Ignition can't be blocked by onstar. Is it just a no start? An 03 should not have a functional onstar, unless it has been upgraded from analog to digital. There was a special coverage adjustment to warranty to deactivate it, but that expired in 2008. Is there an LED illuminated on the mirror(either red or green)? Here is a copy of that bulletin information.

The service procedure in this bulletin has been revised. Step 11 in the procedure for the 2004-2005 Saab 9-3 (9440) Convertible has been revised. Discard all copies of bulletin 08089B, issued September 2008.
--------------------------------------------------------------------------------
Condition
In November 2002, the U.S. Federal Communications Commission (FCC) ruled that wireless carriers would no longer be required to support the analog wireless network beginning in 2008. As a result, On Star® is unable to continue analog service.
OnStar® has deactivated most of the systems operating in the analog mode; however, there are some vehicles that OnStar® could not deactivate. Although the analog OnStar® hardware in these vehicles can no longer communicate with OnStar®, the hardware in the vehicle is still active. If the OnStar® emergency button is pressed, or in the case of an airbag deployment, or near deployment, the customer may hear a recording that OnStar® is being contacted. However, since analog service is no longer available, the call will not connect to OnStar®. To end the call, the customer must press the white phone or white dot button. If the call is not ended, the system will continue to try to connect to OnStar® until the vehicle battery is drained.
Special Policy Adjustment
At the customer’s request, dealers are to deactivate the OnStar® system. The service will be made at no charge to the customer.
This special coverage covers the condition described above until December 31, 2008 for all non-Saab vehicles; April 30, 2009 for all Saab vehicles.
