Functional description of Nissan DPF I – key 3rd Bundle
This document gives an overview of the different device operation modes and the RF transmissions
performance of the key. In this document the device is referenced as "key", even if the mechanical
backup key might be separated from it.

1. 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 key functionality
· PASE Passive key functionality
· RES Remote engine start 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.
Short button press:
A short valid button pressing results a sending of the minimum number of the RF telegrams, as
showed on the diagram.

Long button press:
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.
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 receive 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).
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. During
the button pressing the amount of telegrams are sent on the RF channel. In this mode, RF output
power is higher than RKE mode.
