A key comprises a key blade, a key handle integral with one end of the key blade and forming a portion of a carabiner that includes a generally C-shaped portion integral with said key blade, and a latching element having a first end pivotably attached to a first open end of the C to permit pivoting movement of said latching element between open and closed positions, and a second end overlapping the second open end of the C when said latching element is in said closed position, to limit the pivoting movement of the latching element. In one implementation, the key includes a biasing spring that urges said latching element toward said closed position.
