Leider hab ich in den Manual nichts aussagekräftiges gefunden:
"When a new vehicle is delivered, the dealer provides the
owner with a pair of identical keys and a bar-coded tag.
The bar-coded tag has a code on it that tells your dealer
or a qualified locksmith how to make extra keys. Keep
this tag in a safe place. If you lose your keys, you’ll be
able to have new ones made easily using this tag"
Deswegen die Frage ob jemand schon erfolgreich einen Schlüssel nachgemacht hat.
