From a local locksmith service to national security experts

Schlüssel Schumann GmbH has been in the centre of Iserlohn since 1945. The traditional owner-managed and innovative company is now in the 3rd generation.
With its 16 staff members – including four master craftsmen – Schumann-Sicherheit now concerns itself with the development of systems that meet the permanently growing security demands and regulations of both private and commercial customers.

We mainly concern ourselves with mechanical and electronic burglary protection,
locking systems, surveillance and access controls.
