Searching for KK-1200-50

A quick learner says:
Good day,

My parents are trying to locate a storm door latch lock from an Emco Forever door. The part # is KK-1200-50. Can you help us please. My parents are in their 90's and feel insecure with this broken. The photos show the front and back to help you. Thank you

Best Regards

Hello, Keith. It's been a long time since I've seen this. I actually don't believe this is made anymore, but see our 40-043 set. I think this actually might be a newer version of your old make. Look over our pictures and information to determine if you could use this as a replacement.
