I couldn't move THEKEY coin from my O3 wallet. Please help me.

I made a Neo wallet a few years ago and put in THEKEY coin.

But recently, I opened my wallet and there is no THEKEY coin.

So I looked around and found out that I should have moved the coin to another wallet.

I couldn’t move the coin at the time.
I want to transfer THEKEY coin from wallet to another wallet now.
Please teach me the way

Hi SeonG, could you elaborate more on this issue?
