How to unlock the immobiliser on the Smart Fortwo?

Model: Smart Smart 450 - Years 1998-2007
Part: Checks and maintenance

If the immobiliser light appears on the Smart display and starting the vehicle is prevented, there are two possibilities. The first is to enter the cabin and lock the doors using the remote control. Next, open the car with the same remote, wait 30 seconds for the doors to automatically lock, and start the car. In this case, the car will start as if the doors had never been opened, which prevents the immobiliser from activating. In the worst case, to unlock the immobiliser, it will be necessary to perform a diagnosis using an OBD scanner, as shown in the video.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
