One person exerts more force than the other so that the forces are unbalanced.

Explanation: Motion occurs only when the net force is not zero. If the two forces are equal and opposite (balanced), their net force is zero and the door won't accelerate. If one person pushes harder, the net force is nonzero and the door will move.
