Yale YRM276-ZW2-WHT HT Assure Lock for Andersen Patio Doors, WHITE (Tested Working powers on and goes into setup mode looks pretty new it has a micro tiny scuff or two as it wasn't packed the way it shipped originally but nothing that stands out see 2nd photo).. the larger of the 2 sockets on the back of the inside part the larger socket has a part of the plastic socket broken off the plug will still plug in and stay in but you have to be careful plugging it in not to bend pins the plastic part guides the plug into the socket being broke you have to guide it by hand  i believe its all there it doesn't look like the hardware packs were opened its more than likely a great deal for who ever purchases it.
