Solution to the Electronic Key Mystery
Coincidently, the top part of my key broke recently (the part that holds the mechanical key in place broke off). Dealer ordered a new electronic key under warranty. Surprise! It's a new design key - looks different, a bit smaller, slightly different shape, and a different mechanism for holding the mechanical key in place.
And guess what? My 5' range for locking/unlocking went to 30+ feet, at least, immediately. This probably explains why newer MB owners don't have the range problem. It WAS a problem, and they apparently can fix it with the new generation electronic key.
My advise insist that your dealer get you a new electronic key. It IS a solvable problem, in my experinece. Accepting that a $10K Ford Focus has better range is simply unacceptable from a luxury manufacturer.
