Try to disconnect the car's battery to see if it will release the key.
Oh, if the car is dead then it won't release the key unless you cycle the ignition a couple of times with battery voltage. You will have to replace/recharge the battery or hook up another car as though you are going to jump start it and then turn the key back and forth a couple of times to reset the lock cylinder.
I think the lock cylinder is bad and will need to be replaced. The lock solenoid is stuck (killing the battery) and not locking/unlocking the key like it should.
Yeah, I would jump it and then have the ignition replaced. The more you mess with the key with no battery voltage the more likely you will be to damage the key or the ignition.
Let me know if you decide to tackle the ignition switch on your own. If you do, it will still need to be programmed with a scan tool.
It should unlock when it loses battery voltage, not lock. I think the lock solenoid in the ignition has a problem.
It might have jarred the lock pin loose at that point.
I hope you get it going again.
