Location 

The respective KEYLESS-GO door handle (1) is located on the outside of the corresponding door

Structure 

The following components are integrated in the KEYLESS-GO door handle:

• Proximity switch on the outside of the door handle (recessed sensor area)
• Near-field communication (NFC) sensor/NFC antenna (driver's door only)
• Capacitive sensor on the inside of the door handle
• Capacitive sensor on the outside of the door handle
• Hall sensor
• Outside door handle lighting (model dependent)

Task 

The integrated component parts of the KEYLESS-GO door handles have the following tasks:

• The proximity switch detects when the KEYLESS-GO door handle is touched (comfort closing request while contact is maintained with the door handle)
• The NFC sensor on the driver's door allows the door to be locked or unlocked with a mobile phone or the digital vehicle key sticker (vehicles with vehicle access and drive authorization via mobile phone)
• The capacitive sensor on the inside of the door handle detects that the KEYLESS-GO door handle has been grasped (unlock vehicle request)
• The capacitive sensor on the outside of the door handle detects when someone touches the KEYLESS-GO door handle (request to unlock the vehicle or extend the outside door handle)
• The Hall sensor detects when someone pulls the KEYLESS-GO door handle (emergency opening request (reversing during convenience closing), window prompter, interruption of Remote Parking Assist).
• The outside door handle lighting (depending on the vehicle model) illuminates the area around the door handle when the surround lighting is activated.

The electronic ignition lock control unit or the KEYLESS-GO control unit reads in the sensor signals in a model-dependent manner.

The model-dependent outside door handle lightings are actuated by the respective door control unit.
