If you get the ECU, immo box and key ( or at least the chip) I dont think you have to code anything for your car. you can unscrew the key reader off from around the ignition lock so you can use your original key that works the lock and hold the key reader with the new key together. If you can only get an ECU and immo without key I can make one from the immo..

Whats the part number on your ECU?
