Sillcocks generally have the valve shaft recessed so that you cannot use a gripper type tool (visegrips) on it. The sillcock key has a "socket wrench" type end on it. Sillcocks on commercial buildings are designed to prevent vandalism by being operable only with a sillcock key, not a ratchet & socket. I will be getting a 4 way key. Thanks for bringing this to my attention.
