Need exterior door lock help, talk to me like I am an idiot

My exterior doors have a cool looking lock mechanism, however, the latch part has nothing to grab hold of. I called Sams marine, and they sent me some strike plates. However, on the strike plate side, there is a metal channel that has nothing to do with strike plates. I tried to make a few pieces to get into the metal challel to attack the strike plate but it has to be positioned just right because the latch has a small field of travel. Anyone solved this problem?

It locks the handle internally. Not a deadbolt.

Sam's can get the key, I'm waiting on one now.

You’re missing the strike plate. Photo below. Sams has them under door locks.
