Sliding glass door keeper replacement

Hi, I am a landlord and my tenant told me that the sliding door keeper in the unit she is renting broke. As you can see in the photo, there is a chip on the bottom left of the center piece. I have tried to look for a replacement in various hardware stores in Hawaii, but none of them carry the part that I need. I was wondering if you folks happen to have it or something similar that will fit on the frame. Thank you for your help in advance!
