My 2005 auto nissan pulsar st-l cds faulted after I had jump started after flat batt; interior light didn't work on auto and key did not lock/unlock doors and central locking switch in drivers do didn't work either. volt tested all fuses did not show a blown fuse. each fuse was manually taken out looked at and replaced. cds worked again; don't know why, but if someone else has a similar problem check the fuses manually, also relays.

As a mechanic, i would suggest you first make sure all your doors are closing properly, if they are you may just need to pack your central locking system with powdered graphite, you can buy it from any good parts supplier, if that doesn't fix it you would be well advised to take it to your mechanic
