Thanks for using Just Answer. I would be glad to assist you.
When you purchased the vehicle you should have been given the security code. It is usually on a business size card with your owners manual or other papers in your glovebox.
If you cannot find the code, then you will need to remove the radio. There is a serial number on the back of the radio that you can use to find the security code. Just call Saturn with your VIN # and the serial number off of the radio and they will supply you with the code.
Please let me know if there is anything else I can do to assist you.
