The Pro-1 product comes with two keytips (7-pin and 8-pin) with the choice
of a free 3rd keytip of your choice (Small Kryptonite or American
Padlock ) mailed to you upon our receipt of your registration card.
Additional keytips or other spares can be purchased for either product
at a later date.
How the Pro-1 works:
While applying bias to the cylinder, tap each of the pick element control
buttons individually, with the tip of your finger. You are feeling
each to find the primary locking pin. One or more of the pins will
resist being pushed down. The rest will be bouncy, because of the
action of the cylinder springs. While holding the pick vertical
to the lock cylinder and biasing the pick to maintain the pressure on
the primary locking pin, slowly turn the pick element thimble down.
This will cause the pick element to extend, pushing the combination pin
downward. When the pin reaches the shear line, you will hear / feel
a click. The pin is picked to a shear line. It may be a
false or true shear line, we cannot tell. It makes no difference
at this point. The pin is picked. Relax the turning tension
and then re-bias the pick in the opening direction. Test the control
buttons again, to find the nex primary locking pin or pins. Perform
the screw down operation to find the shear line for each position, and
release the turning tension. Continue testing to find the binding
pins. As each pin is picked, another will bind. Continue this
operation until the cylinder turns. (Robert Seiveking 2001)
