Same problem twice since September 17, 2013
Yesterday the car was running fine, stopped at work for a few minutes and when I got back in to start it up...it was dead. The key fob is locked in the centre console ignition and other that basic indicator lights there's no ignition ot start up. Charging it did not work, CAA tested the battery and it's low although it has some cranking amps left. This is a new battery 4 months ago however it's been very cold and I have not driven it other than for short trips for over a month now. With Saab's the battery doesn't have to be dead for the car not to start, it just has to be at a lower level than the car's electrical will accept. My hope is that the battery can be replaced under warranty or be fully charged. A new battery should fix you up fine.
