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: 

Replacement fobs & cases can be purchased here:  Empty Cases

Replacement Complete fobs here: Remote Fobs

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. 

Many Meta alarm control units can be re-coded with two fobs & 16 digit number, call 0208 677 1999 or click here 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 car fails to start when the engine is hot (TVR's)

The M36 immobiliser:

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 Location:

Chimera; the alarm is usually located on the nearside under the dash cover (photo above) the immobiliser can be found behind the stereo - A guide of how to remove the dash cover can be found here

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).
