I have a 2003 micra, 5 door, 1 litre engine, tried to start car it wouldn't turn over, battery fully charged and don't think it's the starter motor even though it's not turning over as the lights on the dash are flashing erraticaly when i turn the key, there is a problem with the boot (trunk door) won't open at all, there is also problem locking/unlocking the other doors, could this trigger the emobilizer to stop the engine from turning over, is there anyway to open the back door from inside and will this allow the car to turn over, as anyone got any ideas of what the problems is....Thanks
