Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
The Key code was attached to the original keys when the car was new, but now, if that is gone, the only place to get this code is from a GM dealer. They can use your VIN and proof of ownership to get your key code.
1998 saturn station wagon vin number is 1g8zj8278wz289897
I cannot get it nor can anyone on here, it MUST be done at a dealer parts counter for security issues.
If this was not the case, someone could take your VIN, look it up and get a key code then steal your vehicle.
