Auto Electrician Job - Kleinmond, WC, 7195

Having troubel. With Hyundai Matrix 1800 cc 2004 model. The ignition berrel and key was removed . I bought a second hand berrel and key and the lock smith tride to insstall it on the ECU. But the Ecu dont comunicate with his scaner. He said the ECU must be dead but the car was standing for 6 years and somebody must have remove things from the car and cut some wires. So if you can get the Ecu to comunicate with a scanner that will solf my problem.
