If Ford can remove the lock to get the code (something I know they can do as I used to do it), why drill one out in the first place?.
Is the car double locked?, if not, they are fairly easy to get into with a coat hangar through the door.
I'm also pretty sure that Ford can get your key code from the vin number, this would mean they could cut a key without messing with the locks.
Have a look in your service pack, they originally came with 2 plastic strips that were attached to the keys when new, if these are still in the pack, they have a 6 digit number on, this is your key code. You can cut a key with this then program it later.
