Claim:
A key for a motor vehicle, comprising: a casing with an upper half shell forming a lid and a lower half shell forming the casing bottom; an insert mounted to pivot with respect to said casing between a rest position in which the insert is retracted or stowed in said casing and a position of use in which the insert is deployed out of said casing; a mechanism for deploying the insert which is mounted in said casing, wherein the mechanism comprises: a push button housed axially in an associated housing of the upper half shell and projecting with respect to the upper half shell to be actuated by a user, and an elastic return element for returning the insert, a first end of which is connected to the insert to urge the insert to pivot toward said position of use when the push button is actuated, wherein the push button comprises a means for blocking the rotation of the push button with respect to said casing that forms a guide for the push button in axial translation, and wherein said elastic return element is fixed to the push button by a second end, wherein said guide forming blocking means comprises at least one guide lug that guides the push button and collaborates with a corresponding slot of said housing of said upper half shell, wherein said guide forming blocking means enables said push button to be non-rotatable with respect to said housing.
