AA new dimension of access control. Simons Voss was founded to produce a system which makes our customers’ lives and work more secure, convenient and cost-effective. To this end, we have used digital technology to revolutionize classic mechanical locking systems and integrated access control functions. 

Simons Voss sets international standards. Our idea of using a digital transponder rather than a standard key has taken off the world over. We have successfully and consistently realized this vision with our radio-controlled, wireless locking and access control system. Simons Voss is the undisputed technology leader in the rapidly growing market for digital, battery-operated locking and access control systems. We have installed more than 10,000 systems around the world, proving that our vision has already become reality. 

Major presence in many countries. Simons Voss now has local branches in Austria, Great Britain, France, Italy, Spain, the Benelux, Singapore, the Middle East and the United States. The headquarters in Unterfoehring near Munich is home to administration, central departments and development. Production and logistics are based in Petersburg near Jena.
