Electromechanical lockset

A lockset, comprising:

• an exterior assembly configured for mounting on an exterior surface of a door having a standard door preparation comprising a standard cross-bore and a pair of standard fastener bores positioned on opposite sides of the standard cross-bore, the exterior assembly comprising:
• an exterior escutcheon;
• an exterior window mounted on the exterior escutcheon;
• a credential reader assembly including a multi-tech credential reader positioned in the exterior escutcheon and aligned with the exterior window, the multi-tech credential reader operable to read a credential via each of a first protocol and a second protocol, and to transmit data relating to the credential in response to the reading;
• an exterior spring cage housed in the exterior escutcheon;
• an exterior spindle rotatably mounted to the exterior spring cage and extending through the exterior escutcheon in a longitudinal direction;
• and
• an exterior backplate coupled to the exterior escutcheon and retaining the exterior spring cage and the multi-tech credential reader within the exterior escutcheon;
• an interior assembly configured for mounting on an interior surface of the door, the interior assembly comprising:
• an interior escutcheon;
• a control assembly housed in the interior escutcheon in communication with the credential reader assembly via a first plurality of wires, the control assembly including a controller configured to receive the credential data, to compare the credential data to an authorized credential, and to issue a signal in response to the comparing;
• an interior spring cage housed in the interior escutcheon;
• an interior spindle rotatably mounted to the interior spring cage and extending through the interior escutcheon in the longitudinal direction;
• and
• an interior backplate coupled to the interior escutcheon and retaining the interior spring cage and the control assembly within the interior escutcheon;
• a center assembly configured for mounting in the standard door preparation, the center assembly comprising:
• a chassis configured for mounting in the standard cross-bore, an outer surface of the chassis defining a channel extending in the longitudinal direction, and wherein the first plurality of wires extends along the channel;
• a locking member having an unlocking position and a locking position;
• an electromechanical actuator in communication with the control assembly via a second plurality of wires, wherein the controller is configured to issue the signal through at least one of the second plurality of wires, and wherein the electromechanical actuator is configured to move the locking member between the locking position and unlocking position in response to the signal;
• and
• a retractor slidably mounted to the chassis and configured to move laterally in response to rotation of the interior spindle;
• wherein, with the locking member in the unlocking position, rotation of the exterior spindle is operable to move the retractor laterally;
• and
• wherein, with the locking member in the locking position, the exterior spindle is not operable to move the retractor laterally;
• a pair of posts extending in the longitudinal direction from one of the exterior spring cage and the interior spring cage, wherein the pair of posts are configured to be received in the standard fastener bores;
• and
• a pair of fasteners extending in the longitudinal direction from the other of the exterior spring cage and the interior spring cage, wherein each fastener is engaged with a corresponding one of the posts.
