MB (or DBAG) needs to make the tech open source ad let the matrix build new analogs. It’s basically some kind of RFID or coded RF signal. I’m not sure the 129 key itself is actually coded but obviously the fob has something in it.
My buddy had some little box that could read the RF signal from a later Benz fob and duplicate it in another fob “blank” you can buy on Amazon or wherever but the issue seems to be the tech in these particular fobs although I’m not sure. Cars with the earlier EIS needed that unit to make a duplicate but I think later cars like the keyless go versions are just a RF code that can be copied and written. He said he could make them for me if I got the virgin blanks. Once flashed the fob can’t be reused. He made me a new key for the R500, those blanks are like $10. I found the keyless go blank for $40 or $50 from some vendor, he said they were on eBay and Amazon too but I searched and it wasn’t clear what was what. He told me that basically if the key is close to the cloning device the key can be copied which has all kinds of issues with theft etc. so if he would be sitting next to someone who has a key in pocket or purse he could clone the key in just a couple minutes.
