It's a 3 position rocker switch that returns to center. Rock up is open rock down is closed. I first thought the only way to really make it work would be a key pad and an external rocker where the keypad locks or provides power to the external rocker, but there might be something on the market that has an open and close button on it. If push comes to shove and i have to put a key fob remote in place of the external keypad i can live with that. It sounds like it may be the easier of the options where unlock on the fob sends the open signal and lock sends the close signal. The fob would probably have a trunk and/or an alarm function and i could wire the trunk to activate our heater.
