I have a 2003 Saab 9-3 Arc. I recently just replaced the alternator. I charged up the battery and installed it and the car was up and running fine. A few days passed not driving it because of a snow storm and when I finally went to go start it, the key would not turn in the ignition. The steering wheel is also unlocked...so no clicking when the key is inserted. I found out I had a bad battery after testing it with a voltmeter after a full charge..it drained really quickly. I just got a new battery today thinking it would solve the problem, but my key still won't turn. I've tried taking the neg cable off for a while and trying again and no luck. I've kept the key in for 10 seconds..took it out...then put it back in and no luck. I tried the spare and that didn't work. And I've also turned the key 180 degrees multiple times. Nothing is working....what do I do?
