Lights On Reminder Kit

The kit incorporates a dual tone buzzer that sounds when opening the car door to remind you that you have left your lights on.  Supplied with an easy to follow installation guide.  Helps safeguard against flat battery.  Click for Lights On Reminder Kit PDF.

Transmitter Cases

Although the Meta range of products are robust, occasionally new transmitter cases are required.  Usually after they’ve been through the wash.  The circuit boards can often be transferred into new cases.

Central Door Locking Motors (actuator)

These can be either a 2 or 5 wire motor.  Installed to operate the central locking and promoting door open, via the external button.  Most vehicles have a 2 wire motor for operation of the boot release.  Occasionally, adjustment of their cable is required.  Should a motor seize, it is important to replace them with a strong quality motor.

Replacement Bosch Relays

The old style Bosch fuel relays, found on the Griffith & Chimaera, can often lead to starting issues.  They are metal cased, usually with a red band running over the top.

Alarm Sirens

Body damage, water ingress can lead to faulty sirens.  The older M11A siren is no longer available.  This was installed alongside the M99T.  A replacement for the SC1 siren, installed with the M99T2, is available.  This uses a coded signal that is singular to Meta.

Replacement Batteries

Can be supplied for all Transmitter devices.

Alarm Systems HPA/B EVO 

TVRs have had various manufacturers alarms installed over the years.  The early Griffith & Chimaera had the standard factory alarm which was often upgraded by the addition of a Gemini central locking control module.  A Gemini 1002 alarm/siren often accompanied this.  Later saw the installation of Foxguard alarms, then subsequently Meta alarms.  The early Meta alarms installed, consisted of the M99T (alarm) + M36T (immobiliser) and an M23 microwave.  For the Cerbera, the microwave was replaced by Ultrasonics.  These are to be found on the top of the rear screen.  The next generation of Meta alarm was then introduced, denoted by T2 after the product number.  M99T2 + M36T2 + M23T/Ultrasonics.  They were pretty much the same in their workings with the exception of the M36T2, which had 2 circuits of immobilisation as opposed to 3, on the old unit.  Door check was also an added feature as was the new coded signal battery back-up siren.

The latest generation of Meta alarms is the HPA/B EVO range.  As the M99T/2 range of systems are no longer available, these are used on the installation of new or replacement systems.

The HPA/B EVO alarm retains the original functionality of the Meta TVR alarm as well as offering new advanced features, such as boot release.

For the “ Brave at Heart” there is an easy to follow installation guide

Dispenses with the need of having to enter the vehicle and turning the ignition on.  The Red Code Card of the alarm and the amount of transmitters programmed to the system, are required for advance programming of the interface module.  Should these not be available, the alarm system will require overwriting to produce a new Red Code Card.  This is ideal if the original has been misplaced.

As some alarm systems have boot protection, the alarm system may require disarming before operating the boot release. Again all this can be done from one transmitter.

A maximum of 7 transmitters can be programmed to control the alarm system.  Each transmitter is allocated its own position.  Positions 1 & 2 are taken with the transmitters supplied with the alarm, 3 & 4 may be taken by the boot release interface.  Their positions may be higher if previous transmitters have been supplied.

The 16 Alpha Numeric code card needs to be submitted when ordering replacement/additional transmitters.

Replacement Meta Immobiliser Dallas key RK36S.

The immobiliser has 5 locations to “hand-shake”.  Two of these are taken up with the immobiliser keys supplied, leaving three more “hand-shakes” available.  Pairing up to an M99T or M99T2 alarm will also use one.  Therefore, the majority of vehicles will have two “hand-shakes” available.  These will be reduced each time a new immobiliser key (RK36S) is introduced or the pairing of a replacement alarm.  Should the M36T/T2 not take to a new “hand-shake”, it could be they have all been utilised. Unfortunately the M36T/T2 cannot be reset.  The unit will require replacing and the alarm memory cleared to accept the replacement immobiliser.


SPECIAL NOTE: If no immobiliser keys are present but the alarm switches the immobiliser off with the transmitter, you may be able to teach new immobiliser keys, even in the absence of a working one.

Introducing a new RK36S immobiliser Dallas key:

1. Turn the immobiliser off, with either a working key or through the remote transmitter

2. Turn the ignition on for 5 seconds then off

3. Insert the new Dallas key to be learnt for 1.5 seconds then remove

4. Allow the system to immobilise then insert the new programmed Dallas key to turn it off

5. Should the key not be learnt, try again in case the timing was out


Repeat for any other keys, bearing in mind the maximum number of locations available.

NOTE: Keys from other units CANNOT be programmed.

As TVRs used various manufacturers for their alarms systems over the years, there is a variance in the style of transmitters. Early style of transmitters were from Gemini and Foxguard.

Onwards, Meta alarms became the OE system for TVR.  Each generation of the Meta alarm installed came with a different style of transmitter.  Although they looked different, their workings were the same, which meant the new style transmitters could be programmed to the older Meta alarms.  The latest generation of Meta alarms, the HPA EVO range, comes with a robust Blue Micro transmitter and a 3 button transmitter incorporating boot release.  Useful links below:
