__________________________________

From 1996 till 2002 TVR vehicles were fitted with the Meta M99 alarm & M36 immobiliser systems, both systms conform to Thatcham Cat1 status (insurance approval). These are extremely reliable systems, alarms fitted in the late nineties are still working perfectly today. There are two versions of the M99/M36 combination, the M36/M99 system were fitted up to mid 1999, after 1999 the M99T2/M36T2 were fitted. 

Technical Information:

The Meta M36T & M36T2 are Thatcham Cat 2 approved immobilisers, the earlier M36T unit interrupts three circuits, the later M36T2 interupts 2 circuits so rendering the vehicle immobile. The starter motor and the fuel pump circuits are cut and by-passed through the M36T2, once a valid Meta touchkey (model number RK36S) is inserted into the socket the M36 disarms allowing the vehicle to be started. If the vehicle is not started or the ignition not switched on within 15 seconds the immobiliser will re-arm. The M36T2 comes pre-programmed with two RK36S touchkeys, a total of 5 keys can be coded in, once this limit is reached further keys cannot be coded & the immobiliser will need to be removed or replaced. If the M36 has been paired with a M99T2 alarm (see below) this also uses up one memory space on the M36.

A new M36 only has space for three extra touchkeys. If the M36 is paired with a M99 alarm system another position is used up. Once a RK36S touchkey is coded into an immobiliser the same key cannot be coded to another immobiliser, do not purchase second hand or previously used touchkeys - they will not work. To code in a new RK36S a working RK36S is required, without which it is not possible and the immobiliser will have to be replaced or removed.

The M36T2 fitted to many TVR vehicles is paired to a M99 alarm system as standard. The connection between the two is via a digital link, as the M99 has only one memory space it can only be paired once to a M36. The M36 can be paired to another M99T2 providing a working touchkey is available and a memory space is free. There is no way to determine how many spaces are free or used up.


Common Problems:

Remote Fobs:

Fob fails to operate alarm - replace batteries and/or re-sync fob to alarm. Please note this proceedure will only work with fobs pre-coded with the 16 digit code.

Fob syncing proceedure

  1. With a working fob arm and disarm the alarm sixteen times or until the alarm stops responding, alarm now in program mode.
  2. Once in program mode press the button of the new remotes(s), press the button of the original remote(s). This must be done within 8 seconds of each action. If 8 seconds pass without any actions the alarm will automatically exit programming mode and you will have to start from step 1.
  3. Wait 8 seconds to exit learning mode.
  4. Test remotes.


Replacement fobs & cases: 

Type of TVR supplied fobs

Replacement fobs & cases can be purchased here:

Fobs

Empty Cases

To program a new fob to the M99 brain you need the code card with a 16 digit hexadecimal code number and a working fob, the 16 digit code needs to be pre-programmed to the remote (by a Meta dealer). Without either code & 16 digit code it will not be possible to code a new fob. 

The M99 can be re-coded with two fobs & 16 digit number, call 0208 677 1999 or for more info. 

To code a new RK36s touchkey to a M36 a working touchkey is required without which it will not be possible to do.

Siren problems:

Siren sounding when indicator lights are not flashing - replace siren

The siren is probably the most problematic part of the alarm system, when this goes wrong it can cause some odd alarm conditions, such as going off when arming/disarming or sounding for a few seconds while driving the car. If the siren sounds for no reason (usually the indicators do not flash) e.g. while driving the car and does no respond to the remote fobs is usually an indication the unit is faulty and needs replacing. The siren for the M99T model (M11A) is no longer available 

For the earlier M99 systems water can penetrate the M11a siren a cause a short circuit, in extreme circumstances this can cause the M99 conrol box to burn out, usually a repair will not be possible & the M99 will need to be replaced.

M99T2 fitted sirens are still available (SC1T2) and can be purchased here. The SC1T2 can also short out the alarm, this can usually be repaired, call 0208 677 1999 for more info

Please note both the above sirens are digitally controlled and an aftermarket 12 Volt siren will not work with the existing wiring.

