All vehicles with a boot lid can also be equipped with the function for unlocking the boot lid, and it is also possible to provide a button to activate the “PANIC” function for vehicles intended for the US market. The function is activated by pushing a button, the method of button pushing determines the function activated on the vehicle, e.g. prolonged pressure on the button initiates an IR comfort function. If messages are discharged from the key, the access permission information is sent via radio waves (HF) and redundantly via infrared (IR) from the key to the vehicle. The so-called comfort signals are special functions which require visual contact with the vehicle. Upon pressing the button for an extended period, these signals are sent via IR signal only after the standard access permission message. HF communication via 3-channel operation: The access permission message is sent sequentially on 3 radio channels adjacent to one another within the permissible ISM band. The radio receiver installed within the vehicle is able to receive the message discharged from the key on all 3 channels, evaluate it and send an appropriate control message to the central locking system. 1.2 Keyless operation The principle keyless go functionality facilitates full utilisation of the drive permission system function on the vehicle without active operation of the key. This means that one can lock and unlock the vehicle (access permission) without operating the key and activate and deactivate the immobiliser (drive permission) without placing the key in the ignition switch. It is only necessary to carry the key in order to be identified as an authorised vehicle user. In addition to the basic variant, the keyless go key is expanded to include an LF receiver component, comprising of inductive antennae which create the three spatial directions x, y and z, and an associated LF receiver ASIC. Additionally, the keyless go variant of the key is equipped with a special HF ASIC, which facilitates bidirectional HF communication. In addition to the keyless go functionalities described, the keyless go key is also equipped with all of the basic variant functions. 1.2.1 Access permission with keyless entry The keyless access permission (keyless entry) is initiated by the vehicle user activating the vehicle door handle. This causes the vehicle to send an inductive wake up message. On receiving this, the key starts in active mode. The vehicle now sends further unmodulated, inductive fields which enable the key to ascertain its position in relation to the vehicle on the basis of field strength measurements. Bidirectional HF communication follows, in which cryptographically encrypted authentication data is transferred between the key and the vehicle. If the key is outside the vehicle, the vehicle is locked or unlocked following transferral of the correct data.

The difference here is that the key must be located inside the vehicle. The presence of the key inside the vehicle is verified on every 5km driven, and on driving away. The process that runs here is similar to the engine start process, although shorter. 1.2.3 LF / HF transferral The inductive wake-up message is sent in a phase-modulated (PSK) format through the vehicle on the frequency 21.845 kHz with a data rate of 5.461 kBd. With respect to bidirectional HF communications, these are processed in a frequency-modulated (FSK) format, in the ISM band on 433.92 MHz in Europe and 315 MHz in the USA. The rate of data transferral is 10 kBd. 1.2.4 Operating frequencies of HF transferral 1.2.5 1-channel In 1-channel operation, the mid-frequency of the channel is: ECE: 433.92 MHz USA, Japan: 315.00 MHz 1.2.5.1 3-channel The following table shows the mid-frequency of the individual channels for each frequency band.
