For most markets excluding North America and Japan, the remote central locking system
incorporates a double locking facility for optimum security. All locks use the Tibbe key
system, using 6 elements and 4 cuts. The keys include 'in-key' transponders which are
programmed to the vehicle engine immobilization system by using the Jaguar approved
diagnostic system.

The central locking system employs single key access to the driver door, luggage
compartment and ignition switch/steering column lock with the exception of the valet key
which gives no access to the luggage compartment.

When the vehicle is not locked, each door catch can be externally released by the
corresponding exterior door handle which is operated by a single rod. When unlocked, or
central locked, the door latches can also be released by the interior handles, each of which are
operated by a single cable. Operation of the front door interior handles will also unlock the
rear doors. Use of the key in the driver door lock cylinder operates the lock by a short rod to
provide locking of the door latch. This in turn locks all other doors and the luggage
compartment through the central locking system. These locking functions can also be
achieved by use of the remote transmitter.

NOTE:

To unlock the rear doors on a North American specification vehicle from within the
vehicle the locking lever has to be moved to the unlocked position first and then the
opening lever pulled to open the door.

All markets (except Japan), have a 'drive-away door locking' feature incorporated into the
central locking system, the system is installed during manufacturing and disabled or reinstated
with the Jaguar approved diagnostic system. The 'drive-away door locking' operates when the
ignition is in the 'on' position and all the doors are closed, all the doors will lock when the
gear selector lever is moved from the park (P) or neutral (N) position. The gear selector lever
has to be moved out of the P or N position and to a different gear position for more than one
second to trigger the system.

If the vehicle is stopped and a door is opened and closed, the doors will lock again when the
gear selector lever is moved from the P or N position to a different gear position for more than
one second. If the vehicle is stopped and a door is opened and closed, but the gear selector
lever is not moved the the P or N position, the doors will remain unlocked.

Key operation

To central lock or unlock the vehicle, the key is inserted in the driver door lock cylinder,
turned clockwise or counter clockwise respectively, and released. Holding the key in the lock
position for 1.5 seconds will close all windows. Releasing the key stops all operations. Central
locking of the vehicle locks all the doors, the luggage compartment, and sets the alarm
system. In addition to all of the above functions, double locking prevents the doors opening
from the interior. To 'double lock' the vehicle, the key is inserted in the driver door lock
cylinder and turned to the unlock position, then within three seconds, turned to the lock
position and released. The same procedure is required to unlock a 'double locked' vehicle as
with a central locked vehicle. The key is inserted in the driver door lock cylinder and turned
to the unlock position. This function can also be activated using the remote transmitter.

If an attempt is made to lock the doors through either the driver or front passenger door
interior handle, when a door is ajar, all doors will lock temporarily and then centrally unlock.

The fuel filler flap switch is used to allow the driver to release the fuel filler flap from inside
the vehicle. This function can be used at all times providing the vehicle is not locked by the
remote transmitter or the drivers door lock cylinder.

Keyless Entry

The Integrated key remote transmitter operates the following functions:

•

unlocking the driver door (market dependent)

•

unlocking/locking all doors (market dependent)

•

releasing the luggage compartment lid.

•

activate/deactivate the double locking (market dependent)

•

arms/disarms the anti-theft alarm system, interior scanning system and the inclination
sensor (if equipped)

•

activates global closing (market dependent)

•

deactivates a triggered alarm (market dependent)

Inputs and Outputs

Rear Electronics Module (REM)

The REM controls all locking functions for the passenger doors and controls the luggage
compartment release operation. The REM also has the sense inputs from the front electronic
module (FEM), driver door module (DDM), and the fuel filler flap actuator.

Driver Door Module (DDM)

The DDM controls all the locking functions for the driver door and stores the configurations
for the central locking and global opening systems.

The FEM controls the inputs to the system from the:

•

valet switch

•

interior luggage compartment release

•

fuel filler flap switch

•

hood latch switch

•

glove compartment lid

Transmitter, Keyless Entry Remote

The keyless entry/remote operated lock system is completely independent in function but
fully integrated within the DDM (except for Japan and Korea). The remote control system
consists of a transmitter and an antenna (radio frequency system).

The remote control transmitter for the radio frequency system will operate without the
transmitter being directed at the vehicle. The normal range between the transmitter and the
antenna will be up to 10 meters for the USA, Canada and the rest of the world. The normal
range between transmitter and antenna will be up to 10 meters for the UK and Europe and five
meters for Japan (dependent on the surrounding environment).

Before the remote control system can be used, each transmitter must be initialized to the
vehicle. A maximum number of five transmitters can be initialized to any vehicle. All remote
transmitters must be initialized at the same time.

The keyless entry/remote operated locks will not operate (lock button only) when the door is
ajar, the luggage compartment lid is ajar or if the hood is ajar. All the keyless entry/remote
operated functions are inhibited if the ignition key is in the ignition lock.

Locking and Unlocking

The remote transmitter is integrated into the key and contains four buttons (lock, unlock,
trunk release, headlamp convenience). To operate the system:

•

press the lock button once to activate the central locking system and the alarm system

•

press the lock button twice within three seconds to activate the central locking system,
double locking system, alarm system and the interior scanning system (if equipped)

•

press the unlock button once to deactivate the central or double locking, the alarm
system is deactivated and only the driver door is fully unlocked (this is programmable
using the Jaguar approved diagnostic system or via the key fob (press and hold the
lock and unlock buttons for four seconds)) (market dependent)

•

press the unlock button twice within three seconds, will unlock the remaining doors
(this is programmable using the Jaguar approved diagnostic system) (market
dependent)

•

press the luggage compartment release button once releases the luggage compartment
lid. The vehicles gear selector lever must be in the park position

•

press the headlamp convenience button once to activate the headlamp main beam
function, press the headlamp convenience button again to deactivate the headlamp
main beam function. This function will automatically deactivate after 25 seconds
