How to program used Keyless go cards

Hello

Sorry for posting again. I just bought my 2003 CL 600 and have multiple issues.
My car did not come with the 2 KG cards and I have now bought two used cards from a scrapped car.
Is it possible in someway to program these for my car with SDS or simular or mayby without?
What I can remember these cards dont come preprogrammed when ordered but must be programmed by dealershop.
I thereby thought it might actually be possible to reuse KG cards for another car.
I have also read the thread about the KG Key upgrade from 2003 to the intergrated keys like in 2004- and that sounds really really cool, but first I really would like it to work with cards. I like the cards.
Pardon my bad english

David in Sweden

Thank you. Most interesting thread.
Unfortunately I dont have the original KG cards and can thereby not read data or resolder any chips.
I will examine this a little further this weekend, but if I understand right for now there is no known way to reprogram a used KG card?
Thank you once again.

This might be a dumb question, but if I put the KG module from the car from I bought the used KG cards from in my car. Would that possibly work?

nope
the keyless go module does not contain the security
the Eis does
only solution would be to buy a Eis + cards + shifter + engine ecu
but then you will have the wrong VIN showing up in diagnostics

Ok, but then I have to consider the upgrade instead. It seems really cool.
I have som KG issues with drivers door and gearknob that dont react. Maybe bad resistor inside.
Only passenger door and trunk react at all and react with "chipcard not recognized".
I will although try some programming this weekend with the used KG cards.

Thank you for clearing this all out.

I like the cards too, and before I discovered that the SL55 I had just bought had them, I investigated the possibility of acquiring the Keyless Go cards. From my research I can confirm everything that has been written here about this, so unfortunately, I don't believe it is plausible for your vehicle to ever use cards.

Told you, if you have keyless go installed and no cards, go for keyless go in key conversion
need just a later keyless go module and order a key from MB
