A while ago my wife brought both keys intonthe House and changed the battery. This lead to the keys not being synchronized and the remote lock/unlock not to work. I fiskes around with the synchronization procedure but was not able to get any of the keys to shnchronize. All I ended up with was that the spare key stopped turning in the ignition. Today I replaced the small unit on the rear hatch (looks like a old casette tape) and now I am able to synchronize and hav both keys locking and unlocking the car remote. The spare key will however still not turn the ignition. What can I do now? 2006 Supercharged
