screw the 556u goto your local best buy and pick up a directed XK04 ford pats bypass if you need it because you dont need to lose a key.
YOu probably dont have one unless you have a theft ligh that flashes on your dash when your our of your car and you lock the doors. I did my uncles 05 FX4 and his didnt remote start didnt require a bypass unit. My 03 Edge did require it so it just matters what kind of key you have. If you have a basic silver key with no black ford thing on of the key you odnt have one. If you do have the black ford key then yes you do have an immobilizer
