UPDATE: So far no luck... tried a magnet and pressure washer but nothing. Also tried turning the truck upside down and shaking method a few of you mentioned lol. I believe I hear the key still when using a pressure washer so it must be in a "secure" place. Being 4 hours away from home and busy with wedding stuff, the local dealer couldn't get me in for a few days so I took the risk of driving back home after someone brought me the spare. I have a friend who works at a Ford dealer coming by this week to see what we can do. Going to try my plumbing scope first to make sure the keys still there.
Thank you guys for the help. I have learned an expensive lesson. Will keep you guys updated!
