When you are confronted with a SFIC (small format interchangeable core) cylinders and the face of the cores are painted or stained, try one of the following codes to create the control key.

COLOR	KEYWAY	OPERATING CUTS	CONTROL KEY CUTS

The above codes may or may not work on every construction core. Remember, all SFIC core numbers are read from tip to bow.
