Annex No.5

Functional description:

The basic design key is one of the components of a driver authorisation system and has the
following functions:

1.) Remote control for vehicle access (German abbreviation FZB) via radio and infrared

signals

2.) Driver authorisation (engine start-up) once the key has been inserted into the electronic1
ignition and steering lock

For 1.) a message is sent to the vehicle by the key via an HF transmitter once a button has been
pressed on the key.

2

For 2.) bi-directional communication
place using infrared light. The electronic ignition and steering key produces an inductive field
of 125 kHz for the key power supply.

between the key and the ignition and steering lock takes

Annex No.5

Functional description:

The design key is one of the components of a driver authorisation system and has the following
functions:

2.) Remote control for vehicle access (German abbreviation FZB) via radio and infrared

signals

3.) Keyless Go vehicle access

4.) Keyless Go driver authorisation (engine start-up, key search)

For 1.) a message is sent to the vehicle by the key via an HF transmitter once a button has been
pressed on the key.

For 2.) and 3.) bi-directional data communication takes place between key and vehicle via an
HF transceiver. The communication is started by the vehicle when one of the operating
elements on the door or boot is triggered.

In case 3.), when the vehicle is moving and every time the vehicle is started up, data
communication with the key takes place. This is started from the vehicle.

The key is fitted with a receiver for an inductive, low-frequency field (19.1 kHz). When a
certain data pattern is being transmitted on this frequency by the vehicle, the key is prepared
for the data communication state (wakes up from stand-by). As the functional process
progresses, the key also evaluates the receiving strength of the above-mentioned inductive field
for non-modulated transmission.
