It depends on what system the car has. Some like the W163 (MLS) have an RFID chip, some use an infrared signal (the kind you plug in). The newer cars with the “keyless go” have an RFID that’s similar but different from the older keys with a chip and EIS. They all have limited key assignments that the system will recognize. The fancy computer can dig into that to see these assignments and what keys are active but there is some other system needed to make a new key to fit a reserved assignment. Apparently some services can take a real MB key and recode it to make it fit but a new one is factory only from what I know.
I’ve also seen that the company that made the older keys and RFID chips is no longer in business but MB might have a way to make those keys but it seems to be kinda iffy. And pricey. --FT Sent from iFōn > On Jan 30, 2023, at 12:09 PM, Allan Streib via Mercedes > <mercedes@okiebenz.com> wrote: > > I the Focus, after the last lost key, I zip-tied a key under the steering > column.
