Quite true on the current series. Saves the workshops a lot of problems if the owner has only left the ignition key.
Anyway I can fix that too. Not that I would want to. By good fortune the modification that I made on mine for the ignition key just happens to have the same profile as the original key so I can use that too. It would not necessarily apply to modifications made to suit any other ignition key but it may be possible to work it so that both keys can be used.
The main problem was opening up the slot and the guides so that the slightly different ignition key could slide in.
