Finally on board: Kartheuser Immobilien becomes a member of Schlüsselregion e.V.

After six years on the waiting list, it's official: Kartheuser Immobilien will become a proud member of the renowned business association Die Schlüsselregion e.V. on January 1, 2026.

This step marks an important milestone for our company and underscores our deep commitment to the Velbert and Heiligenhaus region.

The key network in the region

The Schlüsselregion e.V. association was founded in 2006 and has since developed into one of the key networks in the region. With around 230 member companies, of which around 10% are service providers, the association forms a strong community that stands for contacts, exchange, and visibility. The Velbert/Heiligenhaus region is known worldwide as a leading location for locking and security technology – the "key region."

"Die Schlüsselregion e.V. is the essential network in the region. We are very pleased to now be an active part of this strong community and to contribute our expertise as real estate agents and experts to the exchange," says Tim Kartheuser, succinctly summarizing the significance of membership.

Getting to know each other in a relaxed atmosphere

The official start of membership was preceded by a personal introductory meeting at our offices in Velbert at Friedrichstraße 97. In a relaxed atmosphere, Dr. Thorsten Enge, managing director of Schlüsselregion e.V., presented the association and its diverse activities. In return, Tim Kartheuser presented his company and his vision for the real estate industry in the region.

We would like to thank Dr. Enge for the warm welcome and look forward to a successful and inspiring collaboration in the service of the regional economy.

We look forward to January 1, 2026, and the opportunities that active participation in the Schlüsselregion e.V. network will bring for us and our customers.
