hello at all !!!

I need help !

Mercedes W219

EIS a211 545 23 08

MCU 1L59W

My problem :

The flash and EIS are fine! (Tested on the bench with a different EEPROM and its key, using a steering column emulator; mechanically OK). When the key is inserted, the emulator light turns green, and the key can be turned.

I have three keys for this car, and they were working before the breakdown.

symptoms : None of the keys циLoск the steering column emulator, so it won't turn!

I  suspect a corrupted EPROM.

I am  looking for help to rebuild the EPROM

attached :

one file original eprom (ori-eprom)
one file for example eprom mask 1l59w
one file for example eprom mask  4l40k (which works with its key in the EIS 1L59W)
A screenshot from R270 showing the SёяїдL number and mileage.
3 screenshots from SKC Simon Touch for maximum information, as well as details on the 3 keys.
Also, the SKC Simon Touch doesn't detect the SёяїдL number or the mileage 
(...whereas it sees it on the other two EEPROMs, but the R270 does see it.)

Thanks in advance for your help !!!
