for safety reasons, only a dealer can get your key code from Ford and make you a key. You will need proof of ownership and your VIN number and ID. 1-800-241-3673.
You can try calling Ford Roadside Assistance. They may be abe to help.

Sometimes, you can take a long, thin screwdriver and lift up the door handle. Slide the screwdriver in the slot under the handle. Move around till you see the lock button move and try to pry it up. Also, local police might help with a slim jim.

If you open trunk and look on inside of trunk where hinge bolts are you will see code numbers . Owners manual will tell you how.

Take the plastic cover off of where the jack / wheel wrench is located on the rear left side. Standing in the back of the vehicle, look forward (toward the steering wheel) and you will see a computer module. The factory code is typed on that module. You might have to "carefully" pry the plastic out and do some mild acrobatics to see the code, but that is where it is. After you find the code, go to your owners manual and reset the code to your own numbers. You will have to do this every time the battery is disconnected, so you might want to just remember the factory code. Good Luck

If you have the Keys to the vehicle you can get in. Giving that code out will put other vehicle at risk. If you have a manual it will have the reset code in it. Try using the manual first if that does not work go the dealership.
