Mk1 Various Mazda Immobiliser Fitments Over Time
Posted: Tue Apr 18, 2017 6:18 pm
I would be interested in people’s comments here and corrections if I have got things wrong re Mazda UK supplied Mk1 cars, we know the Eunos cars did not have immobilisers factory fitted unless someone can advise this is in error. From posts on Miata.net it appears the MK1 Miata was not factory supplied with an immobiliser apart from one special edition "possibly".
The Mk2 from early1998 we know had a Lucas Immobiliser paired to the ECU or PCM, it requires a transducer type ignition key and if the ECU or immobiliser are damaged or all keys are lost, the normal path to recovery is to get a paired ecu, keys and immobiliser purchased from a scrapped car. I assume these items were fitted on the production line in Japan, can someone confirm this.
The Mk1 from some time in 1995 but possibly later until the end of production had a similar system to the MK2 but with a Temic Immobiliser component set. Again the transponder key is paired to the immobiliser and if the ECU or immobiliser are damaged or all keys are lost, the normal path to recovery is to get a paired ecu, keys and immobiliser set including the sensor ring purchased from a scrapped car. I assume these items were fitted on the production line in Japan, again can someone confirm this.
It appears that Mazda UK sometime around 1994 fitted a metal bodied immobiliser when the cars arrived at their distribution centre in the UK. The system worked by the owner touching the supplied battery operated fob to a sensor on the dash. I believe around a year or so ago someone posted a picture of the metal bodied unit that Robbie identified. I cannot find that post. I have never seen one of these Mazda UK supplied cars. Can anyone advise where the metal cased immobiliser was located in the car.
I accept that there would be cars sitting in the UK unsold for a while that may have confused the dates that these items were introduced, together with the very large number of alarm / remote central locking units that were fitted to Mk1 cars that will confuse things further. Including Mazda dealer supplied alarm systems.
