The KILLEEN SECURITY PRODUCTS 207CA04KD is a 7-pin Small Format Interchangeable Core (SFIC) cylinder finished in satin brass. It ships keyed different with two cut keys and one control key included. SFIC cores are designed for high-security commercial and institutional access control systems where cores can be swapped without removing the lockset hardware from the door. The control key allows a technician to insert and remove the core from its housing without disassembling the lock, making rekeying fast and tool-free in the field.
This core is intended for commercial, institutional, and government applications where a master key or grand master key system is required. It fits SFIC-compatible housings used in mortise locks, cylindrical locks, deadbolts, padlocks, and cabinet locks. The A keyway designation controls key access at the keyway level, supporting restricted key systems. Installation and rekeying are typically performed by licensed locksmiths or access control technicians managing large-scale keying programs.
Designed for use in SFIC-compatible housings that are interchangeable with Best, Arrow, and Falcon Small Format Interchangeable Core systems. Fits mortise, cylindrical, deadbolt, padlock, and cabinet lock housings accepting the standard 7-pin SFIC format.
SFIC core installation and removal requires the control key — never force a core out without it, as doing so can damage the housing. Power down any electrified or access-controlled hardware before servicing associated locksets. Core replacement and rekeying should be performed by a licensed locksmith familiar with SFIC keying systems. Follow applicable local codes and the hardware manufacturer guidelines when installing or reconfiguring keying hierarchies.
