Hello, I have an EIS from a Mercedes C220, if I put the key in the ignition, it can rotate, the key is ok, I checked it, does anyone have any idea what else I could check, there are no cold solders

Can you communicate with the module in the car? Can you communicate on the bench? Do you have the EEPROM from the processor to check it? Have you tried extracting the password by IR or BDM and creating a new key? Are you getting crank at all? Is it starting and then dying after a couple seconds? Is ELV working properly? Lots of possibilities here and your description doesn't help us a great deal.
