**RMCtech** · 16th October, 2012, 10:23 PM

Hi, I got a A-Class W168 with no keys, need the 7935 transponder logic to make new keys

Immo is a Siemens 168 820 02 26 5WK4 735
CPU HC05 with mask 1D69J

I attach CPU Dump

I appreciate any help, I have Gambit, Zedbull clone, Ad90 to write transponder.

Thanks

Best Regards

Yes it not recognize the dump, only accept it if I load dump in the ML option as AAM or EAM but this immo is different from ML modules

So, have you have made/programmed the 7935 with the gambit in aam or eam mode,
or has brother adikk turned the dump into 8 sets of key data and you have written 1 of them to a 7935 with zedbull in 7935 transponder production mode,
Please can you verify which.
Thanks

I wrote adikk 7935 dumps to virgen pcf7935 chips, with Gambit, close them and that?s all, car started !!

Gambit can not give correct key data for this car using AAM or EAM, I waste 2 chips.

Yes I did, don't work, gambit give the exact number of active keys and write correct password in the chips but DON'T work on this Immobilizer, car show "star error"

Fortunately gambit at least wrote the correct password in the 7935, using the chips dumps from adikk I got the password and I was able to unlock both 7935 I wasted trying gambit data
