Hi, I have a RENRDW330-09 with a missing security/serial sticker (but I can see the glue where it was - on the side). I'm not 100% it is the exact one that was factory installed since the car is second hand.
I can see a single EEPROM on the PCB near the NXP MCU, it's a 24LC32, so I2C EEPROM 32Kbit. If I read it using a I2C bus adapter, is it possible to get the radio code or modify the ROM to set the code to a known one?
Also, is there a specific method required to read it? Or can I just use i2cdump. I can attach it using a TUMPA, Arduino or Raspberry Pi. I have already desoldered it, put it on a DIP carrier PCB so I can do whatever I want to it.
