An interchangeable key system having a non-spheroidal head with a one-piece construction, where the head includes a side surface that spans the periphery, a top end, a bottom end that is opposite the top end, and a bore positioned within the side surface and at the bottom end. The key system also includes a blank having a blade at a distal end and a projection at a proximal end; where the blade is adapted for insertion into a lock, and at least a portion of the projection is adapted for insertion into the bore. The key system also includes means for removably connecting the blank and the head together, such that the blank is generally fixed relative to the head when the two are connected.
