Hi Linda! It sounds like you are having electrical issues with your car. I would recommend if you can, have it towed to the nearest reputable repair shop or Ford Dealer. Because of the Security System with the car, after the batter is disconnected or removed the car needs to be recoded for the Starter, Master Computer (ECM), and keys to work. The Ford dealer should recode this at no cost to you. I hope this helps! Best of Luck!

This is a problem that is becoming more and more a problem, when the battery is disconnected or replaced. They make a little tool that you can plug into the power port that maintains the vehicles presets that the factory and the owner have programmed in, a must have in your tool box, there are now 2 styles 1 plugs into the power ports the other plugs into the OBD port itself. Yes Sixfoot car guy is correct you will have to return to the dealer to get it reprogrammed to your VIN.
