  • Patent number: 8056379
    Abstract: A lock cylinder that includes a housing and a plug. The housing includes a wall that defines a hollow portion and a pin portion that defines a first pin chamber that is configured to receive a first pin. The plug includes a body rotatably housed within the hollow portion of the housing. A key slot is defined in the body in part by a pin resting surface 90, and a second pin chamber is disposed in communication with the key slot. A second pin is disposed within the second pin chamber and is configured to engage the pin resting surface 90. An engagement member is disposed within the body as a separate piece, and engaged with the second pin to space the second pin a distance from the pin resting surface 90 in the absence of a key in the slot.
