Can my dad legally take away my car even though he bought it for me but its under my name?

i pay for the insurance, car repair, gas....he just gave it to me 2 weeks ago and he made a copy of the key behind my back and he threatnes to take it away if i behave bad meaning if i use the car just for fun and no work or school..can he do that? the car is under my name ONLY im not affiliated with his insurance at all.
