His part numbers match his key, but the data on our keys is different. I guess my question was, can the new key be programed to my car. It is advertized for 03-04 Boxster.
If this is a used key and he does not have the 24 digit code that goes with it then it is worthless as it cannot be reprogramed for any car. If he does not have the Porsche part number then it is a lost or defective used key.
