Thanks Dave, just dug my manual out.
It also says:
"If extra remote controls are requested in addition to the ones originally supplied, remember to carry out the same programming procedure for all the remote controls when the car is new.
The control unit will subsequently exclude this type of programming to prevent anyone else programming the control unit to 'acknowledge' another remote control.
If, therefore, you ever need a new remote control, go to your nearest Fiat Dealership taking with you the burgundy key, all the keys in your possession, plus the CODE card."
