Door lever for storm door made by Sugarcreek industries

The inside door lever nit longer latches. I attached a photo of the lever. I do not know if it is necessary to also replace the outside lever. I also attached that photo.

Good day,
Previously I submitted a post - reference D304669

I was seeking info on my inside storm door lever which no longer closes/latches. I attempted to attach photos that I left out but my submission was tagged as spam. I am attaching the photos that did not accompany my post.

screws - approximately 1.75-2" apart
inside lever- 1.25"x 1"
outside curved handle - 4.25" x 1.25

I wanted to know if it is necessary to replace the inside lever and outside handle together - in order to restore the spring action of the inside lever.

Thank you
