Abstract A key or wrench for turning sprinkler valve handles has a body formed at the top with a socket in the shape of a hollow Greek cross complementary to the conventional valve handle. Below the socket is a thin-walled annular skirt dimensioned to fit within the tube usually surrounding the valve. Internal, rounded protuberances in the skirt guide the valve handle into the socket. The key has an elongated handle twisted to facilitate turning the key and the valve handle seated in the socket thereof.
