Storm door replacement lock

Question

There are no markings on the lock. The spring is broken on the lock. when I turn the key, the bolt doesn't grab onto the socket and the key turns all the way around. I'm hoping you have this type of lock. Thank you Elizabeth

Hey, Elizabeth. I recommend looking at our 40-194 to start out. This appear similar to the part in your pictures, though you will need to carefully go over our measurements to confirm that they line up.
