Hi! Thank You!
The Problem is - evva - is the "top-dog" (Platzhirsch in german) here - and as so often in Austria prices are "controled"
That means - you have to pay 43.- €uro for one spare key in the newer times if you got ther key blank from evva directly. (Altanlagen-Zuschlag Altschließanlagen-Zuschlag is the magic word therefore...)
This phenomen is an european phenomen - but specialy an Austrian - to pay a lot for nothing.
(You can find - spare parts which cost some cents in US - costs 20 Euro and more in Europe. Bearing, seals and such parts are often in a "controled" market in Europe.
The possibility of chanding the hole system is academic - but thanks - the systems in such Houses are very big - and for one single user; how should he manage this??!
The idea is not bad - and the best way would be to change to an other supplier - international or german. The marked control there is not so strong there as in Austria (the same old story not only "since 1919" like evva)
I changed my key sytem on my private doors this way - maybe I have to go to a metalworking company - it should be always cheaper to pay 43.- € for one key or 200.- for 5 pcs !! (Another possibility is to contact the "Arbeiterkammer" - but the more argument for equal prices as for fair prices in our ideological homecountry...)
If somebody can tell me the code for a Key blank (ein Schlüsselrohling - Rohling means "uncutted") it will be fine - Thanks
