$40 bucks later I have 5 new keys and have discovered how this all happened. The people/person living here before us replaced a few of he bulbs under the cabinet with the wrong size. They were too large and were putting out too much heat and too much stress against the covers. Those two mistakes lead to my Mmmmeling Macbook Pro.
Lesson to be learned? When buying an old house make sure to check your under the cabinet lights!
