The push-button lock arrangement includes a permutation chamber, and, in accordance with the invention, the combination of the permutation chamber can be changed without dismantling the lock arrangement and without the use of special tools. A cam, which is rotated by a simple screwdriver, activates the end of the lock-out slide of the permutation chamber to put the permutation chamber in its reset mode. The lock arrangement also includes a rotating stop member and a stationary stopper. The rotating stop member is connected to the outside door knob so that the rotation of the outside door knob is constrained to a predetermined angle of rotation.

The cross-section of the core body defines a peripheral profile. The core body includes a plug housing and a tumbler pin housing, and at least two separately controllable control elements are mounted in the plug housings. Each of the control elements includes a retainer lug and the retainer lugs are movable between a retracted position, when they are substantially completely within the profile, and an extended position, when they project laterally of the core body outside of the profile.

An elongated bolt extension member is coupled to the bolt head of a door latch, and a pivotally mounted latch cam engages the elongated bolt extension member to slide the latch into and out of its retracted position. The elongated bolt extension member has a top surface with two spaced openings corresponding to two different backset distances. The latch cam extends into one or the other of the openings to adjust the backset distance.
