I received a new key for my 82 300D direct from Germany through a local dealer. The original key is ripping through the plastic holder and not long for this world, but works fine in every place it is supposed to work. The new key will open the doors, but not work in the ignition. Local MB dealer "tech" says the ignition switch is worn out. The door has had as many operations as the ignition, so why isn't it worn out, too? I admit the new key looks totally different from the original one. The dealer took the VIN numbers as reference when the key was ordered. Suggestions??
Thanks in advance,
