I'm trying to pull the wheels from the '90 that I just purchased, but I'm not familiar with this style of lug nuts. They look like spline drive, but with the slots not spread uniformly around the lug nut. The wheels are ROH ZR6s. I know the pictures below aren't very clear, but they are the best I could take with my camera. Anyone recognize this style of lug nut or have a recommendation on how to remove them?

Sears sells a five piece lug nut removal tool just for you.

So much for safety of these "locks"...

They actually look like the Porsche system that I have on my car.

I wonder, if dealers have an assortment of keys, in case a customer forgets to leave his key when the car comes-in for service.

Yeah, I bought one of the Sears lug nut removal sets. Maybe not the one that you're talking about though. It has 3 double sided sockets but I didn't have any luck with them. The problem is that the lug nuts are completely round except for the grooves/slots. I couldn't get the lug nut removal sockets to bite into them.

Dig around the car for the special adapter for those.

A Porsche dealer does have a universal lug remover , BUT its only for Factory lug locks, I would suggest that you try the dealer and see if their lug luck remover might work.
Beyond that you could take a 12 pt socket and a few drill dowels cut down and fill in the reliefs and tap on the socket, then with an air gun try to remove the lugs use some PB on them first

I have used the Craftsman bolt outs (not the lug nut removal sockets) to get those off. You really have to beat them good (on the bolt outs) to get any bite. They will dig in eventually.

19mm bolt-out on a 3" extension, hammered on with extreme prejudice- you have to make/start your own grooves to give it a chance to bite.

I'd try a wheel shop, then the above. Dremel surgery might speed the process.

I had to deal with a set of these. Not that hard. I took some finishing nails and 'glued' them to some of the cutouts in roughly a hex pattern, ignoring any cutouts that were not helpful. Then I tapped on whatever 12 point socket fit best over them and broke the lug loose. Remove the socket before spinning the lug all the way off or it will be much more of a challenge later (sideways tap on the back of the socket.)

You can cut the nails a bit shorter and leave the points outward towards you to make it easier to tap the socket on. The soft nails deform easily to mate with the socket but bit well enough to get the lug off. I did not have to hammer the socket on too hard, just solid taps.

Thanks for the advice everyone. As I've got 18 of these to remove (2 of the lugs are standard 928 nuts), I was really hoping someone happened to know where to order the appropriate tool; however, I'll give the craftsman bolt out a try.

Thanks!

I've seen those universal sockets that have amillion spring loade3d pins in them do when you push it on the pins above the bolt headcompress leaving only the remaining pins around the outside in place to drive the nut under rotation. it your lucky when you push it on it could leave several of the pinsd in the corresponding groses and act as a universal Key for this style locking lug. see below example from Ace Hardware. I think I'v seen similar at Sears.

Already tried the Gator Grip socket as well. I received the 19MM sized version as a gift a couple of years ago. I was hopeful that I was finally going to have a use for it. Unfortunately it wasn't quite big enough to fit over the lug nuts. The larger version I found at Sears is too big to fit in the wheel lug nut holes.

All you need is the appropriate size hexagonal socket (that you can sacrifice). Then use an electric welder and carefully make 3-4 "points" on the inside of the hex, points that would match the slots on the lug nuts.

That´s how I removed 4 of these buggers in under 10 minutes.

Two suggestions:
First, call the previous owner and ask where the key socket is.
Second, as GlenL suggested, I would search the car for a bit like this:
