A doorknob includes a hollow body and a spindle securely mounted in the body to turn therewith. An outer end portion of the spindle includes two diametrically opposed tongues each having an outer end. An end face plate is removably and rotatably received in a compartment in an open outer end of the body. The end face plate includes opposite inner and outer faces. The end face plate further includes a substantially 8-shaped hole extending from the inner face through the outer face. A projection extends perpendicularly from the inner face of the end face plate. The projection defines a space for receiving the outer ends of the spindle. A lock core is removably mounted in the 8-shaped hole of the end face plate and includes a portion received between the outer ends of the tongues of the spindle.
