To facilitate consistent control-level picking, two techniques that can be used: applying pressure to the control lug or shell or inhibiting the ability for the operating shear line to be picked.

Often control levels are difficult to rotate. The primary reason why operating levels are easier to pick than control levels is the rotation of the operating level offers less resistance than the control level. If you donвЂ™t optimize your picking technique you will almost always pick the operating level.

The locks have two different shear lines, the operating level that allows the lock to be accessed, and the control level that allows the core to be pulled from the lock. Picking Figure-Eight Interchangeable CoresДЇigure-eight interchangeable cores can be difficult and time-consuming to pick, especially seven-pin cores. If rekey job consists of many locks using the same control key, the options are: to sacrifice one lock or lock cylinder to remove a core and decode the control key to pick the control level of the core. If the rekey job entails one lock, removal options are: to drill out the core or housing and replace it with a new one or to pick the control level (shear line) of the core. To rekey the lock or lock cylinder, the core must be removed. Without a control key, the core is completely locked. When the rotation stops, the core is ready for removal by pulling it out of the cylinder, knob, lever, etc. Interchangeable cores are normally removed by inserting the control key then turning the key clockwise about 15 degrees. Unlike other commercial lock cylinders, figure-eight (small format) interchangeable cores require special removal techniques when keys are not available.
