There is a wooden stool with a horizontal bar next to the bus stop in the fourth district of Yangshan, Suzhou. My key fell into a gap in the board. The gap is not big enough for the naked eye to see inside. Usually, the copper-aluminum key magnet is invalid, because the seam under the wood strip is large and the seam on the top is small, so it is difficult to take it out directly. If there is a seam on both sides, you can pull it directly to one end and take it out. It doesn't matter if both sides are slit seamlessly. If the screw handle is closed on the iron seat, use a wrench and pliers to remove a piece of wood and take out the key and put it back.
