I had a problem in as far as I could not start the car as the fault code read key not detected upon further investigation it was found that a devise plugged into the 12v socket to give two extro 12v outlets plus a usb and battery monitoring system from a local high street shop is interfering with the key detection. has anyone else had this problem on their s-max or any other Ford

A regular situation on my Mondeo Titanium X with power start.
Usually occurs when unusual door opening/closing detected.

Mine will however start when key fob inside car and clutch depressed.

Try again
