In Christian tradition, St. Peter is often depicted holding keys as a symbol of his role as the keeper of the keys to heaven. This imagery is based on a passage in The Bible where Jesus gives Peter the keys to the kingdom of heaven, granting him the authority to govern the church on earth.
The keys are indiciative of St Peter.
The keys to the Kingdom of Heaven.
St Peter is usually depicted holding keys (the keys of heaven). Or, sometimes he is depicted being crucified upside down (as it seems to have been St Peter's wishes when he too was crucified).
Peter, the first pope, is usually represented by two keys - the keys to the kingdom of heaven symbolically given to him by Christ.

Patrick is not the one shown with the keys. It is St. Peter, the Apostle. When Our Lord appointed him as leader of His Church He told Peter, "I will give to you the keys of the Kingdom of heaven."
The Pope holds the "Keys to the Kingdom of Heaven" according to scripture. These "keys" were first given to St. Peter by Jesus Christ (Matthew 16:15-19). It is the understanding of the Church that these keys are then passed on to his Successors in his post as head of the Church.

This power was given to St. Peter to symbolize the authority he would have to access the kingdom of heaven.
The name is attributed to the belief that just as St Peter holds the keys to heaven
St. Peter was the first pope. There is a symbolic proof in the Bible when Jesus gave Peter the keys to the kingdom of heaven and when He said "Peter you are the rock and up on this rock I will build my church."
