Ignition is locked

I have a 2000 Saab convertible. The gear shift is stuck in park. When I put the key into the ignition I can get nothing to move. Are there things I can try to solve the problem?

The voltage from the battery may be too low. Check the battery voltage, or connect a jumper battery (using jumper cables) to your battery. Then, try it.
If no luck, come on back, here.
