A few months back my car started being really stubborn about turning over. I'd have to rock the key (not the wheel) for nearly 5 minutes before it would start or let the key out. I saw a video where a guy suggested the wiring below the shifter so I replaced that and I still have this problem. Then I replaced the whole ignition with new tumblers and all. I still have the same problem.
Side note - while installing the new ignition I was putting the wiring clip (sits on top of the shell above the ignition) and I jammed the screw driver into it too hard and busted it. I have to replace that now too and I'm not ever sure what it's called.
I don't know what to do anymore. This problem is starting to become a money pit and I'm at my wits end.

What do I do to solve this issue so I can get my car back on the road?

I am attaching the testing needed for the B3055 which does appear to be the issue.

This means a key was used that is not programmed to this vehicle or the key is no longer programmed. However, when you add in the other codes, you most likely have an issue with the ECM or transponder itself.

Let's run through this testing and see what turns up and we can go from there. Thanks.

I've replaced starter two times and all my lights and everything coming on but it's still not cranking or even trying to crank. Battery is good, radio, lights are all on and strong but car not cranking or even making any noise to crank.

Good evening,

Did you verify power to the small wire on the starter with the key in the start position to see if you have power?

Okay, what was the result? Do you have power at the small wire in the start position?

If you have power, then the only thing left is the starter motor itself.
