The Kaba expert plus system is custom designed to suit situations where access to authorised areas must be restricted or controlled. The diversity of the Kaba key system gives customers the ability to have simple Keyed Alike systems operated by one key, through to a specific grand master key system.
The system has vastly improved resistance to methods of gaining entry via the cylinder.
The 22 possible pin positions arranged in 4 rows, together with the unique pinning methods, permit Master Keying without using master pins or wafers and their inherent lowering of security. Combined with uniform length of top and bottom pins and springs, these features provide the best possible situation to guard against picking, raking, impressioning or manipulation with a key.
