How can you fix a car door on a 1993 Dodge Caravan that will not shut?

On many vans/cars I have seen the latch on the door itself sometimes get tumbled into the shut position on accident. In most cases all you need is a screw driver to put into the latch hole on the door itself while pulling on the door handle simply flip the latch back open. If this is not the case please clarify your question.

The door jam has a male stiker the door latch is female or should be open to allow the striker to go inside it once the door is shut the latch wraps around the striker.
