KIWI is a Berlin-based technology company revolutionizing access control with digital keyless entry systems. Founded in 2012, the company provides comprehensive hardware and software solutions that replace traditional metal keys with smart, cloud-managed digital access.

The KIWI ecosystem includes smart hardware products like KIWI Knauf (digital cylinders), KIWI Klinke (smart door handles), and KIWI Smart Entry for intercom systems, alongside a cloud-based management portal and mobile app for users. With a focus on simplicity, security, and GDPR compliance, KIWI enables property managers to grant and revoke access permissions instantly while eliminating the risk of lost or stolen physical keys.
