Is there a way to start the car with the blade key in an emergency? This would be the key inside the fob that comes out for valet parking. It seems the driver"s door handles has an opening for the blade key but I don"t really see any way to start the car with the blade key...

I would like to think that the MB designers would have thought of something so simple,but as hanly as it would be in an emergency it really is a big oversight IMO.

Electronic immobilizers are mandatory on most market areas, must be the case of the US, definitely so in the EU. If the car could be started with the blade key, almost anyone could copy the key and even without the key, one would be able to start the car "the old-fashioned way" by shorting wires (after all, a dummy metal key has not drive authorisation functions other than the ignition barrel preventing the key to turn, if incorrect key but the ignition switch would only act as a switch and you can do this from the wires (as shown at moves, where it often works on modern cars also ).

Passive and active anti theft systems have become a mandate forced more or less by the insurancecompanies. Still a Camry or Accord is stolen every 10 seconds.Any way my point is the W163 has a metal blade only key and the RFID chip is moldedinto the the plastic top of the key. It would have been smart for MB to do that forthe cars that have the IR ports for keys.

Electronic "tags" have been embedded in physical keys for quite a while so this is something that MB certainly could have done.So I guess the answer to my question seems to be sadly no. So if the valet people loose my key now I know that the blade key is useless for starting the car. I agree with Noodles that there should have been a provision for this...

MB used to have "transponder keys", with a better security than average transponder keys other brands have been using. They moved to higher security with the IR communication based keys (should not be confused with older MB keys that are often called IR-keys). The current drive authorisation system has been improved lately even if the keys look the same.You can always leave the key in the car and leave doors open. Almost the same as if the metal key alone would make the car start.
