I tried the procedure that 02fordsvt suggested but it would not work. I could not get the horn to chirp to say it was entering the program mode.
The doors lock as soon as the key is in the run position, before starting. I am used to starting our cars in the winter to warm up, but this is the first car I have ever had that you have to unlock after starting. I'm just afraid she will lock them up more often than normal.
I just received 2 more blank keys in the mail today so I will have a few extras now.
Thanks for the help
