Claim:
A module for deploying a retractable insert of a key for a motor vehicle, the module configured to be mounted in a casing of said key, and comprising: an insert configured to be pivot-mounted with respect to said casing between a rest position in which the insert is retracted inside said casing and a position of use in which the insert is deployed with respect to said casing, the insert comprising a key bit and a key bit support secured to the key bit and pivot-mounted with respect to said casing; and an insert deployment mechanism comprising a push button and an elastic return element for returning the insert, the elastic return element comprising a helical torsion spring, wherein a first end of the elastic return element 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 at least one guide peg that blocks the rotation of the push button with respect to said casing, and forms a guide for the push button in axial translation, wherein said elastic return element is fixed to said push button by a second end, wherein the first end of said elastic return element is fixed to the key bit support so that said elastic return element urges said support to pivot to deploy the key bit when the push button is actuated, wherein said push button comprises a retaining projection for keeping the insert in the rest position and in the position of use, a position for mounting the retaining projection being different than said rest position and position of use, and wherein said key bit support comprises a collar with an opening through which said retaining projection passes in the mounting position, wherein the collar is recessed below the key bit support.
