Been having issues finding the right size for these lug nuts. I tried everything. No luck finding the lock key anywhere in the car's trunk, glove box, door panel or anywhere else. Super weird. Not 16, 17, 18 or 19, not 11/16

Yep, those are custom lugs which take a special socket to help prevent theft. You need the socket or contact the manufacturer to get another one. Check out the images (below). Please let me know what happens.
