Advanced Key Management.

Sonexa KeyXchange is a powerful, fully digital platform for the secure distribution, management, and provision of device keys. The system ensures that only the rightful owner has access to the associated keys and is based on the Closed-Sealed-Letter principle to meet the highest security requirements.

The platform is designed for both distributors and metering service providers as end users, companies, or utility companies. Distributors can securely forward device keys to their customers without gaining access to the keys themselves. End users receive simple and secure access to their device keys for installation, commissioning, and operation.

KeyXchange provides an intuitive web-based user interface as well as a REST API for seamless integration into existing systems. The platform supports flexible assignment processes using push and pull methods: distributors can either assign device keys to their customers, or end users can take over the devices themselves by scanning a QR code. The interface is optimized for mobile devices, making self-assignment particularly easy directly on site.

Thanks to its scalable architecture, Sonexa KeyXchange is suitable for companies of all sizes and enables efficient management of growing customer and device inventories. The platform thus combines the highest security standards with simple, flexible, and future-proof management of device keys.
