Isaiah 22:20 And it shall come to pass in that day, that I will call my servant Eliakim the son of Hilkiah:
22:21 And I will clothe him with thy robe, and strengthen him with thy girdle, and I will commit thy government into his hand: and he shall be a father to the inhabitants of Jerusalem, and to the house of Judah.
22:22 And the key of the house of David will I lay upon his shoulder; so he shall open, and none shall shut; and he shall shut, and none shall open.
22:23 And I will fasten him as a nail in a sure place; and he shall be for a glorious throne to his father's house.
A key speaks of authority or an ability to go where you want. This is a clear prophecy about Christ. He has all authority. Matthew 28:19-20
And the name Eliakim is H471 in Strong's concordance, it means "God of raising".
Yes, I agree. So that means Jesus is God of raising, and the portion of Yah.
