Saturn Repair Problems? Ask a Mechanic for Answers ASAP
This is a notorious problem with the Saturns and well documented. they had bad problems with the key tumblers. Most times the tumbler needs to be changed. Its the pins inside sticking holding the key from inserting. you can try a can of lock lube bought at most parts stores.. Insert the straw end and spry some in the tumbler. Benin inserting the key in/out and it may then free up and slide in. Also can try tapping the face of the tumbler where key goes in with small hammer or equal and sometimes frees up sticking pins. if not.. then the tumbler will have to be changed Very common problem,

Some customers may comment that the ignition lock cylinder intermittently sticks or binds.
A lack of lubrication may cause adjoining metal surfaces to wear, resulting in a significant amount of powder (black in color) to form in the ignition cylinder case housing.
