Swivel key

Trying to match this swivel key. The only marking on it is the upside-down v shape in the zoomed in picture in the corner circle. This is from a storm door sliding glass section. The pieces you slide to raise the glass says Keller on it. The width is 3/32 the best I can tell and the height of the section that slide in the frame is 3/16. Total hight is almost 1.5 inches. It appears die cast. Thank you for your help. How long does it take for shipping to Fort Worth Texas and how much would it cost for the shipping? I'd like to order and get this as soon as possible trying to fix the door for my mother. I need the other side because the pin part is broken off. I think I should get both sides though.
