What can I do if I've lost my locking wheel nut?

If you are faced with this predicament, there are a few options to try:

Visit your local dealership which may be able to provide a spare key or use a master key to remove the nut.
You can visit your local tyre garage which might be able to drill or cut the nut off.
Some garages also now have keys to be able to remove the locking wheel nut without having to drill or cut the nut off
