I dont remember the actual name brand but you are describing a very low cost cylinder and lock. The cylinder has two tabs that will fit into slots in the lock. The cylinder is then rotated so it cant fall out and the set screw is tightened to prevent rotation. These usually have a plastic trim ring. The lock may be threaded and if so, the cylinder can be replaced with any threaded cylinder with the AdamRite cam and an appropriately sized trim ring.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
