W211 key replacement? - PeachParts Mercedes-Benz Forum

My dad is about to buy a 2006 CDI, but the one we're looking at only has one key fob. Since 211's have electronic keys, can the computer be reprogrammed so that the missing key will no longer work, analogous to replacing the tumblers in an older MB? My mom's paranoid about somebody following him home after purchase and stealing it, and we need two keys anyway. The cost of the missing key is being factored into our dealing.

Anyway, about the car...it's pretty sweet. Black with charcoal interior; has navigation and harman/kardon sound. Start it up and you can barely tell it's diesel, plus you don't even have to pre-glow. And it's faster than his Volvo S70 turbo...

Using SDS, the missing key can be easily disabled. Takes 5 or 10 minutes.

replacement keys are cheaper now than they were a couple of years ago but the cost of having the dealer disable the missing key will likely be more than the cost of the replacement key even if it only takes them 5 minutes to do it. They won't hook it up to SDS for less than $100 based upon my experience.

Cool...might have to try to get them to factor that into the price. They're already knocking a few hundred off for a new key. Taking it to the indy tomorrow or Tuesday for an inspection.
