Patent number: 7007528Abstract: A re-keyable lockset that employs pairs of first and second pins. Coupling of the first and second pins to one another defines a key profile for a mating key. A second key with a different key profile may be installed to the lockset when the first and second pins are uncoupled from one another. Thereafter, the first and second pins may be re-coupled to one another to define the key profile of a new mating key. A method for re-keying a lockset is also provided.Type: GrantFiled: April 1, 2004Date of Patent: March 7, 2006Assignee: Newfrey LLCInventors: Gerald Chong, Steven Armstrong

Publication number: 20050155399Abstract: A rekeyable lock cylinder includes a cylinder body with a plug body and carrier sub-assembly disposed therein. The plug body includes a plurality of spring-loaded pins and the carrier assembly includes a plurality of racks for engaging the pins to operate the lock cylinder. The racks and pins move in a transverse direction, in response to insertion of a first valid key into the lock cylinder, to unlock the lock cylinder. The carrier moves in a longitudinal direction, in response to insertion of a tool in a tool-receiving aperture, from an operating position to a rekeying position. In the rekeying position, the racks are disengaged from the pins and a second valid key can replace the first valid key. Rotation of the plug body from the rekeying position with the second valid key in the lock cylinder obsoletes the first valid key.Type: ApplicationFiled: February 10, 2005Publication date: July 21, 2005Inventors: Steven Armstrong, Gerald Chong, Richard Veltman

Patent number: 6745602Abstract: The present mechanism provides a quick install lockset mechanism having a semi-permanent mechanical connection between an interior lock assembly and an exterior lock assembly. The exterior lock assembly includes a pair of threaded fasteners extending through a preformed hole in a door, and the interior lock assembly includes a rose liner configured to rotatably engage the fasteners to connect the interior and exterior lock assemblies. The interior lock assembly rose liner includes a pair of raised contoured portions having openings for receiving the fasteners and ramps for guiding the fasteners to the openings. In addition, the interior lock assembly includes a knob insert and a turnpiece guide. The knob insert is disposed in the knob and the turnpiece guide is removably disposed in the knob insert. A turnpiece is disposed in the turnpiece guide and is thereby aligned with an operating member extending from a lock cylinder in the exterior lock assembly.Type: GrantFiled: July 16, 2001Date of Patent: June 8, 2004Assignee: Newfrey LLCInventors: Frank Nakasone, Steven Armstrong
