Highly-convenient, vertical reversible key systemContract business
WD is a patent-protected, vertical reversible key system with high locking precision. It complies with the complex requirements within a building concerning organisation, user-friendliness, economic efficiency, and of course safety.
The WD system not only includes technical features which offer protection against unauthorized key duplication, manipulation and attacks but also legal security as the key geometry enjoys patent protection. The combination of legal and technical protection against illegal duplication ensures the long-term protection of the operator’s investment.
An effective technical duplication protection against unauthorized key copying is provided by the actively-scanned double undercut in the key section. Due to this undercut, the key cannot be copied with traditional key copying machines because these only operate in two dimensions.
