KESO Mechanics

The reversible key technology in perfection.

KESO master key systems open up new dimensions. KESO locking cylinder are a masterwork of precision engineering made in top quality. All of the 7 KESO key shapes have a design protection and can be combined in the same system. More drilling picture variants and the possibility to shift the key channel in the plug enables that we can permutate very big and sophisticated master key systems.
