Abstract
A lock core and key assembly includes a core body, a core plug having a core plug insert-receiving aperture, a core plug insert positioned in the core plug insert-receiving insert, and a key. The core plug insert has a taper and the key has a bow and a shank with a taper that aligns with the taper of the core plug insert.
Claims13
A method of assembling an interchangeable lock core comprising the steps of
- providing
- a core body having a plurality of pin- and spring-receiving apertures and a plurality of ejector pin-receiving apertures in line with the plurality of pin- and spring-receiving apertures and sized to receive an ejector pin,
- a core plug having a longitudinal axis, a first end, a second end longitudinally spaced apart from the first end, a side wall extending between the first and second ends of the core plug, a plurality of pin-receiving apertures, a keyway, and a core plug insert-receiving aperture positioned in the side wall between the first and second ends of the core plug, the keyway having an opened end positioned on the first end of the core plug and sized to receive a key, and
- a core plug insert having a longitudinally extending, tapered surface having a length at least one quarter of a length of the keyway,
- positioning the core plug in the core body with the plurality of pin-receiving apertures in line with the pin- and spring-receiving apertures of the core body, and
- positioning the core plug insert into the core plug insert-receiving aperture of the core plug with the longitudinally extending, tapered surface of the core plug insert defining at least a portion of the keyway, the keyway having a profile configured to match a profile of a key configured to unlock the interchangeable lock to allow the core plug to rotate relative to the core body.
