Audi A4 B5 help with immo off (eeprom 24c02)

[krzys1540]

Hi,
I have A4 B5 1.9 90km. ECU: 0281001438/439, 028906021RD
I read eeprom B58253 I/SN
I read it as Type: 24 EEPROM ; Manu: Micrchip; Chip: MIC24C02C
I read Eeprom EZP2010 but it does not want to save my memory changes. Is there an option to save the changes with this device or do I have to buy a second bone? The new bone must be locked before writing so that the driver does not make any changes? How do I block it? If what bone to buy to be able to block it from writing?
In the attachment I attach what EZP2010 downloaded to me


Thank you in advance for any help !

I have a second eeprom bone. Now upload the modified batch and then how should I block it from changing the data? I heard that something needs to be done to prevent memory modification because this driver modifies it after a few starts of the car
