I just noticed car starts and shuts off without a key

Do I swap out the whole ignition?
Which one do I get?
Where do I begin with this one?

If you mean you can turn the lock cylinder on the steering column without the key in it, you should just need to replace the lock cylinder.

Yes that's exactly what I meant. Thank you so much for your quick response...
