Product Description
Need a drop-in SFIC core that's ready to go out of the box? The Arrow Lock 7100CRP 1C US4 is a 7-Pin combinated SFIC core in C - Best keyway, Satin Brass (US4/606). Ships pinned and keyed different (KD) with 2 operating keys and 1 control key — plug it into any standard SFIC housing, turn the key, done.
Includes 2 Operating Keys + 1 Control Key. The control key has completely different bitting than the operating keys — it works a second shear line inside the figure-8 core to release the retaining lug, letting you swap cores in seconds without disassembling the lock.
Pro-Tip from Our Locksmiths: Ships keyed different (KD) with 2 operating keys and 1 control key. The control key has completely different bitting — it works a second shear line inside the figure-8 core to release the retaining lug. Don't lose the control key — without it you can't swap or remove the core from the housing. Need keyed alike (KA) or master keyed (MK)? Call (877) 365-5625 before ordering.
