Cleaned out the ISM twice. Even tried scratching up the surface of the contacts with a file, still no luck. I ended up with another issue, with the Steering Wheel Malfunction.
Purchased a new ISM from NAPA Auto Parts, about $115. Everything works great. No issues and my key fob finally locks and unlocks. Thanks for this thread.
