Problem: Customer brought me his Nissan Qashqai J10 model from 2010. He could not start the car. Car has the I-Key system (Keyless). Smart keys have integrated mechanical flip-keys. They look like that So, when I open the flip-key and put it into ignition, car starts, but no remote locking/unlocking and no keyless start is possible. I-Key module is completely dead, I can’t connect to it. When I connect second-hand I-Key module, diagnostic connects, I get the red “key” lght on dash, meaning that key is not paired to I-Key module. I have VVDI2, VVDI Key Tool Plus, SMOK and AVDI. None of those tools want to write keys to the used I-key module. I think it must be programmed and paired to the BCM first. But I can’t do this with any tool. When I opened the I-Key module, I don’t see any EEPROM. Only Fujitsu MCU. It’s based on MB90F347A processor.
