Hey mustangpony69,
No the 555F won't work. You need a 555U or any other bypass that requires a key. This vehicle is equipped with a CRYPTO factory immobilizer.

or if you dont want to give up a key buy a blank ford crypto key have it cut and and you program it in a matter of seconds, Now you have a new key for the car!! If you go this route I can tell u how to program the key ! YOu dont need any computers or tools for this just the blank key., when buying the blank key make sure it i sthe one with a blue bubbled out ford symbol,it should look exactly like the key you use now! cost should be like 18 bucks for the key tehn you will need a 555 u or youy can build your own for maybe 1 dollar! posted_image

well what you need to do is have 2 keys that already start the car .

Then you will take the first key by itself and put in ignition turn igniton on wait till security light goes out now quickly get the second key and do the same thing,Now take that key out and do the same thing with new blank key wait till light goes out turn ignition off .The new key should be programed now it should start the car .

programing has change a bit from earlier years now you have less time to cycle the keys in the ignition posted_image

!

So have your keys within reach and ready take any keychains off the key so that it is only the key (no remote keyfobs)on the chain.

Let me clarify my directions sorry ,

Put the first working key in the ignition turn it to run and back off ,take the second key and do the same thing turn to run and then back off.
Now take the new key turn to run leave in for 1 second turn off now it is programed.

or you could go to bypasskit.com , they have an encrypted key bypass, if it's not on the site, call them, they definitely have it.
