I answered the magnets on the other thread...to open and close it and to program it, if you are good at loosing things order extra, I keep mine in a box with the battery, in a box next to the door. I love the door...I am getting a second one for the broody side. I followed the directions, including fully charging the battery on arrival before using it for anything. I use the solar panel so I don't mind if we loose power. It was easy to install with zero issues, the company is easy to talk with, and i just called to order it instead of on line...no problem.
