I just recently got my saab back from the shop where they installed a new battery. this reset all of the electrical components in my car, including the stereo security system. i accidentally entered the wrong code to start it up again and now it thinks it's being stolen and just keeps beeping. i know the right code and i'd like to enter it, but i don't know how to reset it so that i can enter the correct one. help me! i need music when i drive!
