The following is an exerpt from my story "Jungle Red" which took place about 3 miles east of Fort San Lorenzo, Panama. It seems applicable in this case.

We sat in the car for a while and finally the rain almost quit so we got out, got our bags, machete, poles, etc, locked the car and started up the beach, looking for orchids that grow on the sea cliff. Within half an hour we found all we wanted and started back to the car. On the way I put my hand in my pocket and noted that the keys were NOT there. The rain had picked up again and we were getting wet, although it was warm, and thus not uncomfortable. We got back to the car and looked in and sure enough! The keys were in the ignition. The trunk was unlocked but other than something with which we could break a window, no help was apparent. I tried fitting the machete blade between the glass and the door but really couldn't see anything I could do that way. I looked around for a coathanger but didn't see one anywhere and was not sure how I could get to anything that would let us in with it anyhow. I found some military WD-1 field wire, which was strong but not stiff, also no help. Finally my eyes landed on the wiper arms. I took one off, took off the blade and bent it into a "J" shape, and stuck it in past the weatherstrip on the vent window, and would have been able to turn the latch with it, except that I couldn't push the button to unlock it. So I took off the other wiper arm, removed the blade and bent it into an "L" shape, stuck it through the weatherstrip and was able to pull it against the button. In a rare stroke of coordination, I put both bent wiper arms through the weatherstrip (while my friends watched wide-eyed), pushed the button with the L-shaped one and turned the handle with the J-shaped one and had the vent window open almost immediately. I reached in and opened the door, then quickly retrieved the keys through the open door. Then, I calmly straightened the arms and reinstalled the blades on them, and snapped them on the wiper shafts. I guess I didn't hurt them too badly because they were still on the car when I eventually sold it about 9 years later.

Hope this helps,
