Access to heaven

“Christ lives in karios time”
Close but no.

Actually right on the money.

Since Christ is not currently alive on earth AND
Since Christ currently exists in eternity
THEN Christ’s time is outside of earthly time (chronos) which is called kairos or God’s time.

Ad Majoram Dei Gloriam

Ephesians 2:4-7 But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus.

Born again believers, those who belong to God, are already seated with Christ in the heavenly places. Positionally, we are already there.

[Me] “Christ lives in karios time”
Close but no.
[You] Actually right on the money.

Jesus (if that is who you mean by Christ), God the Father and the Holy Spirit are not confined to one time "zone" as you state.

Since Christ is not currently alive on earth...

For Christians, within whom God dwells (ask for scripture and I will provide it for you,) Christ Jesus is alive, very much alive, here on earth. Inside every born again saved believer in Jesus. [Scripture reference available upon request]

Since Christ currently exists in eternity

God is omnipresent so that is one place He exists. Remember Jesus Christ=God=Holy Spirit.

THEN Christ’s time is outside of earthly time

Again, God is omnipresent.

kairos or God’s time

That leaves a lot our. Do a study on the word kairos.

Is God Omnipresent?
Correctly understood, the question of God’s omnipotence has historically caused little controversy. The term omnipresent, however, has caused more trouble. Basically, being omnipresent means being present everywhere at the same time. Can this term be applied to God? What does Scripture tell us?
Ask yourself: is there any physical location in this universe where we can hide from the presence of God? The answer, according to Scripture, is a resounding “No!” In fact, King David posed this question directly, asking: “Where can I go from Your Spirit? Or where can I flee from Your presence? If I ascend into heaven, You are there; if I make my bed in hell [the grave], behold, You are there. If I take the wings of the morning, and dwell in the uttermost parts of the sea, even there Your hand shall lead me, and Your right hand shall hold me” (Psalm 139:7–10).
David answers the question beautifully: it is futile to search for a place to hide from the presence of God (and it is unwise to try—just ask Jonah!). In this sense, God’s infallible word shows that He is omnipresent—within His vast creation, there is no place where you can hide from His presence.
Still, we must be careful with our terms! Many have tried to twist God’s omnipresence to portray Him as some kind of shapeless “blob”—even though the Bible clearly shows that God has a body and a shape—and it is a shape like ours! Consider Genesis 1:26, which tells us that man is made in God’s image and likeness—words that do convey a sense of shape. We do not use human philosophies to avoid the clear statements of Scripture! Consider, as well, the passage in which God says unambiguously that He has a face, a hand and a back (Exodus 33:18–23)! The only way to understand this passage from Exodus without making a mockery of God’s word is to agree that God has a shape and a body!
So, how is God “everywhere”? We already read the answer, in David’s words: “Where can I go from your Spirit?” (Psalm 139:7). It is by their Spirit that the Father and the glorified Christ have complete access to their creation! Through His Spirit, God’s reach extends to every nook and cranny of the universe, and there is—as David wrote—no place to flee from His presence. Yet He still retains a shape—a body—ruling in glory from His throne in heaven. It is from there that “His eyes behold” the sons of men (Psalm 11:4).
We must also note that although God is omnipresent through His Spirit, we can become separated from Him. In fact, we are warned, “your iniquities have separated you from your God; and your sins have hidden His face from you, so that He will not hear” (Isaiah 59:2). Jesus Christ experienced this horrible separation during His crucifixion, when on our behalf He took upon Himself the full penalty of our sins (cf. Mark 15:34; Isaiah 53:4–5).
The world’s scholars and theologians often have a wrong idea about God’s omnipresence. But if we let God’s flawless word teach us what God’s omnipresence truly means, our footing is made sure.

God is everywhere, in the known, and unknown universe. And the Spirit of God is infinite.

God cannot be put into a "time" box.

Look at it this way.

In the beginning, just before God created the heavens and earth, He was existing out side of time [because time didn't exist]. That's still his dwelling place but He may go wherever He wishes. And does.
