I only had one key when I bought my mondy 99 (V) reg Ghia X auto , the only solution as above is to take the car to Ford. They charged me over £100 just to have a normal key made ( not a remote control key) and said it was because I had not got the red key.
It is ESSENTIAL when buying a used Ford that you obtain the RED master key otherwise you will be in for a LARGE bill when it comes to getting spares!
