These houses had a magnetic key in the chimney that could open the house, turn on the lights and move the little people around on the floors. The key was about 5 inches long with a magnet on the tip. There were little walkways to connect the houses and make a village. You could slide the key under the walkways or floors to make the little dolls move around.
I had to update this answer. I searched ebay and they are called “Precious Places.”
