Disarming The Alarm/Unlocking; Passive Immobilisation - Lotus Elise Owner's Handbook Manual

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 ordered, it is essential
that these numbers are recorded and kept safely with the vehicle
documents. If the codes are not available on receipt of the car,
enquire with the dealer immediately.

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 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 briefly flashing every second. With ignition on, immobilisation
is indicated by a continuously lit tell tale.
