How to Disable the Immobiliser on a Daewoo Matiz?

Model: Chevrolet Matiz MK 1 - Years 1998-2010
Part: Checks and maintenance

If the Daewoo Matiz won't start with the key, the immobiliser may be damaged. To start a car with this issue, you need to install a specific chip. This must be installed in the ECU: the ECU is located under the steering column, in the left front pillar. To access it, loosen the four screws that secure it. Once removed, open it and insert the chip inside, connecting it as shown in the video. Once finished, you can reassemble the ECU and connect it, confirming that the car can now be started.
