Problems solved by technology

However, it has been proven that common manipulations of the keypad can lead to a rupture of the membrane
However, there is no possibility to replace the membrane, since the membrane is welded to the housing part
Thus, the user of the electronic key has to replace the housing or use a spare key

Embodiment Construction

[0041] figure 1 The electronic key 10 is shown only schematically, and is in data communication with a locking device 105 of the motor vehicle 100 . The new motor vehicle 100 has a locking device 105 that can be operated in at least two ways: by wireless data communication between the electronic key 10 and the locking device 105 and by a mechanical emergency key 120 that can be pulled out . However, the first mode of operation of the locking device 105 is preferred. For this purpose, the electronic key 10 essentially has an electronics unit 40 , which is powered by a battery as energy store 41 .

[0042] exist figure 2 The housing 20 of the electronic key 10 is shown in FIG. The housing 20 has a plurality of keypads 21 on which various functions can be activated. For example, the locking of the locking device 105 can be triggered on one keypad 21 and the unlocking can be activated on the other keypad 21 . The mechanical key 120 is usually integrated in one of the sides ...

Abstract

The invention relates to an electronic key, particularly for a closing apparatus (105) for a motor vehicle (100), having a housing (20) made of plastic and an electronics unit (40) for data communication with the closing apparatus (105), a holder (30) formed on the housing (20), and a cover (50) which is mounted detachably on the housing (20) and seals the holder (30). The invention provides for a container element (60) to be able to be inserted into the holder (30), where the container element (60) holds the electronics unit (40) and an energy store (41), the container element (60) has a collar element (61) and the underside of the cover (50) rests against the collar element (61).

Description

technical field [0001] The invention relates to an electronic key, in particular for a locking device of a motor vehicle, having a housing made of plastic, an electronic unit for data communication with the locking device, a key formed on said housing A receiving portion, and a cover that is detachably fixed on the housing and closes the receiving portion. Background technique [0002] In order to increase user comfort and increase security against theft, locking devices for motor vehicles are usually equipped with electronic keys in addition to mechanical keys. In order to ensure that the user can enter the interior of the motor vehicle, it is necessary to perform corresponding operations on the electronic key. [0003] This operation triggers usually a two-way data communication between the electronic key and the locking device. Within the scope of this data communication via electromagnetic waves, it is necessary to transmit a signal code for authentication of the key. ...
