Help needed with Quattroporte Key

Can anyone help me with a spare key for Paulines Quattroporte. Truth is, don't ask!!! I messed her spare one up trying to change the case of it. Basically the circuit board is cream crackered in a massive way.
I have the case which is perfect but that is no good without a circuit board as it will undo the door lock manually but obviously will not start the car.
Can anyone suggest what to do (apart from the obvious go to the dealer and pay £200 plus).
If anyone has either a whole key including circuit board or just a circuit board on it's own then I would be delighted to pay good money for it.
Thanks in advance
Phil

The problem is its programmed to the key so you will still have to shell out for this dealer only service.

Think it's 200 big ones Phil!
