You can try getting the serial number by pressing buttons #1 and ~#6 together (sometimes #2 and #6 works), then scrolling down or wait until the serial number is displayed.

The serial number will begin with a "V" or an "M", followed by a six-digit number. So it will be in the form of V123456 or M123456.

Then, having obtained the serial number:

1. For radios whose Serial Number begins with an "M", followed by a six digit number, you can use the following link to work out what your Keycode should be:

2. For radios whose Serial Number begins with a "V", followed by a six digit number, I'm afraid there is no Keycode generator available for you to work out the code yourself.

You will either need to visit your local Ford Main Dealer, or there are sellers on Ebay who claim they can supply the Keycodes for "V" Serial Numbers, for a fee.
