How do I get my key out of my 2004 chevy aveo?

Sounds like the ignition tumbler or the key is faulty. You can try to wiggle the shifter a little when in park or try wiggling the steering wheel a little too. It's possible you can get it out like this but ultimately this is going to require some disassembly and inspection. https://repairpal.com/repair-shops Alex

Spray bunches of WD-40 down into shifter cavity while moving shifting back and forth .. Key lock don't think shifter is in PARK.
