it doesn't have a screw in it? there are only two types that i have ever seen used in cars, the type that has a clip that you pull out with a long thing needle nose or hooked rod, and the type that screws onto the gear arm.
jeeps use the clip type but sometimes it is hard to see because there is a little piece of plastic between the handle and the door panel that acts as a slider to keep the handle from wearing out the door panel. all of my cherokees, grand cherokees, comanches, and wranglers we have ever owned had the clips on them.
