 bought my car used and only have one key.  I was trying to reset some settings after an oil and tire change and accidently set my one and only key to the mykey feature. You have to have another key to act as an admin key when this happens to get the setting changed back. So now...I have to spend a ridiculous amount of money to replace and program another key just to remove this very stupid feature. It limits your speed, it limits the volume on your radio among other very, very annoying features. What would have been wrong with having to set a password like every other computer program on the planet....no, leave it to ford to have to make something so dumb an expensive fix.....HIGHLY DISAPOINTED WITH THE GENIUSES THAT CAME UP WITH THIS!!!!!!!!!!!!!!!
