4. KEYS & SECURITY ALARM

Keys

A mechanical key is used to operate the combined ignition

switch/steering column lock, and the emergency manual door

locking function via the left hand door. The keyhead incorpo-

rates an electronic transponder which communicates with a

sensor by the ignition switch to allow engine starting only with

the correct key.

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 and security system PIN

(sPeciﬁc Identiﬁcation Number) are also supplied with the keys,

and should be removed from the key ring and noted safely with

the vehicle documents. These numbers will be required when

ordering or programming replacement or additional keys from

your dealer. Ensure that a spare key is always accessible to

guard against becoming stranded.

Memorising the PIN will allow the security system to be over-

ridden in case of transmitter loss or failure (see page 20).

WARNING:

Never leave the car unattended with the key in the ignition

switch, especially if unsupervised children and/or animals

are in the car. Dangers can arise from imprudent operation

of window or other electrical controls. If engine starting

attempts are made, an accident could be caused, resulting

in death or serious injury.

Vehicle Security Alarm

The Lotus Evora is ﬁtted as standard with a PFK 457 immo-

biliser/alarm which includes the following features:

• U.K. approval to Thatcham category 1.

• ‘Dynamic coding’ of the transmitter keys; Each time the

transmitters are used, the encrypted rolling code is changed

to guard against unauthorised code capture.

• Passive activation of immobiliser, central locking and alarm

system.

• Ingress protection using sensing switches on the latches of

both doors, and the tailgate.

• Selectable cockpit intrusion detection using a microwave

sensor.

• Self powered siren to maintain protection if the vehicle battery

is disconnected.

• Personal protection by ‘on demand’ activation of the siren.

• Emergency alarm override and transmitter key programming

using an alarm sPeciﬁc Identiﬁcation Number (PIN).

• Homesafe and automatic drive along locking.

Transmitter Keys

Two transmitter keys are provided with the car, and combine

a mechanical key blade with a three button transmitter unit in-

corporated into the key head. The mechanical key operates the

ignition switch/steering lock and emergency manual door locking.

The transmitter operates the central locking, alarm system and

electronic immobiliser. The two transmitter keys should be kept

separate, and a replacement obtained immediately after any loss

to ensure that a spare is always available.

The 4-digit code for the mechanical key, the unique serial

number of the immobiliser/alarm, and the system’s 5-digit sPecifc

Identiﬁcation Number (PIN), are supplied on plastic tags attached

to the key ring of a new vehicle. In order to allow replacement

transmitter keys to be matched to the car, it is essential that these

numbers are recorded and kept safely with the vehicle docu-

ments. If the codes are not available on receipt of the vehicle,

enquire with the dealer or vendor immediately.

Disarming the Alarm/Unlocking

When approaching the car, it is likely that the vehicle is locked

and the alarm armed, as indicated by the alarm red tell tale lamp

Keys & Car Security Alarm

in the speedometer face ﬂashing once every 3 seconds. To

disarm the alarm and unlock the doors:

- Press the central, unlock, button on the transmitter key. The

ﬁrst press will unlock the driver’s door, and a second press,

the passenger’s door.

- This command will be acknowledged by a double ﬂash of the

hazard lamps.

- The alarm tell tale will be extinguished.

- The interior and mood lights will fade on, and remain lit for up

to 2 minutes (if set to the ‘courtesy’ position).

- The engine will be mobilised (see below).

If a door is not opened within 2 minutes, the doors will pas-

sively re-lock and the alarm system re-arm.

Passive Immobilisation

In order to provide a measure of automatic vehicle security,

independent of any driver initiative, the system will ‘passively’

immobilise the engine’s cranking and fuel pump circuits after the

ignition has been turned off for 40 seconds, or a similar period has

elapsed since the last mobilising command. With the ignition off,

the alarm tell tale will indicate that immobilisation is in effect by

a brief ﬂash every 1.5 seconds. With ignition on, immobilisation

is indicated by a continuously lit tell tale.

To mobilise the car (i.e. allow engine starting) with ignition on

or off, press once the transmitter centre button; the alarm tell

tale will be extinguished.

Arming the Alarm/Locking the Doors

To lock the doors and arm the alarm, remove the ignition key,

shut both doors, and check that the tailgate is properly closed.

- Press once the raised logo button on the transmitter key.

- This command will be acknowledged by a single ﬂash of the

hazard lamps.

- Both doors will be locked, the engine immobilised and the

alarm system armed. A settling period of 40 seconds must

expire before the ingress sensors become active.

- The alarm tell tale will ﬂash once every 3 seconds.

- The interior and mood lamps (if lit) will fade off.

