The verse you are referring to is in Matthew 16:19, which reads "And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
Jesus entrusted the keys of the kingdom to Simon Peter, as described in the Bible in the Gospel of Matthew 16:19. He referred to Peter as the "rock" on which he would build his church, giving him the authority to bind and loose on earth and in heaven.
In Matthew 16:17-19, Jesus said to Simon Peter, "Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven." Jesus was affirming Peter's faith and declaring him as the foundation of the church. The "keys of the kingdom of heaven" symbolize Peter's authority and leadership in spreading the message of Jesus and guiding the early Christian community.
Peter was symbolically given the keys to the Kingdom of Heaven by Jesus.
Peter
St. Peter is given the "keys to the kingdom of Heaven" by Jesus, which symbolizes his authority as the leader of the Christian church. This is referenced in the Bible in the Gospel of Matthew 16:18-19.
In Matthew 16: 18-19 Our Lord appoints Peter as the head of the Church:"I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it. I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven."This is the origin of Saint Peter traditionally illustrated holding keys.

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 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.

Jesus says to St. Peter--19 "I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven." --Matthew 16:19 New American Standard Bible
That originated when Jesus Christ himself said that, "Blessed are you, Simon Barionah (Peter son of Jonah). For flesh and blood has not revealed this to your, but my heavenly Father....I will give you the KEYS TO THE KINGDOM OF HEAVEN...."You can find the verses above on chapter 16 from the Gospel according to Matthew in the Holy Bible. The verses quoted above is from verse 17 and 19Answer Peter is also known as "The Rock of Christianity" and he is the leader of the Christian Church.
No, he gave symbolically the Keys to the Kingdom of heaven to Simon Peter, not to Mark.
