Hi all. I have a 51 ford focus zetec mk1 and for the past 3 years my 3 button remote key has not worked. I think this has also effected the central locking, but that's another topic! Anyway I went to ford today and they said I need a whole new key, as its pretty worn out, and it will obviously need re-programming. New key they want 70 and re-programming they want 90! I know that u can programme it urself, but question 1, does this actually work and question 2, will it work on a whole new key?

Thanks all
