Can you still reach ketosis if you don't meet fat goals?

I've been trying the keto diet for five days now and have kept my carbs under 20g every day. I usually hit my protein goal too. But I have a hard time getting as much fat as my goal says.

Would I still reach ketosis if I eat the right things and keep carbs under 20g or do I absolutely have to eat all my fats for it to work?
