							SECURITY/CENTRAL LOCKINGS3
CIRCUIT OPERATION1
CIRCUIT OPERATION
Basic Overview ± Central Door Locking
All new Range Rover models feature Central Door
Locking.
All four doors and the tailgate can be locked and
unlocked through operation of the central locking
system, which can be operated by:

Pressing down, or lifting up, either of the front
door sill buttons.

Turning the key clockwise (to lock), or turning the
key anti±clockwise (to unlock), with the key in
the drivers door lock.

Pressing the ªlockº button, or pressing the ªun-
lockº button, on the remote handset.
The new Range Rover is also equipped with a
ªSuperlockingº feature. When the vehicle is
ªSuperlockedº, it is impossible to unlock any of the
doors from inside the vehicle by lifting any of the sill
buttons.
Basic Overview ± Alarm
All new Range Rovers are equipped with a
sophisticated intergrated security system.
The alarm system offers the following forms of
protection:

Perimetric protection against unauthorised ope-
ning of any of the hinged ªslamº panels.

Engine crank inhibit against unauthorised engine
crank.

Electronic engine immobilisation against unau-
thorised engine start.

Volumetric protection against intrusion into the
passenger compartment.
Basic Overview ± Lazy Locking
An additional feature of the new Range Rovers
security system is Lazy Locking.
Lazy Locking enables the driver to close any open
glass panel (window or sunroof) from outside the car
using either the key or the remote handset.
Lazy Locking can be carried out either when locking
or super locking the vehicle, or when the vehicle is
already in a locked state.
N.B. Activation of a lazy locking sequence will be
dependent on market requirements.
General
The vehicle locking and security system comprises
the following components:

ªCº type latches on the passenger doors incorpo-
rating central door locking, superlocking and
slam locking facilities.

An external key barrel on the drivers door, allo-
wing central door locking, superlocking and un-
locking, with mechanical override via key (exclu-
ding superlocking) in the event of a power failure.

Separately controlled central door locking actua-
tors on tailgate and fuel filler flap.

Ultrasonic movement detector, located over the
LH ªBº post.

Under bonnet mounted alarm klaxon.

Radio Frequency remote key allowing locking,
superlocking, unlocking and lazy locking.

Inertia switch allowing unlocking in the event of a
crash.

Security LED to indicate the ªalarm activeº state. 
						

							SECURITY/CENTRAL LOCKINGS3
CIRCUIT OPERATION2
Remote Handset Operation
The handset has two buttons, lock/superlock and
unlock. The operation is as follows:

Lock ± single press of lock button

Superlock ± double press of lock button (within 
1 second)

Unlock ± single press of unlock button from ei-
ther locked or superlocked.

Lazy lock ± press and hold lock button for more
than 1 second

(NB hold on second press if superlock required
as well.)

Lazy Seats ± press unlock button for more than
1 second.

(NB This will unlock as well)
Locking operation
There are six different ways to lock a new Range
Rover. These are:

Sill Locking
Depressing either of the front door sill buttons while
both front doors are closed will result in all the doors
and the tailgate locking, and the vehicle entering a
sill locked state.
In this state the alarm remains inactive (provides no
protection), with no LED flash.
Sill locking can be achieved independently of key±in
and ignition switch status.

Slam Locking:
Depressing either of the front door sill buttons with
either front door open, will result in all the doors and
the tailgate locking and the vehicle entering a slam
locked state.
Following a slam locking operation, the alarm will
enter the perimetric mode, engine crank will be
disabled and electronic engine immobilisation will be
activated.
Attempting to slam lock the vehicle with either the
key in the ignition, or the ignition on, will cause
unlocking of all the doors.

Key Locking
A single turn of the key towards the front of the
vehicle will result in all the doors and tailgate locking.
The alarm will enter the perimetric mode, engine
crank will be disabled and electronic engine
immobilisation will be activated.
Key Superlocking
A double turn of the key in a clockwise direction (i.e.
towards the front of the vehicle) within 2 seconds,
provided the doors, tailgate and bonnet are closed,
will result in all the doors being superlocked.
The alarm will enter the perimetric mode, engine
crank will be disabled and electronic engine
immobilisation will be activated.

