The more you use your key, the more the key will wear down overtime. Eventually (especially with car keys) the key will not match up to your tumblers in the lock, and will intermittently not work, and eventually not turn at all. Do you have a spare? if so use it see if it works, then have a copy made. If you don't, call the dealership, have them make you another key, or call a locksmith.

Now if the key won't come out of the ignition, that's a whole other issue, but it doesn't sound like this is the case. Hope this helps you out, good luck!

You could try tapping the starter and/or having it checked by a mechanic. If the vehicle is starting once in a while, have a mechanic check the Crank Shaft Position Sensor located on the Intake Manifold under an aluminum bracket. The wire to the sensor leads towards the throttle body. the connector at the throttle body is blue. This sensor is notorious for giving out gradually. If this is the problem, seriously replace it as the vehicle could die when driving (i've heard, but don't quote me on that). I owned a 2001 9-3 turbo and the same thing would happen until it no longer cranked. I replaced it when i researched the issue on the internet. The car turned on as soon as i replaced it 8) and did not have the same problem again.

Good luck!

Thanks for returning and placing your comments. This "jiggled the key while held the shifter all the way back released!" quickly solved my problem today. Otherwise I was in panic how to move my parked car out of restricted street cleaning side. You should add this to saabsite forum. Saab 9-3, 2002
