Lotus Service Notes
MP.1 - COBRA VEHICLE SECURITY ALARM
The Lotus Elise/Exige prior to '08 M.Y. is fitted as standard with a Cobra 8186 immobiliser/alarm which
includes the following features:
• Elise 111R 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.
• Automatic (passive) engine immobilisation to prevent the engine from being started.
• Ingress protection using sensing switches on both doors, both front body access panels, and the engine
cover.
• 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 vehicle battery is disconnected.
• Alarm/owner transmitter programming using a Personal Identification Number (PIN).
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 vehicle. In order to allow replacement
transmitters to be ordered, it is essential
that these numbers are recorded and kept
safely with the vehicle 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 automatic vehicle security, independent of any driver initiative, the system
will 'passively' immobilise the engine's cranking and running circuits after the first occurring of the following
approximate time delays:
i) Four minutes after switching off the ignition.
ii) Two minutes after a mobilising command (see below).
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 continu-
ously.
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 immobilisation feature may be switched off by; switch-
ing on the ignition, pressing the transmitter small button, and switching off the ignition. Two beeps will confirm
'valet' activation, and the security tell tale will flash continuously, even with the engine running.
At the next arming command, the valet mode will be switched off.
Arming the Alarm
Remove the ignition key, close (and lock) both doors, and check that the engine cover and front body ac-
cess 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 transmitter fob (on cars with CDL, this action will automatically lock both doors - see
later). This command will be acknowledged by:
