The Keys are and were an ancient symbol or authority that any knowledgeable Jew would have recognized for what it was. To claim that the keys represent some sort of symbolic key to understanding Scripture is be ignorant of history and Scripture itself. Besides, if the key's did hold some sort of Bible interpretive power, you will note that Peter and ONLY peter was given the Keys.

[Tao Yin]

If the keys given to Peter were so important, then why were they only mentioned in 1 out of the 3 tellings of the story?

The point is that the keys were not the point of the story.

The keys do give me pause, but not enough to believe in secret teachings or evolutionary theology.
