I have two "ford" keys and two remotes. I will assume my two are master keys. So I will purchase two more and program them, then place the master's away.

 

That's what I do. That way if I lose one I still have the two masters to program another clone. I would order 1 to start and make sure the 2 keys you have are both masters. I don't know of anyway to tell other than to try and program and see if they work.

That's why I asked if there was a way to know if a key is a master key. For all I know I may have a master key and a clone key. I'll order one like you suggested and see.

 

is there any way to ident a master key? both my keys have an 'S' stamped at the top of the shank near the plastic. Is there a PID I could check with Torque or something?

 

Second, I have found several "procedures" on YouTube and such. None have worked for me. Do y'all know the correct one for the 2004? Mine is an FX

 

found this.....
"Key will not program to 2009 F150. This is a 80 mhz key, I needed a 40 mhz key. Look for the "s" on the blade. These have the "SA""

 

The keys I had programmed are SA stamped keys. I don't think there's a way to ident the master without just reprogramming them both from scratch. If you bought a another clone, you could have a local shop or dealership wipe all of the keys from the PATS and reprogram them, then label whichever they made the master key.
