From locksmith's shop to high-tech enterprise

CES is an internationally leading manufacturer of locking systems and electronic access control systems with a history that dates back to 1840.  The company is based in Velbert and pioneered the industrial production of locking cylinders in Germany.  When Carl Eduard Schulte took over the firm from his father in 1857, he gave it the name it still bears today - C.Ed.Schulte Zylinderschloßfabrik or CES in short.  Under this name, the company established its national and international reputation as a specialist for reliable security systems.

CES offers a range of time- and identity-based access control solutions.  Using state-of-the-art radio and transponder technology, CES products afford superior flexibility in the design of access authorizations that offer a maximum of security.

CES manufactures high-quality mortise locks for demanding industrial and commercial building applications and offers innovative lock solutions for special requirements. 

CES has about 430 employees and generated sales of 42 million euros in 2015.  In addition to its Velbert production location, CES also operates a manufacturing facility in Romania.

CES has sales offices in many European countries and is globally represented through various partner companies.
