[dd1]

Hello everyone, I have purchased an EIS with a key set. I would like to use it on this 1997 c class. The original EIS won't turn the key. What should I do to get this car running? I have purchased the EIS with a key set by the original EIS part number. Thnx in advance

You'll have to renew the ESL and the ECM also. After the ESL renew, the key will work but the car won't start until the ECM is also renewed.

Thnx. What if to swap the MCUs? Do I need to swap both Mcus?

Is it possible to renew the ESL for this with help of a vvdi2 mb??????

Both mcus. As for the EIS, don't swap anything from the original, since you don't know precisely how it failed. If you can read but not renew the esl, post the dumps here and I'll renew them. Btw, are you sure the original key is ok?

I have the eis with the key. Yes I am bc I read it with vvdi2 and it read showed ok. How else can check it? Bc I had cases where the key was bad, eis wouldn't see the key and I would take the key out and try to read it the vvdi 2 mb and it wouldn't either. Then I would make a key and that's it. Thnx
