- the key has a button on or in the key row.
- the key chain only comprises a single button.
- the button is preferably located on the circuit board and therefore inside the housing described. In particular, only a single button is provided, so that the user does not have the choice between several buttons, but can only press this one button.
- the housing preferably has an actuation section. This operating section can be pressed by the user. In particular, the user presses the actuating section on one broad side and supports the key blade with an opposite finger or hand on the opposite broad side.

- the transition from one wall thickness to another wall thickness can occur abruptly at a step or the wall thickness can change continuously or in several steps.
- the transition from one wall thickness to the other wall thickness does not necessarily have to be at the transition from the actuation section to the support section. It is important that the changing wall thickness enables a correspondingly flexible design of the housing, so that the actuating section can be easily pressed inwards towards the button.
- the change in wall thickness is particularly “internal”, so that a flat end surface results on the external surface of the key strip and the difference in wall thickness is not visible.
- the support section in particular a one-piece one, forms the housing on the narrow side of the key bow. If the key is viewed along the longitudinal axis or along the width axis (i.e. when viewing the front, back or narrow side), the frame section in particular and thus at least part of the support section of the housing can be seen - partially hidden by the surrounding frame.
- the housing preferably has a support column to limit a path when the actuation section is actuated.
- This support column prevents the actuation section from being pressed too hard on the button.

- the electronics send over the After pressing the button, the wireless communication module sends out a corresponding signal to establish communication with the device.

- different information about the key and/or the locking device can be represented by the different patterns.
- the electronics are designed to control the lighting device to display a charge state of the energy storage after inserting the key into the locking device, in particular, the representation of the charging status is one of several pieces of information that is displayed after inserting the key.
- the key is configurable in such a way that at least some of the information that can be displayed by the lighting device is not displayed by the lighting device, in particular permanently, the configuration being able to be stored in the electronics. This makes it z. For example, it is possible that certain information or its display is deactivated for certain users or certain application purposes in order to save energy and not to overwhelm the user.
