A self-ejecting key device for drill chucks has a main body with a handle, a key element and a forward guide pin with a groove along one side for retaining a slidable ejector member. The groove is aligned with a bore that extends through the key element and main body. Retained within the bore is a coiled spring which is secured to a slidable ejector pin in the groove that projects outwardly from the side of the guide pin.
