Thank you for using just answer.
I am sorry to say but you cannot bypass this system or permanently disable.
What have you replaced to fix the system?
Have you tried another key?
I have not heard of a bypass kit and me personally i wouldnt do that.
The way the system works is the keys and the ignition cylinder transcevier.If both your
keys are messing up its possible that the transcevier is messing up or the keys are
getting weak.These are both easy fixes but you cannot do it.You will have to take to ford
dealer for reprogram.
