2004 Miata ECU Kit, Immobilizer, Ignition Switch, Key. Will only work for a 2004 MazdaSpeed Miatas. Comes with the ECU, immobilizer unit, ignition switch and key from the same car. These components are matched to each other so that the car's immobilizer can work effectively and allow you to start the car. Replacing the ECU alone will not allow the car to start unless taken to the dealer so it can be reprogrammed to your existing immobilizer/key, which can be expensive. The key included has normal wear and scratching on the grip as shown. You will need to reuse some of your existing hardware for installation.
Please verify your part number before ordering: BP8P 18 881D
