Hi

I believe that only four keys can be programmed at any one time for a ford. I have just got a new key and programmed it. This seems to erase the other key from the system ( doors, not immobiliser). If I then reprogram the original key then the new one gets deleted.

This suggests that a previous owner has programmed additional keys over the years and the four key limit has been reached.

Does anyone know how to delete all keys so that I can start again. The car is a 2003 streetka.

thanks
