Devices, methods, and systems for keying a lock assembly
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 method for keying a lock cylinder comprising a cylinder body and a plug assembly disposed in said cylinder body, said plug assembly comprising at least one pin and at least one corresponding rack for relocating said at least one pin, said lock cylinder defining a tool-receiving aperture, comprising the activities of:
moving a carrier comprised by said lock cylinder from a first position to a second position, the carrier adapted to engage the at least one rack;
inserting a rack alignment tool into the tool-receiving aperture;
receiving the at least one rack in at least one corresponding slot defined by the carrier;
inserting a key into the plug assembly;
moving the carrier from the second position to the first position; and
engaging the at least one rack with a corresponding pin from the plurality of pins.
2. The method for keying a lock cylinder of claim 1 , further comprising the activity of:
learning the key.
3. The method for keying a lock cylinder of claim 1 , further comprising the activity of:
removing a rack alignment tool from the tool-receiving aperture.
4. The method for keying a lock cylinder of claim 1 , wherein the rack alignment tool comprises:
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 at least one rack, each prong from said plurality of prongs dimensioned lengthwise to relocate to a first predetermined position said corresponding one of said at least one rack, said first predetermined position common to each of said at least one rack, each prong from said plurality of prongs comprising a second longitudinal end connected to said base plate.
5. The method for keying a lock cylinder of claim 1 , wherein the rack alignment tool comprises:
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 at least one rack, each prong from said plurality of prongs dimensioned lengthwise to relocate to a first predetermined position said corresponding one of said at least one rack, said first predetermined position common to each of said at least one rack, 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 engageable with said at least one rack in an unengaged position.
