Accentra FN11 6-Pin Control Key Blank | Yale Multiplex Key System

The Accentra FN11 6-Pin Control Key Blank (formerly Yale) is a critical component for managing and maintaining high-security Large Format Interchangeable Core (LFIC) systems. This specialized control key blank is engineered to engage the locking lug of an interchangeable core, allowing for the immediate removal or installation of the core without disassembling the entire lock. Designed for precision and longevity, the FN11 is the industry standard for facility managers overseeing large-scale master key systems.

As part of a multiplex keyway system, the FN11 offers superior flexibility for expanding security networks. Whether you are managing a single building or a multi-site campus, this 6-pin blank provides the mechanical depth required for complex, multi-level keying hierarchies.

Understanding Keyway Sections & Multiplex Systems

• Multiplex Keyway Expansion: Unlike simplex keyways that stand alone, multiplex keyways can be integrated to expand a system. This allow for multi-section keys (like the GV section) to operate across multiple single-section cylinders (such as GA, GB, GG, and GH).
  
• Control Function Precision: The FN11 is specifically designed as a control key, meaning it is cut differently than standard user keys to facilitate core changes in LFIC housings.
• Accurate Identification: To ensure compatibility, the key section is determined by viewing the profile of the key from the bow toward the tip.
• Industrial Durability: Manufactured from high-quality nickel silver or brass alloys to prevent snapping and ensure smooth operation within the cylinder over years of use.
