Finally, the total pin stack must equal 23. Since we already have '5' loaded into the bottom chamber, an '8' pin is required to reach 13 (13-5 = 8). The control key operates a second plug dia which is 10 numbers higher than the control key cut (10+3 = 13). Therefore the total bottom pins loaded into the chamber would be '5' (4+1 = 5). The difference between cuts for the change key and master key is '4' (5-1 = 4). In our example, the highest cut between the change key and master key is '1'.

This required a new series of key blade shapes. The small format interchangeable core (SFIC) system invented by Frank Best proved to be the most practical solution for fitting a removable cylinder into a 1 1/4" diameter hole.īecause of cylinder diameter restrictions, the key blank height also had to be reduced. There were other cylinder removal inventions but most were limited to mortise cylinders and involved removing the whole round cylinder while leaving only a thin shell in the door.
