7. The Interchangeable Core cylinders are constructed to the SFIC
standards that you encounter with many other brands. Keying uses the
same techniques employed for those cylinders.
Master Lock offers IC cylinders keyed to existing key systems if you are
able to supply the combinations for the operating key, the TMK, and
the Control key. Master Lock also has the ability to recreate your entire
key system, including all potential expansion, if you can supply bitting
combinations of all keys that have been used.
At present, Master Lock offers IC cylinders compatible with the A2 and A4 format from the factory. If you are equipped for
pinning SFIC cylinders, you can key the cylinders into an existing A3 system without difficulty. The listing below allows
construction of a correct IC cylinder part number when ordering from Master Lock.
