Hey...i purchased a 2nd hand 3 button passat fob key(which has the correct code on inside of the key) with a blank uncut blade which is ready for cutting......
i was looking for instructions on programming the key and i saw the link below but this is for an A4;
is a passat done the same way or is there different instructions for a passat??from reading the instrutions it seems i might be able to do it myself??!!(possibly)

after programming it,will the new key work with the immobilisier and do everything my orginal key is doing,3 buttons working or is there further work necessary?

thanks for yer help
