Object.keys() as const not working. How can I achieve this? (Suppose I don't know the content of the object, I don't know what keys does my object have)

const values = Object.keys(myObject) as const;

I need the as const to get string literal types

let name: typeof values[number];

Reset to default 16

You can do

let name: keyof typeof myObject

See this question for why strongly typing Object.keys might be a bad idea.
