Any know this wheel lug/lock? Help

[Cozmos]

Trying to get my wheels off (911sc). Previous owner installed these and no tool. Never seen a lock like this. 3 sided external lug lock.

Anyone familiar with these. Can’t seem to find a key this style anywhere

smash a cheap 12 point socket onto it, remove, throw away, replace with og lugnut

[ryans65]

harbor freight sells a remover kit that's pretty effective and cheap if the socket doesn't work

Are you sure that isn’t just a cover of some sort?

Not a cover, it’s the actual lug
