Evva Architectural Hardware: Door Furniture

EVVA is an Austrian, family-owned security manufacturer based in Vienna, specialising in high-end mechanical and electronic locking systems for everything from homes to large, complex master-keyed organisations. The company was founded in Vienna in 1919, and it still runs research, development, and production from its Vienna headquarters, exporting globally. 

In the trade/spec world, EVVA’s reputation is built on serious key control and master key system engineering—locks designed not just to resist attack, but to keep access hierarchies manageable at scale (offices, hospitals, residential complexes, universities, etc.). 

A couple of EVVA’s standout mechanical platforms get referenced constantly:

• ICS (Inner Code System) – a reversible key system aimed at highly complex master key structures, with EVVA citing long patent protection (into the 2030s, depending on jurisdiction). 

• MCS (Magnetic Code System) – EVVA positions this as a top-tier system for sophisticated master keying, with a strong anti-copying story (including resistance to modern replication methods). 

They also explicitly brand themselves around innovation: EVVA talks about holding 200+ patents and frames its history as “start-up energy since 1919” (which is an absolutely deranged sentence for a century-old lock company, but I respect the audacity).
