There are two separate buttons each one for lock and unlock the vehicle.All vehicles with a boot lid are equipped with a third button for unlocking the boot lid.The key is provided with a fourth button to activate the “PANIC” function for vehicles intended for the USmarket.The function is activated by pushing a button, the method of button pushing determines the functionactivated 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 specialfunctions 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 thepermissible ISM band. The radio receiver installed within the vehicle is able to receive the messagedischarged from the key on all 3 channels, evaluate it and send an appropriate control message to thecentral locking system.1.1.2 Drive permission with BASIC KeyAfter the key is pushed into the EZS (electronic ignition switch) a cryptographically, bidirectionalcommunication by infrared light is initiated. As there is a successful authorization of the key the engine of thevehicle can be started.1.2 Operation of KEYLESS GO KeyThe KEYLESS Go key model is equipped with all of the BASIC model functions.Additional the KEYLESS GO model only facilitates full utilisation of the drive permission system function onthe vehicle without active operation of the key. This means that one can lock and unlock the vehicle (accesspermission) without operating the key and activate and deactivate the immobiliser (drive permission) withoutplacing the key in the ignition switch. It is only necessary to carry the key in order to be identified as anauthorised 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 LFreceiver ASIC. Additionally, the keyless go variant of the key is equipped with a special HF ASIC, whichfacilitates bidirectional HF communication.

Nos reservamos todos los derechos..form 659.021.2.1 Access permission with keyless entryThe keyless access permission (keyless entry) is initiated by the vehicle user activating the vehicle doorhandle. This causes the vehicle to send an inductive wake up message. On receiving this, the key starts inactive mode.The vehicle now sends further unmodulated, inductive fields which enable the key to ascertain its position inrelation to the vehicle on the basis of field strength measurements.Bidirectional HF communication follows, in which cryptographically encrypted authentication data istransferred 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.1.2.2 Drive permission with keyless goIn principle, when activating the start/stop button for a keyless engine start, the same process runs as thatdescribed for access permission of the BASIC model. The difference here is that the key must be locatedinside the vehicle, but needs not to push into the EZS (electronic ignition switch).The presence of the key inside the vehicle is verified on every 5km driven, and on driving away. Theprocess that runs here is similar to the engine start process, although shorter.The cryptographically encrypted authentication between key and vehicle is accomplished by a bidirectionalRF communication.1.2.3 LF / HF transferralThe inductive wake-up message is sent in a phase-modulated (PSK) format through the vehicle on thefrequency 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 10kBd.1.2.4 Operating frequencies of HF transferral1.2.5 1-channelIn 1-channel operation, the mid-frequency of the channel is:ECE: 433.92 MHzUSA, Japan: 315.00 MHz
