A new dimension of security
An important factor for the security of a property is choosing a locking system where the keys and cylinders are equipped with active copy protection. KESO 8000Ω² is the latest generation of mechanical and mechatronic locking systems with new active copy protection. The reversible key system is suitable for both complex and simple locking systems. Thanks to a patent valid until 2034 and functional design protection, the new KESO system offers extremely long investment protection. The system is rounded off with an innovative modular system for problem-free extension or shortening of the cylinders on-site.
