VW Golf 5 Instrument Cluster Swap Issue

Hi to all friends.

I have a Golf MK5. Everything it is working well but the owner really wants to change:
OLD INSTRUMENT CLUSTER WITH NARROW SCREEN WITH NEW INSTRUMENT CLUSTER WITH WIDE SCREEN OF COURSE FROM A GOLF MK5.

Now I have PIN Code from ECU that I got by CarProg. When we start with new cluster the car starts and goes off.
Now, how can I match this cluster with car ECU to start the car?
As tool I have Carprog only. What transponder should be inside?

Thank you very much.
