Car attempting to start, no key in ignition .

What is your question?

My 2000 olds has been trying to start with no key in the ignition, I though it was starter but replaced that- and still trying to start with no key in ignition. Only to stop is thus far is to either disconnect positive cable, or crank it and then take the crank fuse out after starting it up. Otherwise it would just knock and shake.no lights come on for check engine or anything g.
