key stuck in ignition, can i jump start it?

i've got a problem with my shifter, and my key is currently stuck in my ignition.  my mechanic told me to turn off everything i could, because my car is still partially on, just on accessory, but he said it would not run my battery down over night.  turns out, i ended up not using the car at all today, and forgot to start it up to keep the battery alive.  i remembered tonight about 10pm, about 21 hours after i'd last used it, and it was dead.  since it's still partially on, i'm scared to jump it, as i do not want to mess it up any further than it is now.  does anyone know if it's okay to jump a cobalt if the key is not turned fully off?

Your shift lock is out.  Mine has done the same thing.  There is a small access panel under your stearing column.  You remove the lil plate and stick your finger up and hit a plunger in the column.  Your key will turn to the the unlock position and you can remove your key.  I would not jump the car with the accessory lock on.  I dont know how to fix it i am posting a request to fix also because i have been having this same problem for a few months.

It will be ok to jump with key stuck in ignition, the problem why your key is stuck is the shifter assembly. It will need to be replaced.
