Let's talk about locking wheel bolts
Probably why you are here right now. What a pain they are. They tend to cause more problems than anything else. Generally either the key goes missing, or more often becomes damaged. Damage is mostly inflicted a by using an air wrench to remove the locking bolt instead of loosening or tightening them by hand.
Replacement keys are available to order, but only through a main agent who will not supply unless an original vehicle log book and proof of identity is supplied. This is awkward enough when the car is in the UK, let alone on the other side of the planet.
