Also, this is a work vehicle and I have no idea if it even has the remote entry system...any way to determine if it is an installed option????

did you see that you posted in Chevy?
I'd search the ford thread, if no one has anything:

http://www.motorcraftservice.com/vdirs/retail/default.asp

go here, then on the left, hit "owner's info"
then pick your vehicle (95-06) and you can download your owner's manual (should have keyless remote info on about p150?)

hope this helps.
