If the side milling depths and angles are the same as the finger pins, the plug will rotate forcing the sidebar to retract within the plug. If they are not, the plug will not be able to rotate. If the set-up key rotates, continue with Step 10. If not remove the finger pins and start over.
Step 10. Carefully rotate the plug counterclockwise 180 degrees until the pin chambers are vertical.
Step 11. Load each pin chamber with the correct bottom pin and if master keyed, the correct master wafer.
Step 12. Once each chamber is loaded, test the operation of the change key and the top master key. With either key inserted into the plug, only master wafers can be above the outer diameter of the plug.
Step 13. Using the set-up key, load the plug into the housing. Test the operation of the change key and the top level master key being careful the plug does not slide out of the housing.
Step 14. Assemble the lock cylinder.
Note: When combinating a Primus lock cylinder, the pin tumbler springs are different from the finger pin springs, and are not interchangeable.
