2 Operating modes

The key has three main operating modes which differ regarding of the signal transmitting with the
RF (Radio Frequency):

 Immo Immobilizer transponder mode
 RKE Remote keyless functionality
 PASE Passive key functionality
 RES Remote Engine Start functionality, is an RKE mode

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

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 (if a button is released, the
transmission will be stopped within less then 5 seconds) 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 at 433.92 MHz.

The (LF) Low Frequency stage operates at 125 kHz

2.4 Remote engine start functionality

This mode refers to use the key as a remote control unit to initiate actions on the vehicle such as start
and stop engine. RF transmission depends on a user activating (a button pressing) on the key. In this
mode, RF output power is higher for a greater range (only at model TXN6 and TXN7) than in normal
RKE mode.
