Well color yourself "lucky". There have been NO keys available for the 140 owners for a couple of years. MB just stopped supplying them with no explanation and no date as to when they would be available again. However, any good locksmith can make a duplicate key for about $25 with NO fob. Quite frankly the fob only works when one is very close to the car (on the 140's).
