Can I include locks from several different manufacturers in one master key system?
Using an ASSA master key system with other manufacturers’ locks is simple: this is why we produce our cylinders in so many different shapes. As long as the cylinders are all from the same series (for example Ruko 5-pin, Ruko Flexcore or ASSA Twin Combi) then the different shapes may be mixed and matched freely to suit the individual locks.
