2005 LOTUS ELISE engine

KEYS & CAR SECURITY ALARM
KeysA single mechanical key operates the manual door locks
(see also ‘Doors’ and ‘Central Door Locking’), combined igni
-
tion switch/steering lock, and engine cover. The head of the key incorporates a push button activated key hole light to facilitate
operation in the dark. A duplicate key is supplied with the new car and, on receipt,
should be separated and kept in a safe place for use in an emergency. The mechanical key code is printed on a plastic
tab which should be removed from the key ring and the number recorded safely with the car documents. This number will be
required when ordering a replacement, or any additional keys
from your dealer. Ensure that a spare key is available at all times to guard against becoming stranded.
WARNING: Never leave the car unattended with the key in the igni
-
tion switch, especially if unsuper vised children and /or animals are in the car. Dangers can arise from window
operation and other electric controls. If the engine is running, operation of the car’s controls could cause an

accident and result in death or serious injury.

Car Security AlarmThe Lotus Elise is fitted with a Cobra 8186 immobiliser/alarm
which includes the following features:
• ‘Dynamic coding’ of the transmitter fobs; Each time the trans
-
mitters are used, the operating frequency is random changed
to guard against unauthorised code copying.
• Automatic (passive) engine immobilisation to prevent the engine from being started without the transmitter fob.
• Sensing switches on doors, front body access panels and the engine cover, meaning the alarm sounds if someone tries to
force entry.
• Personal protection by ‘on demand’ activation of the siren.
• Selectable cockpit intrusion sensing using a microwave

sensor.
• Self powered siren to maintain protection if the car battery is
disconnected.
Transmitter Fobs Two transmitter fobs are provided with the car to operate the
immobiliser/alarm system. The two transmitters should be kept
separate, and a replacement obtained immediately after any loss to ensure that a spare is always available.
Each individual alarm system has a unique serial number
and an owner’s Personal Identification Number (PIN), both of
which are printed on a code card supplied with the car. In order to allow replacement transmitters to be ordered, it is essential
that these numbers are recorded and kept safely with the car
documents. If the code card is not available on receipt of the

car, enquire with the dealer immediately.
Engine Immobiliser In order to provide a measure of car security, independent
of any driver action, the system will ‘passively’ immobilise the
engine’s cranking and running circuits after the first occurring of the following:
i) Four minutes after switching off the ignition;
ii) Two minutes after a mobilising command (see below); or
iii) One minute after switching off the ignition and opening the driver’s door.
The immobilised state is indicated by the security tell tale in
the tachometer upper face flashing continuously. To mobilise the engine, press once, and for a full second, the
larger of the two buttons on the transmitter fob. The security tell
tale will be extinguished.
Valet Mode

If leaving the car for servicing or parking, the passive immobil
-
isation feature may be switched off by switching on the ignition
and pressing the transmitter small button. Two beeps will confirm
‘valet’ activation, repeated as a reminder when the ignition is switched off. The security tell tale will remain off. At the next arming command, the valet mode will be switched
off, and normal immobilisation resume.

Arming the AlarmRemove the ignition key, close (and lock) both doors, and
check that the engine cover and front body access panels are
secure. The roof may be either closed or open. Press once, and for a full second, the larger of the two buttons on the trans
-
mitter fob (on cars with central door locking, this action will automatically lock both doors - see later). This command will
be acknowledged by:
- 2 flashes of the hazard warning lamps;
- Continuous flashing of the security tell tale.
Check that these indications occur. If not, press the button a
second time, as the first press may have only switched off the passive immobilisation (see above). Note that if the system is armed when a door or engine cover/
front access panel is not fully closed or if the interior lamp is in the ‘off’ position, a continuous buzz will be heard as warning. If still open after expiry of the arming period, (see below)
the alarm will be armed with that switch group (both doors, or
front/rear access lids) excluded from the circuit.
After arming the system, the engine is immediately immo
-
bilised, but a period of approximately 45 seconds must elapse
before all functions and sensors become fully active. After
this time, the alarm will be triggered by any of the following actions:
- Interruption of the car battery power supply.
- Energising the ignition circuit (‘hot wiring’).
- Opening a door;
- Opening the engine cover or a front access panel.
- Movement detected within the cabin.
When the alarm is triggered, the hazard warning lamps will
flash and the electronic wailing siren will sound for a period of approximately 30 seconds before closing down and resetting, ready for any further triggering input. If a trigger is continuously
present, the alarm will repeat after a short delay, and continue
in this sequence for about 10 cycles. To silence the siren when triggered, press once, and for a full
second, the larger button on the transmitter fob. This will not affect the status of the alarm which will remain armed.

Disarming the AlarmTo disarm the alarm, press once, and for a full second, the
larger button on the transmitter fob. This command will be
acknowledged by:
- 1 flash of the hazard warning lamps;
- Extinguishing of the security tell tale. If the alarm had been triggered during the last armed period,
the disarm command will be acknowledged by the hazard lamps
flashing 4 times, and the buzzer sounding 4 times. The security tell tale will then flash a code to indicate the triggering source:
- 1 pulse flashing: door, engine cover/boot lid or body front access panel.
- 2 pulse flashing: movement detected in cabin by microwave sensor.
- 4 pulse flashing: tampering with ignition circuit.
- 6 pulse flashing: interruption of battery supply.
The coding will be deleted when the ignition is next turned
on.
Emergency disarming /mobilising If the transmitter fobs are lost or damaged, the alarm system
owner’s unique PIN may be used to disarm the alarm and/or
mobilise the engine provided that access is available to the
cabin. Follow the transmitter fob programming instructions (see
page 18) from step 3.

the doors will be ‘deadlocked’ meaning that the interior door release handles will not open the doors. In order to get
out of the car in an emergency when the doors are locked
see the section below ‘to unlock from inside’.
To unlock from inside: To unlock both doors from inside, press the left hand side of
the rocker switch on the front of the gear lever shroud, or raise
the sill button on each door. Note that in the event of a car col
-
lision which causes the safety inertia switch to be tripped, the doors will automatically be unlocked.
Pull the release handle at the front of the door and push open.
Shut the door from outside by using firm hand pressure towards the rear of the door.
WARNING: Before closing a door take care to ensure that no persons
or objects will be trapped to avoid injury or damage.
To lock from outside: To lock the car from outside, remove the ignition key, close
both doors and check that the engine cover and front body ac
-
cess panels are secure. Arm the security alarm by pressing once,
for a full second, the larger of the two buttons on the transmitter
fob. This action will both arm the alarm and electrically lock the driver’s and passenger’s doors.

Notes:
• In the event of a flat car battery, the CDL will not operate. The
doors can be unlocked from outside only after opening the
engine cover and restoring power to the battery by substitution,
re-charging or ‘jumping’ to a second battery. The doors cannot
be unlocked using the mechanical key if the CDL was used
to lock the car.
• To lock the car with a flat or disconnected car battery, or if
the transmitter fob is disabled, use the mechanical key in each exterior door lock button and turn anticlockwise to the
vertical position to disconnect each release button from the latch. This technique does not ‘deadlock‘ the interior release
handles, but does allow continued key access to the car until restoration of battery power.
Note that a door locked with the mechanical key cannot be
unlocked using only the transmitter fob.
• To deadlock the car i.e. disable interior release handles, with
a flat car battery, or without the use of the transmitter fob or mechanical key, close and lock one door using the sill but
-
ton, and for the second door, hold the exterior release button pressed in and depress the sill button before closing the door.
Access is now available only by using the transmitter fob after restoration of car electrical power.
