I am trying to find another handle/lock for my mothers sliding glass door. there is something broken inside of the latch and sometime when she shuts it, it will lock and then she is locked out. I am not sure what the door is, it came from patio enclosures when she had the sunroom addition completed. thanks for you help,

Thank you Sandy
