Immobiliser Emulator Service Mazda MX5 MK2.5 2001 - 2005 1.6 1.8

Do you have a MX5 MK2.5 2001 - 2005, 1.6 or 1.8 with an intermittent non start problem?

More and more of the original TRW(ex Lucas) factory immobilisers, marked TRW 36AS are failing. It may begin with an uncharacteristic non start that does not recur for a month or more but is a sign that the immobiliser is starting to fail. The situation will get worse and finally the car will not start at all. Until very recently the only cure for a faulty immobiliser was to replace all associated components including the ecu which really has to involve the same immobiliser part apparently living on borrowed time. No new TRW immobilisers available and not realistically possible to program a used one to the existing ecu. We have developed an emulator that replaces the immobiliser and will resolve your faulty immobiliser and associated non start problem.

Please make sure your immobiliser is marked DC69 67 5G2A/B, TRW 36AS. The emulator fits to the existing immobiliser plug and mount on the car and allows your car to start every time.

In order to supply the MX5 MK2.5 emulator, I simply require a photograph of your immobiliser labels after purchase.

If you would like to discuss this product in more detail first, please buy my MX5 Advisory Service offered here and we can talk. I will discount the cost of the Advisory Service from any subsequent purchase. From experience to date buying the advisory service to establish the nature of your fault and confirm the best solution is highly recommended.
