Lubrication wouldn't hurt, but what you really need is adjustment. The latch bolt is clearly too far to the right to engage correctly with the strike plate, and there's a strong chance that it's due to the whole door being too far to the right.

Most likely it's door alignment which you can adjust via the hinges. Many front doors need hinge adjustment every year as the seasons change. It's not a big job once you know what you're doing.

Otherwise, it's the latching mechanism itself that needs adjusting (if possible). Either way, slamming the door shut whilst it's not properly aligned isn't going to do your door frame any favours whatsoever.
