Hi guys,

I am facing ignition problems in my car and getting DTC for immo from both keys.
I want to flash immo off. Can anyone tell me which is the immo Soic8 (I attached photos)?
I read and right to EEPROMS with Arduino from time to time with nothing to do with cars ECU. Will I be able to right the new values for immo off with Arduino or do I have to use special software to deal with checsum or stuff like that ?

Thanks all for the help
Yaron

Many Thanks...

Do you happen to know if I need a special tool to flash it because it may have checksum like in ECU or I can just read and right it with any software possible of reading and writing ?
