An exemplary lockset is configured for installation in a standard door preparation, and includes an exterior assembly, an interior assembly, and a center assembly connecting the exterior and interior assemblies. The exterior assembly includes an exterior escutcheon which houses a credential reader assembly including a multi-tech credential reader. The interior assembly includes an interior escutcheon which houses a control system. The center assembly includes a chassis, an outer surface of which may define a channel. The credential reader assembly is in communication with the control assembly via a wire harness, a portion of which may pass through the channel.

A door lock, assembled in a door sheet, is provided, wherein the door lock has a latch, a first locking mechanism, and a second locking mechanism, wherein the door lock is adapted to be assembled on the door sheet through coupling the first locking mechanism and the second locking mechanism onto the latch. The first locking mechanism and the second locking mechanism have a spiral resilient member screw and abut on a bulge so as to lock the first locking mechanism and the second locking mechanism corresponding to the door sheet. At the same time, an engaging member of the second locking mechanism can both resiliently abut against an upper engaging member and a lower engaging member of the first locking mechanism, so as to limit the lateral movement of the first locking mechanism and the latch, which is not only assembled conveniently. Besides, the engaging and abutting structures among the engaging member, the upper engaging member, and the lower engaging member as well as the spiral resilient member and the bulge are very simple and effective.

An arrangement for a lock system comprising a latch spindle for engaging a follower and comprising a handing structure; an outer spindle comprising an outer engaging structure configured to engage the handing structure; and an inner spindle comprising an inner engaging structure configured to engage the handing structure independently of the outer engaging structure; wherein the handing structure, the inner engaging structure and the outer engaging structure are configured to cooperate such that a first handing can be set by a first latch position of the latch spindle, and a second handing can be set by a second latch position of the latch spindle; and wherein the handing structure comprises an angular clearance such that the inner spindle can drive the latch spindle relative to the outer spindle by engagement between the inner engaging structure and the handing structure.
