FROM OUR CATHOLIC CATECHISM
553 Jesus entrusted a specific authority to Peter: “I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” The “power of the keys” designates authority to govern the house of God, which is the Church. Jesus, the Good Shepherd, confirmed this mandate after his Resurrection: “Feed my sheep.” The power to “bind and loose” connotes the authority to absolve sins, to pronounce doctrinal judgments, and to make disciplinary decisions in the Church. Jesus entrusted this authority to the Church through the ministry of the apostles and in particular through the ministry of Peter, the only one to whom he specifically entrusted the keys of the kingdom
936 The Lord made St. Peter the visible foundation of his Church. He entrusted the keys of the Church to him. The bishop of the Church of Rome, successor to St. Peter, is “head of the college of bishops, the Vicar of Christ and Pastor of the universal Church on earth” (CIC, can. 331). [Code on Canon Law]
881 The Lord made Simon alone, whom he named Peter, the “rock” of his Church. He gave him the keys of his Church and instituted him shepherd of the whole flock. “The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head.” This pastoral office of Peter and the other apostles belongs to the Church’s very foundation and is continued by the bishops under the primacy of the Pope.
979 In this battle against our inclination towards evil, who could be brave and watchful enough to escape every wound of sin? “If the Church has the power to forgive sins, then Baptism cannot be her only means of using the keys of the Kingdom of heaven received from Jesus Christ. The Church must be able to forgive all penitents their offenses, even if they should sin until the last moment of their lives.”
981 After his Resurrection, Christ sent his apostles “so that repentance and forgiveness of sins should be preached in his name to all nations.” The apostles and their successors carry out this “ministry of reconciliation,” not only by announcing to men God’s forgiveness merited for us by Christ, and calling them to conversion and faith; but also by communicating to them the forgiveness of sins in Baptism, and reconciling them with God and with the Church through the power of the keys, received from Christ:
[The Church] has received the keys of the Kingdom of heaven so that, in her, sins may be forgiven through Christ’s blood and the Holy Spirit’s action. In this Church, the soul dead through sin comes back to life in order to live with Christ, whose grace has saved us.
So YES

The Catechism has much to share on the issue of "[ALL] of the Key’s
