Abstract

An electronic key for a security system including an access control system and/or driving authorization control system, for a motor vehicle, with a housing within which electronics for wireless communication with the security system are disposed. The key further includes a holding compartment formed in the housing, wherein the holding compartment an energy storage device for supplying electrical energy to the electronics is located. A cover is releasably fastened on the housing and sealingly closes the holding compartment in an inserted position of the cover. The key further includes a slot formed on the housing for receiving a mechanical key. A mechanism is disposed within the slot such that the mechanism can be activated by moving the mechanical key within the slot, whereby detachment of the cover from the housing can be effected.

First claim

The invention claimed is:

1. Electronic key for a security system which comprises in particular an access control system and/or driving authorization control system, for a motor vehicle, with
a housing within which electronics for wireless communication with the security system are disposed,
a holding compartment formed in the housing, wherein inside said holding compartment an energy storage device for supplying electrical energy to the electronics is located,
a cover which is releasably fastened on the housing and sealingly closes the holding compartment in an inserted position of the cover, and
a slot formed on the housing, the slot having an opening through which a mechanical key is received,

wherein
a mechanism is disposed within the slot such that the mechanism can be activated by a movement of the mechanical key within the slot, whereby detachment of the cover from the housing can be effected,

wherein
in an introduced position of the mechanical key the entire length of the mechanical key extends inside the slot, and in an operational position of the mechanical key the mechanical key extends partially out of the slot,
wherein
the slot is configured such that in the operational position the mechanical key is at least partially able to be rotated and/or pivoted and/or tilted inside the slot; and
wherein the mechanism comprises a springy catch element disposed within the slot, the springy catch element has a head area which extends into the slot through a recess formed at the base of the slot, the head area is releasably fastened with the base of the slot, and the head area of the springy catch element is structured to be spaced apart from the mechanical key in the introduced position, and
wherein the recess is located in a region that is not visible through the opening of the slot,
wherein the mechanism is structured to be activated by at least partial rotating, pivoting, or tilting of the mechanical key in the operational position of the mechanical key whereby the movement of the mechanical key acts on the head area such that along with its head area, the springy catch element is moved from the slot resulting in detachment of the cover from the housing.
