This is the transmission park/lock cable!
Follow the steps below if the ignition switch lock cylinder is seized or won't rotate (or the key is lost)
1.Protect the immediate work area with suitable material such as clean shop towels or a clean fender cover.
2.Locate the surface for the ignition switch lock cylinder release button (2) on the plastic ignition switch housing and center punch a location on the rib (1) approximately 3/8 inch rearward toward the key entry end from the cylinder release button.
3.Carefully drill a pilot hole through the plastic housing with a 1/8 inch drill bit.
4.Carefully drill a larger hole at the pilot location, and slightly into the ignition switch lock cylinder surface to break the release button retaining spring using a 9/32 inch drill bit.
5.Remove portions of the broken spring from the hole using a small suitable tool.
6.Grasp the ignition switch lock cylinder and remove it from the switch housing.
7.Remove any plastic flashing from the drilling operation, and using compressed air blow out the ignition switch assembly.
NOTE: It doesn't matter if you get another key made at the dealership, you are still going to have to perform the passlock 10 minute relearn procedure.
