Flip key for an automotive vehicle with enhanced resistance to forces exerted onto an insert of such flip key

An automotive vehicle key comprising:

• an insert for being introduced into a lock of a vehicle;
• a bearing supporting the insert;
• a housing wherein the bearing is mounted in the housing in a rotatable manner so that the insert and the rotatable bearing can rotate between an open position in which the insert extends outside the housing and a closed position in which the insert extends internally in the housing;
• and
• a button extending inside the rotatable bearing, the button comprising at least two anchoring legs,
• the rotatable bearing comprising two anchoring cavities and the housing comprising two anchoring cavities,
• the anchoring cavities of the rotatable bearing and of the housing being arranged so that each one of the two legs gets anchored simultaneously into both an anchoring cavity of the housing and an anchoring cavity of the rotatable bearing so that the button maintains by the two legs the rotatable bearing and the housing fixed in mutual rotation at least in a situation where the key is in open position, the rotatable bearing presenting an elongated shape so that the rotatable bearing presents at least a longer dimension (a) and at least a shorter dimension (b) transversal to the at least one longer dimension (a),
• wherein one leg of the at least two legs extends sensibly in the direction of the longer dimension (a) and the other leg (32) of the at least two legs extends sensibly in the direction of the shorter transversal dimension (b), and the leg extending in the direction of the longer dimension (a) is longer along said longer direction (a) than the leg which extends in the direction of the transversal dimension (b).
