I actually have a Chrysler Crossfire set of locking lug bolts on my 2007 Coupe. Bought these off an eBay vendor back in 2008. Hex Head on the locking lug has two adjoining sides skewed to require the special socket that comes with the set of 4 lugs.

Part No = JU-8220-8313 (Chrysler Crossfire Chrome Wheel Lock Set)

So there was (maybe is) a set of OEM locking lug bolts for the Crossfire. Probably just a set of M-B Locking Lug Bolts re-packaged & sold as a Chrysler product.
