Hi I have a problem with EZS w203. I read this the first time.
I have damage orginal EZS form car and i bought a NEW-USED one to clone it.
I use SMOK Programer and I want copy epprom from MCU 1 and MCU2 to NEW-USED one.
But I'cant read my orginal old EZS ,MCU1 and MCU2. In NEW EZS I can read ok a both MCU's correct.
What I'm going to do to program old key to the car. Below I upload dump from MCU2 where is IMMO.
Please help What I must to do?
thanks for advance

If you can read the new, then you should be able to read the old.
Are they both the same.
And what happend to the org ezs? How did it break?

If you can not read org in circuit, take them off, then read them. If you can read them well,
you can clone data,
You can always transfer the processors itself from one to the other.

EZS does not recognize the key.
There is no communication with him.
I can read the old EZS as well as the new one, but I can't read it. Maybe the processors are damaged?
Yes, the EZS have the same numbers and the same processors and pinout is the same.
The car had a discharged battery and it was started from the starting device.
And I got such EZS for cloning.
