@HaroldMHedge What is a Pin Spanner?

@7783911 Could you elaborate on how you made your own key?

Alex - visit the local tire busters in your area.
You can't call them.
Most have no 'office' personnel to answer phones and a tech has to stop what he's doing to answer your question - for a job that offers a very low return for his time.
Go there in person and explain the situation - make a friend.
I can't imagine a chain tire store not having removal keys for all wheels.

I cut an old socket to match the slots required to grab the locking but

Pin Spanner Wrench
 

There are several types of pin spanner wrenches both fixed and adjustable pins for side and face holes. One you should be most familiar with is our alternator pulley wrench (999-571-047-02).

Search McMaster-Carr for Pin Spanner Wrenches. This page will list details for the various wrenches available: Pin Spanner Wrenches.

Boys i do have a feeling you do not know that the locking piece is flat with the rim.There is no spanner which can be used on it..
Alex i will go to my garage tomorrow and i will look for the socket so you have an idea what it takes to remove the rest of this lock nut.

Again if you drill it out you will be already done by now...

btw have you asked John Walker shop if he has one ??

or as Ontario said ,used old socket a try to match the holes but that requires some crafty handling of grinding tools...

Probably you can fabricate a key.
You will need a piece of round cold rolled steel, some steel pins that you can machine.
You will need:
to take measurements of the lug nut to locate the pins, a drill press, probably a lathe.
Or ask a machine shop to fabricate this part for you.
The easiest and cheaper solution has been given, use a 3/4 hole saw. Check all the posts on this subject.

Hi Alex..i looked on my old wheel lug nut sockets today and this is the closes i can match with your piece...you can have it.All you have to do is cut some steel drill bits and inserted them onto these little holes .
You can have it for free but have to pay for postage from Europe;-)

I just bought two deep six wheels that had these locks, so I ended up taking the entire front suspension home!

I removed them successfully by making my own key. I'll link to the video below but here's how I did it.

1) Cut some 3.5mm steel pins and pressed them into 4 holes
2) Layed some 1/8" curved wire spanning two of the pins
3) TIG welded the curved wire to the pins (four segments total)
4) Welded a tube and nut to the make shift segments
5) Unscrewed as if it was the real key.
6) Removed key and used it again on the other side.

Congratulations, you got a pair of good wheels without damaging those.
It seems you have a lot of tools, I would have tried to make a key before TIG welding the pins.
Well that is my opinion, but you succeeded and that is what is important.

Right, everyone's first approach will be different based on their tools and skills. I was just sharing what I did in hopes it may help someone else down the road.

Other DIY ideas
1). Drill the entire stud out...time consuming
2). Measure the hole locations and machine a new key.....expensive
3). Notch a piece of tubing that fits over the stud and try to hammer and twist at the same time.

Someone mentioned that some Porsche dealers have a special cutting tool, but I'm but sure if it cuts the nut or the stud.

I don't have the tool. There are many tools with pins in different places, so there is no one tool. I use a 3/4" deep hole saw, like the one pictured previously. Way easier than trying to make a tool. Those were the worst locks ever. The pins always sheared off.
