Lost, snapped or rounded key? From our one base in Brent Cross we come out across London, the Home Counties and the Midlands, remove the locking nuts without the key, take care of the alloy, then fit replacement nuts and sort the tyre on the same visit.
Yes. We remove locking wheel nuts at your home, at work or at the kerbside without the key, taking care of the alloy while we do it. Then we fit replacement nuts, or a new locking set if you want to keep the security, and fit or repair the tyre on the same visit if that is what the nut was holding up.
A locking nut is built to resist an ordinary socket, so a lost or worn key usually surfaces at the worst moment: a flat tyre, or a garage that has turned the car away. We are fully mobile and bring the extraction tools, replacement nuts and tyre fitting equipment to the car.
Look properly before you book anything, because the key is often still in the car. If it really has gone, you have two honest options: order a replacement key using the code, or have the nuts removed and replaced.
Check the glovebox, often in the bag with the handbook. Lift the boot floor and look beside the jack, the wheel brace and the tyre repair kit, and inside the spare wheel well. Then try the boot side compartments, under the seats and the door bins. If you find a key, check the pattern matches the nut exactly and sits fully home without rocking.
Most locking sets come with a security code. It is usually on a card or sticker supplied with the set, printed on the box or bag the nuts came in, or recorded in the handbook, sometimes on the same card as the radio code. With that code you can order a replacement key from the car's dealer or from the nut maker, such as McGard. McGard's own ordering guidance asks for the code from the registration card supplied with the set.
Without the code card, a dealer may be able to identify the pattern for you. Nissan's parts shop, for example, says McGard key numbers are not stored, and that without the card a dealer uses a master set to work out the code. If the key is cracked, or the nut pattern is already chewed, stop turning it. Forcing a worn key, or a key from another car, rounds both the key and the nut.
A replacement key suits you if the car can wait and you want to keep your existing nuts. It has to be ordered and delivered, and some independent key suppliers ask for a photo of the V5C log book first, according to Auto Express. With a flat tyre today, removal makes more sense.
Either way, keep the key in the car and the code somewhere separate. Our guide to a lost locking wheel nut key covers key codes and replacement keys in more detail.
A locking nut is designed to beat improvised tools, so the method matters. Done badly, a simple removal can end with a marked alloy, a damaged stud or a nut that is harder to shift than when you started.
A keyed nut has a unique patterned head that only its matching key fits. Some add a free-spinning collar so grips cannot get a purchase. Many cars use locking bolts into the hub rather than nuts on studs, and some hide the head under a cap. We check which you have before choosing a tool.
Hammering a cheap socket on, using mole grips or chiselling the collar tends to round the nut further and can scar the wheel or damage the stud. Auto Express warns that a DIY attempt can damage the alloy and make the nut harder to remove. If the key will not engage cleanly, stop.
We use hardened extraction sockets with internal spiral flutes that cut their own grip into the nut. The socket is sized so it does not reach the edge of the wheel's nut hole, and the wheel face is protected while we work. We do not drill, weld or chisel. If an earlier attempt has already marked the wheel, we point it out before we start.
The safe methods use the nut's own pattern, or grip the nut head without touching the alloy. Anything that relies on grip, shock or heat puts the wheel at risk before the nut moves.
| Method | Risk to the wheel and car | Verdict |
|---|---|---|
| Replacement key ordered by its code | None, as long as the nut is not already rounded | Best when nothing is urgent |
| Dealer master set | Low, but only covers the patterns the dealer holds | Good if your make's dealer has one |
| Professional extraction socket | Low in trained hands | The standard method at the car, and the one we use |
| Cheap hammer-on extractor | Moderate to high: can skid on a spinning collar, crack or mark the recess | Often makes a later removal harder |
| Mole grips, chisel or a hammered standard socket | High: scars the wheel face and rarely shifts a tight nut | Avoid |
| Drilling out | High: a wandering bit can damage the wheel seat or the stud | Last resort, workshop only |
| Welding a nut on | High: heat right next to an aluminium wheel, the tyre and any pressure sensor | Not a driveway job |
A half-rounded nut is harder to extract than a clean one, which is why a failed DIY attempt tends to make the job longer, not shorter. McGard, which makes wheel locks, warns against using an impact gun on them because it can damage the lock, the key and the car.
The replacement must match the wheel, because the wrong nut can work loose or damage it. This is the part people get wrong when they buy a bag of nuts online.
Whether to fit a new locking set is your choice. A fresh set, with its code card kept somewhere separate and registered with the maker where that is offered, keeps the protection against wheel theft. Plenty of drivers prefer four standard nuts after a removal, and either is fine as long as the nut is right for the wheel. Everything is tightened with a torque wrench before we leave, and it is worth rechecking the nuts after about 30 miles (50 km), as tyre makers such as Continental advise.
We may. A locking wheel nut is a security device, so before removing one we can ask to see something showing the car is yours or in your care, such as the V5C, an insurance document or a lease agreement, along with photo ID. If the car belongs to a company or a family member, tell us on the call.
The same order every time, so the wheel comes off cleanly and goes back on correctly.
Tell us the car and where it is. A photo of the nut helps. We confirm the price and agree a realistic arrival time.
At the car we check the nut design, whether it has a spinning collar or a cap, and whether an earlier attempt has rounded it. That decides which extraction socket we start with.
The right size socket is driven onto the nut so the flutes bite, with the wheel face protected, and the nut is turned out steadily. The old nut is scrap once it is off.
We fit a standard nut of the correct thread and seat, or a new locking set, then sort the tyre if needed. Every nut is tightened to the maker's figure with a torque wrench. You pay once the job is done.
Yes. Once the locking nut is off, the wheel comes off like any other. We can carry out a puncture repair to BS AU 159 where the damage allows, or fit and balance a new budget, mid-range or premium tyre sourced to your size. Tell us about the tyre when you call so the price covers the whole job.
TyreSafe stresses tightening wheel nuts to the manufacturer's setting. Over-tightening with an air gun is a common reason keys and nuts round off, so it is good practice to have the nuts checked again after a short drive.
If the problem comes up on a motorway, we cannot work on the hard shoulder, in a refuge or in an emergency area. Follow the Highway Code, and if the car can be driven safely, get to services, a junction exit or a safe side road, then call us. If you are in danger, call 999. National Highways can be reached on 0300 123 5000.
