1 General Product Information
This document gives an overview of the different device operation modes and the RF transmissions
performance of the key model TXN3. In this document the device is referenced as "key", even if the
mechanical backup key might be separated from it.

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
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 125 kHz data telegram. When the key receives a valid LF message, it responds with
two RF telegrams and the inter telegram timing in this mode depends on the key configuration data (sort
of time slot concept).
The Low Frequency stage operates at 125 kHz.

3 Button functions
The validation of the accurate frequency deviation and the measurement of the transmission function of
the key are implemented basing on RF test software. The graphic below shows the functionality of the
buttons.
