Good news! You can re-use second hand keys
Ford Fiesta chips are re-programmable. This means that if you need a spare key for your car, you can re-use second hand keys. You should check you can find someone who’s prepared to programme a used key. Some companies won’t do this and will insist on supplying a brand new key.

If you’re looking for someone to programme it, just Google ‘car key programming’ or you can contact the companies that make equipment and they usually have a list of people in your area.
