Buick century ignition problems.

Hi, yesterday my key got stuck in the ignition in my 2001 Buick century.
and I couldnt pull it out. I played around with it for a few minutes. I pulled on it really hard and the key wouldnt come out. After a while i got the key to come out but not that easily. After that I could turn on the car without a key and I thought I broke the ignition. I put the key back in and turned on the car and the security light went on,on the dash board. So ...for some dumb ass reason i got the iea to drive it around in the neighborhood. I got about 300 ft. from my house when the light was still on so i turned off the car. When I did that the key pulled out easy but, when I went to put back in the key the ignition would not turn . It feels like there is no key in there because the ignition starts to turn ...or can be wiggled back and forth.Ya..so...my car is in the middle of the road in my neighborhood, and I'd like to know what you think is wrong and how I can fix it. If I wasn't clear please ask about specific parts of the story.

Likely a new lock cylinder is required. AAA or a locksmith can install it for you right where the car is. They usually do this for recovered stolen cars or when the ignition is really old and worn out.
The last time I had it done cost $100 installed.
