2 Operating modes
The key has three main operating modes which differ regarding of the signal transmitting with the
RF:
Immo Immobilizer transponder mode
RKE Remote keyless functionality
PASE Passive key functionality
2.1 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.
2.2 Remote keyless functionality
2.2.1 All key functions
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 at 433.92 MHz.
A short valid button pressing results a sending of the minimum number of the RF telegrams.
If the duration of the button pressing extents the time required for transmitting the minimum amount of
RF telegrams, additional telegrams will be sent until the button is released or a timeout of 10s is reached.
This timeout function prevents the unintended transmission over the extended time periods in case of a
button was fixed.
2.3 Passive key functionality
For passive key operation no user action on the key side is required. The trigger is delivered by the
vehicle via an LF data telegram. When the key receives a valid LF message, it responds with two RF
telegrams.
The Low Frequency stage operates at 125 kHz.
