  • Rekeyable lock cylinder assembly with adjustable pin lengths
    Publication number: 20050172687
    Abstract: A rekeyable lock cylinder includes a plug body and a backing rack that cooperate to define a plurality of pin chambers within the lock cylinder, with each of the pin chambers housing a corresponding pin. Movement of the backing rack changes the configuration of the pin chambers, thereby allowing the corresponding pins to change configuration to match the bitting on a valid key.
