Re: new keyfob
Had a similar issue this weekend.
Bought mine with one ley, but had the Code Card in the handbook wallet.
Took it to a Auto Locksmiths they plugged in the diagnostic/coding unit and fouind out the code doesn't work for my car.
Oddly enough the card also has a mechanical code, which is the way the actual key must be cut, this does match the physical profile of the key for the door/boot/ignition.
That means that half the infomation on the card is correct, the other half is not. Perhaps at some point the car's had a new alarm/immobiliser ECU and keys coded to it.
So, how do I get a new key for the car? Who will know the ECU codes?