Alarm disarms but car will not start:

If the battery has been disconnected for long periods of time can cause the immobiliser to fail, usually indicated by the LED found on the touchkey receptacle not flashing, if the immobilser fails to recognise the touchkey this is a sign the immobiliser has failed.

Immobiliser does not disarm using the touchkey

Check the contact pins within the socket are present, on old sockets these can break off. Replacement M36 sockets available here.

The M36 immobiliser:

The M36T2 immobiliser is a two circuit Thatcham approved immobiliser, it is manufactured with very high quality components to a very high standard & as such this is one of the most reliable immobilisers manufactured today, many of these systems are still working perfectly on vehicles which are well over 15 years age.
 
Problems arise because TVR have wired the immobiliser circuits the wrong way around. The M36 has two immobiliser circuits, circuit 1 can handle currents of up to 10 Amps & should be wired to the fuel pump or ignition circuit, circuit 2 is rated at 25 Amps & is designed to be connected to the starter motor circuit. TVR have wired these circuits the wrong way round, the starter goes through the 10 amp while the fuel/ignition goes through the 25 amp circuit. All being well there are no problems even though the two relays are wired the wrong way around. Problems arise when the starter solenoid begins to wear, in so doing it demands more & more power to function, when the current flow to the starter gets passed the 10 Amp limit of circuit 1 problems start. This situation gets worse when when the engine is hot which in turn makes the starter solenoid hot causing it to demand more power. This is known as the hot start problem, eventually the starter circuit will burn out causing total failure of the starter. Adding an extra 'hot start' relay to this circuit is not a permanent fix as the starter will still demand more power which could eventually burn out the ignition switch or associated wiring leading to the failure of the starter itself. Before this happens we recommend to have the starter inspected & have it repaired or replaced if found faulty.

All replacement TVR adapted M36T2 immobilisers will now be sent out with the immobiliser circuits switched to match the TVR wiring, this will now match the higher rated relay to the starter circuit of the TVR, this should cut down on the hot start issue

Alarm disarms but car will not start:

If the battery has been disconnected for long periods of time can cause the immobiliser to fail, usually indicated by the LED found on the touchkey receptacle not flashing, if the immobilser fails to recognise the touchkey this is a sign the immobiliser has failed.


Alarm Locations:


Chimera; the alarm is usually located on the nearside under the dash cover, the M36 immobiliser can be found behind the stereo (photo above)

Cerbera; the alarm & immobiliser units are mounted behind the compartment which is found behind the rear seats.

Griffith; the alarm is usually located behind/around the glovebox area.

Tuscan; the alarm can be found in the drivers kick panel behind the pedal cluster (photo below).

NEW

BLE-42 Replacement Immobiliser For TVR vehicles


Plug & Play replacement immobiliser for the Meta M36T2 unit fitted to many Lotus vehicles. Works in conjunction with or without the existing M99 alarm system. Uses ID tag technology & Bluetooth which means when the ID-Tag is near the immobiliser it will automatically disarm allowing the vehicle to start & run, once out of range the immobiliser will automatically switch on. Simple plug & play installation, simply locate the old M36T2 unit unplug & connect the replacement system, fit the two LED's & away you go (both LED's are easy fit deivices, no holes to drill). This system will work instead of or independantly of the alarm system, will also function if the alarm system is not operational or missing.

Fixes the issue whereby the alarm & immobiliser loose connection with each other


How the system works.

After the ignition switch has been switched off:

Once the ID-Tags are out of range the immobiliser wil automatically arm, meaning the car cannot be started. The arming occurs 35 seconds after the ID-Tag is out of range which is 10Mtrs approx. Once out of range the 'Opration LED' will constantly flash indicating the immobiliser is active.

Once the ID-Tag is in range the immobiliser will disarm allowing the vehicle to be started, disarming occurs 5 seconds after the ID-Tag is in range, for disarming is 5Mtrs approx. The 'Operation LED' will stop flashing,
