Hey Guys, I bought two keys on Ebay last year for 30 bucks and a couple of dollars for shipping. I got them cut at the local hardware store, and programmed them myself with instructions that came with the keys. I have four now for my truck, and I was told by the local ford dealer that I could have eight, but that after 8, it starts throwing the first ones out! Please check, as I believe I recall that only one original key is required, not two, but you can program them yourself. ( Lord knows what I did with the instructions, that would clear it up! ) Oh by the way, when you get the key cut, you can test the newly cut key before you program it by seeing if it will turn in the door or tailgate lock.
Remember I got two of them for $30.00! A lot cheaper than $157.00 for one!
I also have a cut, but non-programmable ford key that I keep in my wallet, just in case I lock the keys inside. I can get in the truck, I just can't start it!
