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. Show
There are locking wheel nut removal tools available from the likes of Amazon, which you hammer over the nut to cut a reverse thread, then use a wrench to unscrew it. They destroy themselves during application, so they’re single use items. 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.

What’s the point of a locking wheel nut?The idea is that while thieves may be able to remove the other nuts on a wheel, which have standard hexagonal heads, the locking nut is not so easy to remove.

How to remove locking wheel nutsLocking wheel nut removal isn’t too dissimilar to the process of removing standard wheel nuts. One end of your locking wheel nut key is likely to have a hole that will fit a standard wheel brace. Slot the other end — the keyed end — onto the locking wheel nut and turn the wheel brace anti-clockwise until it loosens. Once it’s loose enough, you can remove it with your fingers. If you’re removing a wheel due to, say, a flat tyre, just remember the order of operations: partially loosen the wheel nuts before jacking up the car and only remove the nuts fully when the wheel is fully jacked off the ground. In reverse, only partially tighten the wheel nuts before letting the car down off the jack and give them a full and final tighten when the car is back on the ground.

There are less pricey options out there though from Halfords (which, incidentally also stocks McGard products) and others. What do you do if you lose your locking wheel nut key?Purchase a new key. This is sometimes the easiest option although it can sometimes be expensive. However if you'd like to use the original locking wheel nut set you'll need to buy a new locking wheel nut key.
