Hi guys so i Did not find the socket for that lug nut in the car
How do you call this nut and where can i buy it?
Thx you,

that's a wheel lock. I suggest that you go to your dealer, they should have one.

I replaced all of the wheel locks with ordinary lugs as I garage my car at home and the "key" is, in my opinion, difficult to properly use.

Literally the first thing I did when buying my ‘06 Cayman S, and after that car was gone, it was the 1st thing I did when buying my CPO ‘15 991.1 GTS.

It may be in your tool kit, in the frunk.

As per above, if you get lucky, the security wheel bolt adapter will be in your car; glovebox, frunk tool set, somewhere, hopefully.

So after losing mine after my brake DIY change last Feb, I had to replace it. In the end, I swapped out all four security wheel bolts for standard bolts, and put the security bolts away on the shelf.

The below is after doing some research to order the replacement. It seems there are a number of different security wheel bolt options, ranging from 14 to 18 splines (square notch) and 19 to 23 splines (pointed notch). You have to go count the number of splines to fit your set of wheel bolts. The Porsche part numbers I found online for some of them are below. I've also added what I believe is the "Key" index / ID number, from aftermarket suppliers such as Temo.

955-361-957-10-055 (Key #55) 19 splines
955-361-957-10-056 (Key #56) 20 splines
955-361-957-10-057 (Key #57) 21 splines
955-361-957-10-058 (Key #58) 22 splines
955-361-957-10-059 (Key #59) 23 splines

Here is a picture of the set from Temo. I believe that the bolts on our cars are in the 3/4 (19.05mm) range, with pointed notches:


Here is an excellent post in a related thread by @bb964 with the specific part on his car, from Feb:

Amazon link to #51 (3/4", 15 notches). They have 14 variations, pick yours.


This is one of the parts I ordered, from Pelican:

Great! If you want to swap it out for a regular lug nut check to see if you have spacers, if you do, you will need a longer bolt.

Glad you found it. Now put it in the tool kit in the frunk - driver's side. There's a dedicated spot for it.
