Best SFIC Core with Control Key

SFIC core with control key. Control keys (which can also be mastered, but rarely are) can rotate the plug only about 20 degrees but also disengage the retaining tab (shown here in the unlocked state), allowing the core to be pulled out from or installed into a lock housing. Image taken with a Nikon D-100 digital camera with a Nikkor 85mm 1:2.8D tilt/shift macro lens (with Kenko extension tube). Lit by electronic flash and various reflectors.
