Well little update, tried removing the neg for 24 hrs then startng. Well that's also a no go. New tumbler will be here tomorrow. Also bought a code reader so I can see if something else is going on. Will keep this updated.

Alright guys, so the fix was the TUMBLR. I knew that when I ordered the switch it would be one or the other. So in my case the keys inside the actual lock cylinder just wore out to the point they would no longer work. So for anyone else with this problem, I would just order the two and replace them. Car was down almost 2 weeks and it really sucked. But after I pried the original one apart to get the key codes. Put the new springs and keys into the new one. Car tarted right up no problems. Hope this thread can help other people out in the future.

Good job

If you changed the ignition switch, you will have to reset the PCM and have the PCM setup the new Key, at that point you can program as many keys as you want.

You don't have to redo any keys as long as you re-key the new tumblr itself. Using my old keys just fine no problems.
