Yesterday I went to start my car and the key just turns from right to left freely. It doesn’t trigger my starter or anything else. I was thinking ignition cylinder replacement, but the one I bought, which is for my car, is way too small. I don’t know much about cars and hope someone has an idea. Thanks so much

 

could be the cylinder or the housing

 

I was thinking it was maybe the cylinder so I bought a replacement. I made sure it was the right part and the damn thing is much smaller. I’m still trying to replace it to see
