Hi everyone, I have a w203 with 4j74y dump- none of the customers keys are being accepted by the car and I think the problem might be with the dump as the keys are transmitting ok. Both keys do not suck into the ignition and the central locking on the remotes do not work either. Please see if any of you can repair this dump for me.
Thank you!

Hi Bram
Thanks for the files, unfortunately, I still dont seem to have any luck with this. Anything else I must check or do? (key still does not unlock or turn) I wrote key 3- 051 to a small black key and wrote the 4j74y processor as you sent me.
