It is not possible to key SFIC and standard cylinders including Schlage FSIC into the same system. A keyway name may be shared between the two key families, but they are different in many ways including the shape or profile of the keyway, pin sizes, pin heights, and pin spacings.
Example: The "E" keyway - A Falcon "E" keyway in a standard cylinder is not the same as an "E" keyway in Falcon SFIC.
