Hi @manuelanos
Not sure if you meant central locking using the ignition fob key or the door switches.
Are the hazard lights blinking when you unlock/lock the doors using the ignition fob key?
''If not'' have you checked/changed the battery in the key to see if that worked?
Have you checked if the 20A ''Door fuse'' #31 in the instrument panel fuse block is OK?
If both the key and the fuse are OK here's the wiring diagrams for the power door lock circuits that may help.
