If your vehicle is a 1995 model, it most likely features the EWS system (Factory Immobilizer).
A quick way to identify whether your vehicle is equipped with the EWS system is by checking the color of the ECU label:

Brown Label: Typically indicates a NON-EWS ECU
Silver Label: Usually means the ECU is EWS-equipped
If your vehicle does have the EWS system, you must send us the ECU, the EWS module, and at least one key for proper diagnostics.
