The invention relates to an automotive vehicule key in which a button (30) maintains by means of two legs (32, 33) a rotatable bearing (20) and a housing (40) fixed in mutual rotation at least in a situation where the key is in open position, the rotatable bearing (20) presenting an elongated shape so that the rotatable bearing (20) presents at least a longer dimension (a) and at least a shorter dimension (b) transversal to the said at least one longer dimension (a), wherein one leg (33) of the said at least two legs (32, 33) extends sensibly in the direction of the longer dimension (a) and the other leg (32) of the at least two legs (32,33) extends sensibly in the direction of the shorter transversal dimension (b), and the leg (33) extending in the direction of the longer dimension (a) is longer along said longer direction (a) than the leg (32) which extends in the direction of the transversal dimension (b).
