i’ve just purchased a 2004 SLK but it only came with one flip out key /fob. I’ve asked my local Mercedes Benz dealership and multiple auto lock smiths but no one reckons they can duplicate the key so that I have a spare. Am I asking the wrong question? I know the key will open the car but obviously without the fob the central locking wouldn’t work. But having a spare key at least would be better than nothing. Anybody know of a company that can cut a key if not replace fob as well? Any idea why my local Mercedes Benz can’t ,they did mention coming back in around 3 months??? is it cause they can’t be arsed or is the key fob etc too old?
