Q. The key to my locking wheel nut is missing; now I have a flat tyre and cannot change it. Any ideas?
A. Locking nuts are sold with a code, so owners can order a new key from the maker. If you don’t have the code, garages have tools able to remove most nuts. Breakdown organisations such as the AA and RAC can also usually help.
A last-ditch DIY solution — provided you have a simple type of nut, without a spinning outer shroud/collar — is to take an old 12-point socket that is a little too small, hammer it until it bites onto the nut, and then twist it off with a ratchet. Don’t try this with a high-spec locking nut from the likes of McGard, though: you’ll destroy the wheel.
