I have a 04 Chrysler Sebring touring and I couldn't get my key out of the ignition which turned out was because park was not engaged but in trying to figure out why a light under my odometer lol lit up saying "done'........any idea what that is

 

In turning the key to the run position 3 times and leaving in the run position will activate the cars computer self test for OBD11 codes. If no problems exist, then the "word" dONE appears on the dash(odometer location). We MOPAR DIY'ers call this the "key dance".
Congrats. you have no problems in what the car's computer and engine/trans sensors work to make your car operate.
