interface. Whether you're at home, in the car, or on the go, the app provides a seamless experience for users to easily control and monitor their access.
