I've searched and searched and can't find out what brass key goes to my 2002 Supra SSV Launch. The sheared in half key I pulled out measures about 1 1/2 inches long and close to a quarter inch wide and quater inch tall when I put the two pieces together. Everywhere I go seems to be 2 1-8 inches long. Am I supposed to cut it shorter? Anyone have a direct link to the current part? Thanks ahead for any help!
