Abstract

The invention relates to a key (21), in particular an emergency key, comprising: a head (23) comprising a cavity (39) that is open on the outside, or an end; and an insert (25) intended to handle a lock, comprising an end introduced into said cavity (39), or a cavity, into which said end of said head (23) is introduced. The key of the invention is characterised in that the insert (25) is producedfrom a material having a melting point below that of said head (23). The invention also relates to a method for manufacturing a key (21) comprising a head (23) comprising a cavity (39) that is open onthe outside or an end. The method of the invention is characterised in that it comprises a step of injection moulding a material having a melting point below that of said head (23), produced at saidcavity (39) or a cavity of an insert (25), into which the end of said head is introduced, so that said material fills said cavity (39) or said cavity of said insert (25), until an insert (25) is obtained that is intended to handle a lock.

Description

technical field [0001] The invention relates to a key for a motor vehicle intended to lock / unlock a security door leaf, a starter's lock, etc. [0002] The invention also relates to a method for manufacturing such a key. [0003] More specifically, the present invention relates to emergency keys. Background technique [0004] Indeed, the "key" is now increasingly in the form of an electronic badge identifying the authorized user of a motor vehicle, for example allowing the locking and / or unlocking of one of the door leaves of his vehicle. [0005] For increased security and in the event of an electrical failure, for example, it is often provided that an emergency key is inserted into the badge. The emergency key can thus be removed in order to gain access to the vehicle and start it. [0006] According to the international application WO 2004 / 076783 A1, a motor vehicle key housing is disclosed comprising: [0007] - an emergency key comprising a key head fastened to each...
