RETROFIT LOCK ABSTRACT OF THE DISCLOSURE A lockset having a rim mounted latch bolt and a dead bolt arranged in side-by-side relation on a door for engagement within side-by-side openings in a common strike. The dead bolt projects from an edge of the door and is operated from the inside by a turnpiece assembly and from the outside by a key operated lock cylinder mounted in fixed position relative to the door. Inside and outside lever handles journalled for limited angular movement on the turnpiece assembly and on the lock cylinder, respectively, operate the latch bolt from the inner and outer side of the door. The turnpiece assembly is connected to the lock cylinder and the inside lever handle is connected to the outside lever handle through a single transverse bore formed in the door. The present lockset may be installed on a door to replace a cylindrical lockset of key-in-knob type having a single latch bolt without boring an additional hole in the door.