Note:

i) If the system is armed when a door is not fully shut, three

triple beeps will sound as a warning and the doors will not

be locked. Opening a door will not trigger the alarm.

ii) If the system is armed when the tailgate is not fully closed,

three warning double beeps will be heard, and the doors will

not be locked. Opening a door in this instance will trigger the

alarm.

When fully armed, and after the settling period of 40 seconds

has expired, the alarm will be triggered by any of the following

actions:

- Interruption of the car battery power supply or siren cables.

- Energising the ignition circuit (‘hot wiring’).

- Opening a door;

- Opening the tailgate;

- Movement detected within the cabin (unless de-selected).

If the alarm is triggered, the hazard warning lamps will ﬂash

and the 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 (e.g. door left

open), the alarm will repeat for a maximum of eight 30 second

cycles before excluding the triggering sensor for the remainder

of the armed period.

To silence the siren, press once the central, disarm button on

the transmitter key. If necessary, press a second time to disarm

the alarm. Note that if the vehicle battery has been disabled, it

will not be possible to interrupt the siren until completion of the

sequence.

Alarm Tell Tale Summary

Tell tale off; Alarm disarmed, engine mobilised.

Tell tale on; Immobilised with ignition on.

Brief ﬂash every 1.5 secs; Immobilised with ignition off.

Brief ﬂash every 3 secs. Alarm armed, engine immobilised.

Turning Off the Interior Movement Sensor

A microwave sensor is mounted behind roof lining, near the

interior lamp, and is able to detect substantial physical movement

within the cockpit, and trigger the alarm.

If an animal is to be left in the vehicle, or if for any other reason

it is desired to exclude the interior movement sensor, press once

the transmitter logo button in the normal way to set the alarm,

and then press a second time (within 2 seconds) to exclude the

interior movement sensor. A single beep will be heard as con-

ﬁrmation. This exclusion will be automatically cancelled when

the alarm is disarmed.

Opening the Tailgate

To open the tailgate, press once the end button on the trans-

mitter key; the latch will release and allow the tailgate to be

opened, assisted by pressurised struts. Boot lamps will switch

on automatically whenever the tailgate is open.

To prevent unintended release whilst driving, the tailgate

cannot be opened when the ignition is switched on, but with

ignition on, an already open tailgate will be indicated on the right

hand screen in the instrument panel via the vehicle silhouette

graphic.

To close the tailgate, ensure that no persons or objects will be

trapped before pulling down the panel and pressing ﬁrmly over

the latch to assure its complete engagement. Guard against

inadvertently locking the transmitter key in the boot.

Emergency Disarming/Mobilising

If the key transmitter is damaged or fails to function, and a

spare key is not available, the alarm system 5-digit PIN may be

used to disarm the alarm provided that access is available to

the cabin:

- Turn on the ignition. The alarm tell tale will light.

- If the alarm is armed, accessing the cabin, or turning on the

ignition will trigger the alarm until completion of this emergency

process.

- Within 10 seconds, turn the ignition off; the tell tale will begin

to ﬂash.

- After a number of ﬂashes corresponding to the ﬁrst digit of

the PIN, turn on the ignition. Note that the ﬁrst ﬂash may not

be of full duration (but is still to be counted) dependent on the

waveform position at time of ignition switch off.

.- Turn off the ignition and after a number of ﬂashes correspond-

ing to the second digit of the PIN, turn on the ignition. Repeat

this process until all 5 digits have been completed. Note that

10 ﬂashes correspond to a zero digit.

- If the PIN is entered correctly, the alarm will now be overridden

and the engine mobilised. However, passive immobilisation

will still occur after an ignition off time of 40 seconds, requiring

a repeat of the above procedure to mobilise. Passive arming

and passive door locking cannot occur until a transmitter is

used to operate the alarm.

If, at any stage of the process, a number is entered incorrectly,

the system will immediately revert to the start, so that the whole

PIN must be re-entered.

Programming Additional Transmitters

A maximum of 6 transmitters may be programmed to the car,

any thereafter overwriting the ﬁrst to have been programmed.

- With the engine immobilised (tell tale ﬂashes brieﬂy once per

second), turn on the ignition.

Keys & Car Security Alarm

- Enter the PIN as detailed above, followed by the additional

two digits 1, 1.

- The tell tale will ﬂash rapidly for one second, then turn off.

- Within 8 seconds, press any button on the transmitter to be

programmed. The tell tale will then pulse rapidly and the siren

will beep.

- Within 10 seconds press any button on the next transmitter

to be programmed (if applicable), and repeat this process for

all remaining transmitters.

- When all transmitters have been programmed, wait for 10

seconds, or turn off the ignition.

To disable a lost or stolen transmitter from the system, use

the above procedure to programme 6 transmitters, if necessary

repeatedly reprogramming the same transmitter if less than 6

programmed transmitters are to be used.
