so last night i was having a few beers with my friends and i had my car parked in my driveway...so, the place i live in, im able to keep my keys in my car without worrying, so i tossed them onto my dashboard (still used to my 94 f150) and well...my truck had mesh over the window defroster vents.......

long story short, my keys are in the air duct haha, like i cant even see them

 

looks like you need to get 4 prong flexible pickup tool or flexible magnet. or start pulling out the defroster ducts.
