I wonder if anyone can help with putting back together the remote control / key? I picked up a second hand C2 last night and the first thing I did was to put the key in the ignition, turn it and it promptly dropped to bits. A piece of the black plastic had snapped inside, so I've superglued that back how it was, but can't figure out how the spring, key and silver button link up with the rest of it to get it back together again. I imagine a new unit will be a bit pricey and it should go back together easily if you know what you're doing which I don't!! Thanks
