Sliding Glass Door Replacement Handle with interior latch or keyless locking mechanism

I have an older sliding glass door and I can not find a replacement at Home Depot. The space between the screw holes on my current handle is 5", the others I found are 4". Looking for a replacement plus the outside pull. I do not want a key lock. I do not know the manufacturer, and most likely the sliding glass door is original, my home was built in '91. Thank you.
