1. Operating modes
The key has three main operating modes which differ regarding of the signal transmitting with the
RF:
RF:
•
· Immo
Immobilizer transponder mode
•
· RKE
Remote key functionality
•
· PASE
Passive key functionality
Immobilizer Transponder mode
When the key is operating as an immobilizer transponder, the communication is done via a "contact
less interface" depending on a magnetic coupling. The transponder is the passive side of the link and
there is no RF transmission from it involved in any aspect.

Remote key functionality
This mode refers to use the key as a remote control unit to initiate actions on the vehicle such as
open or close door latches. RF transmission depends on a user activating (a button pressing) on the
key. During the button pressing the amount of telegrams are sent on the RF channel.
