Gege pExtra Plus Master Key System 10 Cylinders 30/30mm Nickel EI60 Patented Profile

Product Overview

The System master key based on Gege pExtra Plus cylinders is a high-security access solution commonly specified for commercial, institutional, and mixed-use facilities requiring patent protection and structured key hierarchy. This package contains ten double-sided nickel cylinder inserts (30/30 mm each), thirty individual keys, three master keys, and a security card encoding the scheme, compliant with European patent protection until 2032 and EI60 fire resistance. Individual cylinder profiles are proprietary, requiring the security card for authorized extension or key duplication.

A standout feature of this system is the use of advanced pExtra Plus cylinders with both patented anti-copy key profiles and active side tumblers that block unauthorized key use. This technology eliminates risks of illegal key reproduction and reduces liability for facility managers needing robust access control in environments such as office complexes, schools, and hotels. Especially recommended for bulk procurement by property management companies and installers seeking bespoke master key structures managed via registered security cards.
