not sure he was a technical person, however I refused his solution to my missing key problem.

however, if this is possible, I will accept it as a solution to my problem....

thanks once more...

Without changing the locks, the physical part of the key can turn the locks and open the doors. The ignition cylinder in the steering column has a system called EWS that talks to a chip in the key. If the dealer disables that missing key, if that key is ever found, it will not be able to start the car, but it can still open the doors manually. There is no EWS at the doors, only the ignition.

Not sure how much more we can explain it. Basic lock and key stuff here, mastered millennia ago...
