It’s 042
1-from the first two hints you understand that 6 is definitely not in the key
2-from the third one you understand 2 and 0 is in the key but not in that order (as it cannot be 6)
3-when you look at the fourth one it is clear 8 is not in the key so in the first hint only the 2 can be the key and it is in the right place. (Now that you know 2’s position, you can look at the third hint and understand that 0 is in the first as the last place is taken and middle is incorrect  – so from this point on you actually don’t need the fourth and fifth hints.
4- fourth hint gives you 7-3-8 are not in the key so from the fifth hint you can understand 0 is in the wrong place and looking back at the third hint 0 should be first and 2 should be last
