My key turns my car on but won't let me pull it out of the ignition when in park and turned off

What is your question?

I can turn my key in the ignition and start my car ,but when I put it in park and turn it off it won't let me pull the key out of ignition. It drained my battery so I replaced it , then replaced my alternator but it still won't come out . The key no longer has the push buttons working on the top. However it's been working manually could that be the issue. Someone suggest it's my gear shifter. That it's not going completely into park . Please help.. I'm a single female not knowing what to do. Thank you ..Frances 213 3226862