Remote Locking
A single press of the lock button on the remote
handset will result in all the doors and the tailgate
locking.
The alarm will enter the perimetric mode, engine
crank will be disabled and electronic engine
immobilisation will be activated.

Remote Superlocking
A double press of the lock button on the remote
handset within 2 seconds, provided the doors,
tailgate and bonnet are closed, will result in all the
doors being superlocked (subject to ultrasonic look
around ± see Ultrasonic Sensor).
Providing all the windows are closed, the perimetric
and volumetric alarm will be set. If all the windows
are not closed, then only the perimetric alarm will be
set.
Engine crank will be disabled and electronic engine
immobilisation will be activated. 
						

							SECURITY/CENTRAL LOCKINGS3
CIRCUIT OPERATION3
Lazy Locking
Lazy locking can be carried out when either locking
or superlocking, or when the vehicle is already in a
locked state, by either holding the key turned to the
lock position or by holding the remote handset lock
button pressed for more than one second.
This will cause all the open windows to start closing
simultaneously. Closure of the windows will be
followed by closure of the sunroof.
Dependent upon market requirements, lazy locking
will either operate in one±shot mode, or in dead
mans handle mode.

In one±shot mode, the windows and sunroof will
continue to close even after the key has been
released from the lock position, or the lock but-
ton on the remote handset has been released.

In dead mans handle mode, closure of the win-
dows and sunroof will only continue for as long
as the key is held to the lock position, or the lock
button is pressed on the remote handset. In this
case, failure of any of the apertures to be fully
closed upon release of the key/button will result
in a mislock.
Mislock
A mislock condition is indicated by either two short
ªbeepsº from the alarm sounder, or by three short
flashes of the courtesy lights, depending on the
market legislation.
Partial Arming Of The Perimetric Alarm
If the perimetric alarm is armed with one (or more) of
the doors, or the tailgate, or the bonnet open, then
the remaining panels are all protected by the alarm.
If any of the open panels are subsequently closed,
then they too will be protected by the alarm.
Security LED
The security LED has two functions:

Firstly for the initial ten seconds after a lock re-
quest, it provides visual confirmation of the lock
status.

Secondly, after this confirmation period, it acts as
a deterrent to any theft attempt, (flashing at a
slower rate).
Volumetric Protection
Volumetric protection, (protection of the vehicles
interior), is provided by an Ultrasonic Sensor and
an Ultrasonic detector.
If the vehicle has been successfully superlocked with
the key, then provided all the windows are closed, asingle press on the remote transmitter lock button
will activate the ultrasonics. There is a 5 second
settling period before movement can be detected.
Engine ImmobiIisation (Petrol)
There are two methods of Engine Immobilisation
featured on the new Range Rover; engine crank
disable and electronic engine immobilisation. The
electronic engine immobilisation is controlled jointly
by the engine management systems Electronic
Control Module and the BeCM.
If a crank signal is detected when the alarm is set,
the ªEngine Immobilisedº message will be
transmitted to the instrument pack, and it will not be
possible to start the engine. 
						

							SECURITY/CENTRAL LOCKINGS3
CIRCUIT OPERATION4
Engine Immobilisation (Diesel)
The electronic engine immobilisation feature fitted to
the diesel engine derivatives is different to the
system fitted to the petrol versions.
The engine immobilisation output will be low if the
alarm is set. If a crank signal is detected with the
alarm set (armed), the ªEngine Immobilisedº
message sequence will be transmitted to the
instrument pack.
Alarm Triggering
The perimetric alarm will be triggered by any of the
doors opening, the tailgate opening, the bonnet
opening, the ignition key being inserted, the ignition
being turned on, or the inertia switch being tripped.
The volumetric alarm will be triggered by any
movement within the passenger compartment.
The alarm will be triggered a maximum of three
times during any set/unset period. Any further
triggers after this will be ignored.
Audible/Visual Warnings
A disc horn, mounted under bonnet, is used as the
alarm sounder. The output from the sounder is either
pulsed or a continuous tone, depending on market
legislation. If the output is pulsed, then its status will
be synchronised with that of the visual indicators.
The lamps used for external visual indication are
dependent upon market legislation, but will be either
Hazards, or Side and Tail, or Dip and Tail.
