Key and Starting on 1998 Chevrolet Prizm

Have problem in the a.m. starting car. Up till this point it would take a jump. Cleaned the battery terminals but now the key won't turn and can't take the car out of park. I've tried putting the steering wheel in another positon but the key won't turn. Help!

REPLACE THE BATTERY! Your battery is dead. It won't allow the shift release to release the key and the shifter.
