information held in the key??
 

Hi, new to the Forum and have searched but didnt find any info.

A friend has told me that the key to my 2002 500SL can tell all kinds of info on the car including the mileage, the last time the car was driven and the VIN for the ca!! Is any or all of that true?? I told him it was rubbish but maybe not? does anybody know what the key can tell you?

THanks

I think that is BS

Ditto.

You would need IR/RF programmable non-volatile memory in the key for starters. And of what possible value would it be??

i think he has the key and the EIS confused
 

i know the EIS does alot cause we just had ours replaced.it recognizes each keys driver settings and controls just about every convenience option that exists.the key itself has no ability to monitor systems and store the info.the eis is a security component so it must have alot of specific vehicle info on it.

mercedes keys do not store that type of data on them. but bmw's do.
