Multiecuscan

I have a Grande Punto '06 with one normal key and one key with remote for central lock. I'd like to have one more key with remote control, so I have a question - does the key coding procedure adds both the immobiliser and remote or only the immobiliser? If only the IMMO is added, then how to add a new remote?
Another question - is it possible to add a key/remote, which was previously assigned to another car? Finally - if I'd like to add a new key, I have to encode a total of 3 keys - 2 old, and 1 new, yes?

I think on a Grande you can do all together - key storage and remote storage at the same time.
On other models you can do separately key storage and remote storage (depends from a model).
Yes you can add remote from other car to your car...
You can add maximum of 8 keys...
