This topic has probably been discussed before but I have the cakecutter type locking wheel nuts and my key has sheared and I don't have the code.   I tried my local dealer and he did not have my pattern amongst his stock of keys and I have tried McGard in Germany who said my bolts are not made by them.  Apart from trying to chisel them off and damage my wheels does anyone know either who made these locking bolts so I can try and get a replacement key or is there an easier way to get the bolts off?

Hi can you put a pic up of it may be able to see what type it is.

I've posted the photos on photobucket here

I have had this problem before when a tyre monkey snapped my key. What I did was hammer a socket that was slightly smaller than the locking bolt over the head of the bolt and loosen it using a torque wrench and extension bar, the  serrated type of socket is what you  need to use and not the type with 6 sides that looks like a nut if you know what I mean.


Edit:  Just found this video on youtube showing the method I described.

have you tried a pair of long nose pliers in the small holes

[omegadti]

the problem with trying to put a socket or the Halfords locking wheel stud remover on is that there is a hardened steel spinning collar on the heads so that you cannot do that.  The other problem is the last garage that put the wheels on used an air gun to over torque them so pliers etc will not work.  Ideally I need to find the manufacturer and ask them to supply a replacement key from the photo - I thought I had swum the channel when McGard said they could do this but then they said it wasn't theirs.

You could try cutting the collar off with a hammer and old screwdriver by using an old screwdriver as a cold chisel.

thats the worst when you get a over eager or lazy person who use a air-guns for this sort of bolt.
The only thing left if you can't get a lock nut off is to drill it out. good luck

One method ive used in the past is to lamp a slightly undersized socket on,and use one of those 12v wheel nut removers(brilliant),like in argos,and 9 times out of ten it works,and no hard work needed.

Not easy, either drilling, or get replacement key (about £25, can you confirm Tunnie).

Once you have it off, through the tinkers away, all Vauxhall locking bolts are bloody appalling...

You ain't the first and sadly will definitely not be the last. These lockbolts were badly designed by an idiot with too much time on his hands. Go to your local electric welders, there are many about and get them to electric weld, a Mig welder is best and most independant garages have them (even some diy-ers) a 12mm nut onto the locknut by welding the centre hole. After that you will find that a 19mm socket will get it off. It will be easy to with the heat generated by the welding.
After its done toss the crappy things away!!!!

I took some cake cutters of a mates car recently. Heres how, fit a 19 mm 1/2"drive socket to a long extension bar and place the socket over the locking bolt and hit very hard several times with a lump hammer until the socket goes fully home. Now waggle the extension bar from side to side until you can withdaw the socket from the locking bolt. now repeat the proceedure with an 18mm socket and finally ending up with a 17mm or maybe even a 16mm socket at which point you will have enough purchase on the bolt to turn and remove it. This method will annihilate the hardended
 steel ring. Good luck!

Thanks for all the advice but I persevered and after googling all sorts of combinations of Vauxhall locking bolts I founs a company selling a brand of bolt "as fitted by Vauxhall", they gave me the address of the manufacturer, I sent them a photo of my bolts together with scans of V5 and driving licence and they have given me the key number so I could order a replacement - so here's hoping!!!
