Lotus Service Notes Exige
EXIGE.M - ELECTRICAL
VEHICLE SECURITY
The Exige uses the same vehicle Meta security system as is used on 340R, being either an M36 T2
electronic immobiliser meeting Thatcham category 2 requirements, or, as an optional upgrade, a full M99 T2
alarm system incorporating M23 cockpit intrusion sensing and a self powered siren, which meets Thatcham 1.
The Lucas 5AS security module used on the standard Elise is not fitted. The Meta system operates as follows:
Keys & Vehicle Security Alarm
A single key operates the doors and combined ignition switch/steering lock, with a second, smaller key
type for the fuel filler cap. The head of each ignition key incorporates an electronic transmitter for operation of
the engine immobiliser and security alarm system. Duplicates of both keys are supplied with the new vehicle.
The key numbers are stamped on the keys themselves, and should be recorded by the owner and kept with the
vehicle documents to enable the dealer to have replacements made if necessary.
Standard Immobiliser
In order to provide a measure of automatic vehicle security, independent of any driver initiative, the Meta
M36 T2 immobiliser will 'passively' immobilise the engine's cranking and running circuits about 20 seconds
after the ignition has been turned off. The immobilised state will be indicated by the immobiliser tell tale
mounted ahead of the gear lever, blinking once every two seconds.
To mobilise the engine, press once the button on the transmitter key head (with ignition either on or off).
Mobilisation will be acknowledged by the tell tale being extinguished.
Upgraded Security System
For enhanced protection from theft and vandal damage, the EXIGE may be specified factory built with a
'Meta' vehicle security system which incorporates the following features:
Ingress protection using sensing switches on the front access panels and engine lid.
Selectable cockpit intrusion sensing using a microwave sensor.
Automatic (passive) engine immobilisation to prevent the engine from being started.
Self powered siren to maintain protection if the vehicle battery is disconnected.
'Dynamic coding' of the transmitter keys; Each time the transmitters are used, the operating frequency is
randomly changed to guard against the possibility of code copying.
Passive Immobilisation
In order to provide a measure of automatic vehicle security, independent of any driver initiative, the Meta
M36 T2 immobiliser will 'passively' immobilise the engine's cranking and running circuits about 20 seconds
after the ignition has been turned off. The immobilised state will be indicated by the alarm tell tale mounted
ahead of the gear lever, blinking once every two seconds.
To mobilise the engine, press once the button on the transmitter key head (with ignition either on or off).
Mobilisation will be acknowledged by the tell tale being extinguished
