Hello,
I purchased my 1997 (10/96) S500 from an individual, it came with only one key (remote flip type).
I've ordered two extra keys (with the transponder) from the dealer.
I want ONLY these three keys to be able to start the car.

When I called dealer, the tech on the phone said: "It's not a problem. Bring all your keys and they'll kick-out the other keys..."
I've arranged an appointment.
Dealer took my car in the service area, for about 20 min.
I was told that, for my specific year they can't do this...???

Q1: Is the dealer correct (there is no way to remove certain key(s) from DAS)?
Q2: Can I do this my self - with-out a Mercedes equipment (handheld programmer, etc.)?
Q3: Can somebody give me step by step instruction, that I can print out and give to the dealer technician?

I may be paranoid, but I don't trust the previous owner...
Thank you in advance for your time and info.
M#.
