Abstract: A method for constructing a spinner key chain fob comprising an outer housing and one or more independently rotating members affixed within the housing wherein the rotating member has two cavities diametrically opposed on its perimeter edge; the housing has an internal perimeter, an external perimeter, an aperture extending through the internal perimeter to the external perimeter and a center post diametrically opposed to the aperture; the internal perimeter able to receive the rotating member comprising the steps of: inserting the center post into one cavity of the one or more rotating members; and affixing a pin within the aperture such that the pin extends through the key chain housing into the remaining cavity of the one or more rotating members such that when they are impacted they rotate freely.

Abstract: A spinner key ring with locking interchangeable parts is provided. The locking system consists of a set pin and a locking screw or pin that locks the center piece to the outer ring. The spinner key ring has an outer metal ring with a loop called the earpiece at the top, which connects to a chain and then to a split ring to hold keys. The earpiece itself is drilled through the middle to allow the screw to go through the outer ring and into the centerpiece. The length of the screw is 5 millimeters. On the opposite side of the outer ring from the earpiece is a 3-millimeter fixed pin, which the center piece seats onto. Once the centerpiece is seated, the screw is inserted through the earpiece. Using this system the centerpiece is locked into place and is also interchangeable. The system can be used with any shaped outer ring.
