About us

We are a team of more than 50 experts from all four corners of the world and together we are sparking a revolution by putting an end to the 4,000-year-old metal key. In the heart of Berlin on a site covering more than 800 m², we develop, design, test, market, and sell the KIWI digital locking system.


Our Vision

We are convinced that the future of the key is not a key at all. Digital access rights are gradually taking over from the traditional key, making it easier and more secure than ever before to gain access. The act of opening doors is becoming a seamless process – with nothing to think about, no worries, and no physical object. Instead, this is replaced by security, convenience, and enjoyment. This is what we believe in and work on every day at KIWI. In addition to doors, we also want to open people’s minds as well as their hearts!
