My wife's 2005 f150 has been having problems she puts the key in the ignition and it turns over. she does it again and it doesn't. we had the batter checked it is fine. The ford dealer has it now and they can not figure out why it turns over then it doesn't. We have two sets of keys one will work and the other won't and then the other will work and the first one will not.
Has anyone had this happen before.
