You can unlock with a slim jim unless they changed the lock stuff for the 04's. I used to work as a fabricator and in my 03 I somehow locked my keys in the car. The one guy has used these before and said we can easily make one. We used the metal straps that come on palettes and hold the sheet sheet down. Cut a 3 foot piece and on the one end make an angled notch in it. It sure worked and now I carry it with my and helped a few people get in their cars.
I know the 97 to 03's dont have a blocker plate but not sure about the o4's. But you slip it down by the handle going towards the back and pull up. It took a few tries and I dont know what im hooking onto but it works. Kind of beats a hangar because you dont have to try pulling the door away and fishing it down. Or just buy one as one suggestion was already said.
