You need to take that up with the Christ who gave Peter (the man) the keys to the kingdom of heaven.
By your interpretation of Scripture don’t forget after your famous verse about the rock three versus later Christ called Peter Satan you might want to do some more reading The only one who holds the keys to the kingdom is Christ himself
And THE BIBLE shows clearly that Peter used those keys to open the New Covenant doorway to Jews and Gentiles, albeit he had to have a nudge or two to go to the house of Cornelius. Peter loosed the entry to Heaven and bound the doorway to the following law of sin and death which Jesus covered with His perfect blood.
Christ gave us all the keys to heaven, HIMSELF
