Lotus Service Notes
MP.12 - 2008 M.Y. SUPPLEMENT
VEHICLE SECURITY ALARM
The Lotus Elise/Exige for '08 model year onwards is fitted as standard with a PFK 457 immobiliser/alarm
which includes the following features:
• Lotus branded transmitter key.
• 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, the front body access panels, and
the engine lid/tailgate.
• Selectable cockpit intrusion sensing 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/owner specific Personal
Identification Number (PIN).
Transmitter Keys
Two new Lotus designed and badged
transmitter keys are provided with the car, and
combine a mechanical key blade with a three
button transmitter unit incorporated into the
key head. The mechanical key operates the
ignition switch, emergency manual door locks,
fuel filler cap (not USA) and Elise engine/boot
lid. The transmitter operates the electronic
immobiliser, alarm system and the central
locking. 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 vehicle
owner's 5-digit alarm Personal 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 programmed, it is essential that these
numbers are recorded and kept safely by the owner with the vehicle documents. It is also recommended that
the dealer stress this issue to their customers and, in the interests of customer service, keep a record in their
own database.
Replacement Keys: Additional or replacement transmitter keys may be purchased uncut/uncoded from Lotus
under part number A120H0008S and will be supplied with a blank mechanical blade for copy cutting to an existing
key. Alternatively, a cut key may be ordered from Bolton Lock Company, quoting the 4 digit 'L' key code, under
part number A120H0009S (using form LSL482c). In either case, the transmitter will then need matching to
the vehicle using the vehicle owner's 5-digit PIN, as described later in this bulletin.
Disarming the Alarm/Unlocking
When approaching the car, it is likely that the vehicle is locked and the alarm armed. The alarm red tell
tale lamp in the speedometer face will be triple flashing. To disarm the alarm and unlock the doors:
- Press the central, unlock, button on the transmitter key. The first press will unlock just the driver's door.
Two presses in quick succession will unlock both the driver and passenger doors.
- This command will be acknowledged by a double flash of the hazard lamps.
- The engine will be mobilised (see below).
- The interior lamp will fade on, and remain lit for up to 2 minutes (if set to the 'courtesy' position).
- The alarm tell tale will be extinguished.
If a door is not opened within 2 minutes, the doors will passively re-lock and the alarm system re-arm.
