More conventional key systems (e.g. Honda) usually offer a "valet key" that has no fob and prevents access to the trunk.
Luckily my dream car was discontinued in 1995, so I don't have this problem.
I had a "valet key" with my 2001 Benz but by the 2004 model they had been discontinued. Dealership general manager's secretary called me yesterday to say there's nothing they can do (he's on vacation). I asked that he take this up with MBUSA and even Daimler Chrysler AG if necessary.
