The suspension eyelet is held by a guide arm which is movable such that the suspension eyelet is lowered into a receiving space in the key housing where it is inaccessible in its non-use positional. It can also be moved out into the use position for the purpose of suspending the electronic key.

Abstract: A door handle is mounted on the outside of a vehicle door in a deflectable fashion, and a sensor for detecting a manual deflection of the door handle relative to the vehicle door is arranged in the door handle. It is possible to trigger a vehicle function electrically with the door handle when a predefined deflection value for the door handle is reached. These measures make access to a vehicle comfortable and reliable.

Abstract: The invention relates to an electronic lock for a locking system, in particular an electronic ignition lock for a motor vehicle. The lock has a holder into which an associated electronic key can be introduced. The key, which is in the holder, exchanges at least one coded operating signal with the lock. After positively evaluating the operating signal, the holder can be moved into at least one actuating position. The lock has a blocking element which adjusts on introduction of the key into the holder and/or removal of the key from the holder. Movement of the holder is possible when the key is correctly in the holder. Furthermore, the lock has a switching element on which the adjusting movement of the blocking element exerts a switching action via a separate transmitter which can be brought into operative connection both with the blocking element and with the switching element.

Abstract: A system for automatic access or driving authorization for a motor vehicle includes a first device in the form of a control device having at least two states for engaging and disengaging vehicle door locks, an immobilizer, or the like. An associated second device is provided in the form of an electronic key, an ID transmitter, a chip card or the like. Both devices have means for transmitting or receiving signals, including a coded operating signal for authenticating the second device, so that a change in the state of the first device can be implemented when the second device is authorized. Before the second device is first activated, it is in a sleep state in which operation-independent function is not permitted and energy consumption is reduced. During a first operator-dependent authentication, the second device is changed over from the sleep state into a standby state in which an operation-independent function is at least partially made possible.

Abstract: The invention provides a method for operating a portable hand-held transmitter for a vehicle remote-control system in which a plurality of activation sequences control a plurality of assigned control functions in a normal operating mode, at least one control function being assigned to each prescribed activation sequence. The activation sequences differ in the manner and/or number of actuations of an activation mechanism of the portable transmitter. According to the invention the portable transmitter is switched over from the normal operating mode into a programming mode by means of a switch-over activation sequence which is carried out via the at least one activation mechanism. Assignments of the prescribed activation sequences and of the prescribed control functions can be changed as desired during the programming mode.
