Had a weird one, and wondered if anyone else had come across a similar problem and maybe solved it. Pressed the key in to release it and rather than having to give it a little pull to get it out,m it shot out and now is loose in the slot. It still turn the car on and off but you can remove it quite happily while driving along, and turn the car off by pushing a finger in. I imagine its something that normally locates with the grooves on the sides has not snapped back into place, but wondered if anyone had seen this before.

Any help gratefully received
