Abstract

A rekeyable lock cylinder comprising: a cylinder body having a longitudinal axis and defining a longitudinally spaced, radially-aligned first plurality of pin chambers, each of said first plurality of pin chambers adapted to house a corresponding first pin, said cylinder body further defining a longitudinally extending slot therethrough; and a plug assembly disposed in said cylinder body, said plug assembly comprising a plug body defining a second plurality of pin chambers, each of said second plurality of pin chambers adapted to house a corresponding second pin, said plug body rotatable within said cylinder body between a first position and a second position, said first position aligning said second plurality of pin chambers with said first plurality of pin chambers, said second plurality of pins removable from said second plurality of pin chambers when said plug body is in said second position.

Claims (8)

1. A rekeyable lock cylinder comprising

a cylinder body having a longitudinal axis and defining a longitudinally spaced, radially-aligned first plurality of pin chambers, each of said first plurality of pin chambers adapted to house a corresponding first pin, and said cylinder body further defining a longitudinally extending slot therethrough;

a plug assembly disposed in said cylinder body, said plug assembly comprising a plug body defining a clip-receiving slot extending transverse to said longitudinal axis an a second plurality of pin chambers, each of said second plurality of pin chambers adapted to house a corresponding second pin, said plug body rotatable within said cylinder body between a first position and a second position, said first position aligning said second plurality of pin chambers with said first plurality of pin chambers with said slot, said second plurality of pins removable from said second plurality of pin chambers when said plug body is in said second position; and

a plug clip adapted to prevent longitudinal separation of said plug body from said cylinder body, and adapted to prevent removal of a slot cover except when said plug body is in said second position.

2. A method for rekeying a lock cylinder, comprising the activities of:

inserting a key into a plug assembly disposed in a cylinder body, said cylinder body having a longitudinal axis and defining a longitudinally spaced, radially-aligned first plurality of pin chambers, each of said first plurality of pin chambers adapted to house a first pin, said cylinder body further defining a longitudinally extending slot therethrough, said plug assembly disposed in said cylinder body, said plug assembly comprising a plug body defining a clip-receiving slot, and a second plurality of pin chambers, each of said second plurality of pin chambers adapted to house a second pin;

rotating said plug assembly with said cylinder body from a first position to a second position, said first position aligning said second plurality of pin chambers with said first plurality of pin chambers, said second position aligning said second plurality of pin chambers with said slot, and

removing said second plurality of pins from said second plurality of pin cambers when said plug body is in said second position, wherein said activity of removing said second plurality of pins is performed without removing a plug clip adapted to prevent longitudinal separation of said plug assembly from said cylinder body.
