Abstract
The invention relates to an electronic key comprising electronic components for receiving or transmitting signals. Said components are integrated in a housing ( ). A mechanical emergency key ( ′) is provided in case of an electronics failure. Said emergency key ( ′) can be inserted into a recess ( ) in the housing ( ) together with its key shaft ( ′). The aim of the invention is to produce a key which can be handled easily. To this end, one end of the housing is provided with a recess which is undercut at least in places and which usually prevents the inserted emergency key ( ′) from being pulled out. Usually, the key is in a holding position in the housing ( ) with an essentially positive fit. However, the emergency key can be turned in the recess ( ) of the housing ( ) from a holding position to a release position ( ′) in which the positive fit between the widening ( ′) in the key ( ′) and the recess is eliminated in the pull-out direction of the emergency key.
