Your Saturn has "PassLock 2"
The passlock system is designed to prevent vehicle operation if the mechanical key is not used to start the vehicle.

The mechanical key, in normal operation, will turn the passlock lock cylinder.

The passlock sensor (which is mounted to the passlock lock cylinder assembly) sends data to the BCM & the PCM to start & Run
IF you have removed the Cylinder, you will not be able to keep the engine running
Once you Replace the Key Cylinder, you will have to PROGRAM the PassLock 2 to the New Cylinder, so be sure you get procedures from Parts Store that you get the Cylinder from
