View Patent ↗Certain exemplary embodiments of the present invention provide a lock keying system comprising: a lock cylinder comprising: a cylinder body; a plug assembly disposed in the cylinder body and comprising a plurality of pins and a one-to-one corresponding plurality of racks for relocating the plurality of pins; and a rack alignment tool receiving aperture defined by the lock cylinder; and a rack alignment tool comprising: a base plate; and a plurality of spaced elongated prongs, each prong from the plurality of prongs comprising a first longitudinal end adapted to engage a corresponding one of the plurality of racks, each prong from the plurality of prongs dimensioned lengthwise to relocate to a first predetermined position the corresponding one of the plurality of racks, the first predetermined position common to each of the plurality of racks, each prong from the plurality of prongs comprising a second longitudinal end connected to the base plate, wherein the rack alignment tool is adapted to restrain a carrier assembly comprising the plurality of racks in an unengaged position wherein the plurality of racks are unengaged with the plurality of pins.
1. A lock keying system comprising:
a lock cylinder comprising:
a cylinder body;
a plug assembly disposed in said cylinder body and comprising a plurality of pins and a one-to-one corresponding plurality of racks for relocating said plurality of pins; and
a rack alignment tool receiving aperture defined by said lock cylinder; and
a rack alignment tool comprising:
a base plate; and
a plurality of spaced elongated prongs, each prong from said plurality of prongs comprising a first longitudinal end adapted to engage a corresponding one of said plurality of racks, each prong from said plurality of prongs dimensioned lengthwise to relocate to a first predetermined position said corresponding one of said plurality of racks, said first predetermined position common to each of said plurality of racks, each prong from said plurality of prongs comprising a second longitudinal end connected to said base plate,
wherein said rack alignment tool is adapted to restrain a carrier assembly comprising said plurality of racks in an unengaged position wherein said plurality of racks are unengaged with said plurality of pins.
2. The lock keying system of claim 1 , wherein each of said plurality of prongs has a substantially identical length.
3. The lock keying system of claim 1 , wherein an insertion distance of said plurality of prongs constrained by a contact of said base plate with said lock cylinder.
4. The lock keying system of claim 1 , wherein for each rack of said plurality of racks, a longitudinal axis of said rack is parallel to and non-coaxial with a longitudinal axis of said rack's corresponding pin.
5. The lock keying system of claim 1 , wherein said plug assembly further comprises a carrier assembly moveable parallel to a longitudinal axis of the cylinder body, said carrier assembly comprising said plurality of racks.
6. The lock keying system of claim 1 , wherein each pin comprises at least one tooth.
7. The lock keying system of claim 1 , wherein each rack comprises at least one tooth.
8. The lock keying system of claim 1 , wherein each rack comprises at least one tooth spaced a predetermined distance from an end of said rack.
9. The lock keying system of claim 1 , wherein each rack comprises at least one tooth spaced a predetermined distance from an end of said rack, said distance dependent on a lock brand.
10. The lock keying system of claim 1 , wherein each rack comprises at least one tooth spaced a predetermined distance from an end of said rack, said distance dependent on a manufacturer's key depth.
11. A lock keying tool for a lock cylinder comprising a cylinder body and a plug assembly disposed in the cylinder body and comprising a plurality of pins and a one-to-one corresponding plurality of racks for relocating the pins, said lock cylinder defining a tool-receiving aperture, said lock keying tool comprising:
a base plate defining a first face and a second face, said first face opposing said second face;
a plurality of spaced elongated prongs, each prong from said plurality of prongs comprising a concave first longitudinal end disposed on a first portion of said prong and adapted to engage a corresponding one of the plurality of racks, each prong from said plurality of prongs defining a longitudinal axis and longitudinally dimensioned to relocate to a first predetermined position the corresponding one of the plurality of racks, the first predetermined position common to each of the plurality of racks, each prong from said plurality of prongs comprising a second longitudinal end disposed on a second portion of said prong and connected to said base plate; and
a handle connected to said second face of said base plate.
12. The lock keying tool of claim 11 , wherein each of said prongs is perpendicularly connected to said first face.
13. The lock keying tool of claim 11 , wherein each of said plurality of prongs has a substantially identical length.
14. The lock keying tool of claim 11 , wherein said first face is parallel to said second face.
15. The lock keying tool of claim 11 , wherein said base plate defines a segment of an annulus.
16. The lock keying tool of claim 11 , wherein said handle is perpendicularly connected to said second face of said base plate.
