Hi, the keys never go wrong, so must be faulty immo or power supply to ecu, (relays and fuses, connections around battery area). No point in getting immo off if the power is missing to ecu!.
Master key can be made, but no point because you can easily clone the existing key to make keys. Master is made by reading the yellow immo box eeprom and re-producing key.
A faulty immo can be relaced by swapping the eeprom over in new and old immo box.
