Recently (February 2016) I was contacted by a company (www.lockingwheelnutkeys.co.uk) offering a worldwide service to identify and replace lost locking wheel nut and bolt keys using just a photo of the locking bolt left in the wheel - all for for £38 + P&P (at the time of writing). Now that seemed like a brilliant idea...if it worked. So I offered to test the service and you can find my full review of it by clicking here. Let me be clear, these guys haven't paid me for the review, nor am I connected to them in any way - I was just very impressed by their business and thought it might help others. From my experience all you have to do is take a photo of the locking bolt left in your wheel and they'll find the right key!
The standard type is a simple bolt or nut with a keyed face - most cars have this type fitted.
Finally, we have the "shear head" locking bolt (see the photo to the right) that are commonly found on Citroen and Peugeot cars. I haven't had any experience of these, so I got in touch with a mate "in the trade" who is used to dealing with them. In his view they are without doubt the most annoying type of locking wheel nut for any car owner. These are designed to break by shearing off and leaving the body of the bolt behind if removal is attempted without the proper key. Great idea right? Well it would be if the bolts and their keys weren't apparently prone to general failure even if you use them as intended. When they fail they'll leave you with a potentially expensive headache, so the advice is that if you have this type of locking wheel nut on your car you should replace them as soon as you can with a more standard type.
. Using the "Socket" approach shown in Method 2 will remove the shear head but leave the bolt intact (although you may have issues removing the shear head from your socket!). Method 4 is the usual solution to removing this type of bolt, but you need the "Universal" kind of locking wheel nut remover that bores into the bolt (i.e. not tools 1 or 2 shown in Method 4 below as these will just shear off the bolt head). The RAC and AA both have this kind of removal tool, as do most well kitted out garages. Method 3 is not recommended as it is likely to result in damage to your wheels as this type of bolt is highly recessed. There is one method, Method 5, which you should never attempt, leave this one to the professionals. If you are really stuck there is one further technique that may help (thanks must go to Ray, a reader of this guide, for alerting me to this) - you can modify your wheel bolts to take another key if they are of the Citroen "pin" type (see the photo to the left above). This involves carefully redrilling each bolt to take the modified pin positions of the new key. If done accurately this should be successful, but you may need a professional to do this for you which could prove expensive.
Standard Socket and Hammer: Now I know this works as I've seen it done a few times, but you do risk wrecking a decent socket, also if your bolts are on very tight or are seized it will not work at all. Simply take a standard socket slightly smaller than the locking bolt or nut and hammer it on hard. The splines of the socket will bite into the locking bolt and should hold it tight. You should now be able to undo the locking bolt... if you are lucky! Always use a splined socket like those shown in the photo, others will not work... and before you ask, no this didn't get my locking bolts off and yes it was very difficult to remove the hammered on socket to try another technique. My advice would be only to use this technique if you have nothing else available.
Torx, Drill and Hammer: This method can be useful if you have little or no clearance to hammer on a socket. However, think carefully before using it as it will prevent you from using the 'universal removal tool' described in Method 4. Because of this drawback and that fact that it is only successful occasionally I would only try this approach if you have no other option. To use this approach you need to have a large Torx or splined bit. This bit should be as large as possible and at least an T55 (11mm) Torx. You then drill a hole in the centre of the locking wheel bolt or nut (be careful) about the same size as the inner diameter of the Torx (i.e. without the splines, so 8mm for a T55 Torx) and as deep as possible (be careful with locking wheel nuts not to hit the threaded wheel stud). Finally, you hammer the Torx bit into the hole. The Torx splines will bite into the locking wheel bolt and you can then use the Torx to remove the bolt.
Make a really good strong weld with a MIG and cover your wheels so the alloys aren't splattered. Once you have them welded on there, you should be able to undo them with a normal socket. I'd always use a bolt (see photo) for this if you have locking wheel bolts rather than a socket or tube as if you mess up it is easier to get off and you may not have wrecked the locking bolt in the process so can try other techniques. However, for locking wheel nuts, a tube or spare socket should be placed over the nut and welded to it. Tubes and sockets can also be used with locking bolts and they may give a stronger joint than welding a bolt if you have the clearance to weld all the way round - if not drill holes in the side and weld into those. Done correctly this technique always works, but should only ever be used as a very last resort after methods 1, 2 and 4 have failed.
This will work 99% of the time and is by far the easiest method. In fact it is as easy as if you had the proper key... but only if you have the right sort of removal tool. Now there are loads of different types of removal tool out there.
For "spinning collar" wheel nuts and bolts like McGard, you need a removal tool that will bore into the centre of the wheel nut or bolt (see photo on the right). These are far more expensive than the more standard type, but are "Universal" and will work on both standard and spinning collar wheel nuts and bolts. In addition, they will remove the "Shear Head" locking bolts found on Citroen and Peugeot either once the shear head has been removed or with an adapter that is included in the kit. This is why a lot of garages, the RAC and AA have them and use them. Because of the price of these tools it is probably not cost effective to buy one yourself (but it may be so check out the cost first). Often if you go to an independent garage and chat nicely to the guys they'll let you use them for free (always worked for me!). If they do, buy them a case of beer, it's nice to be nice and you never know when you might need them again. Never, ever go to a dealer or the RAC and AA if you can help it as these guys will charge you up to £20 a wheel to remove the bolts - which is daylight robbery for this very simple and quick job!
Never try this method yourself always have a professional grind out your wheel nuts and bolts. This method will always work, but you are always going to end up with some damage to your wheels. If you try to do this yourself you may well end up with a ruined alloy wheel set, in the worst case you may end up with a structurally damaged and dangerous set of wheels. Even a professional will probably cosmetically damage your wheel set and while he'll get your locking wheel nuts off, he will charge you a fortune for the privilege. Finally, for locking wheel bolts, once you have ground down and removed the bolt head, you then have to find a way to remove the shaft which will be threaded into your wheel hub/disc assembly. If the thread is seized you will need to drill it out and then retap the bolt hole or replace the whole assembly. As a result, my personal recommendation is NEVER try this method unless there is no other solution, it may seem an obvious answer to your locking wheel bolt problems, but you will probably regret it if you decide to grind or drill them out!
