Lug nut issues 56k warning

I need to find a lug nut key that works on a five point lug. It has a funny shape to it of course. On each of the 5 points theres a block, but on one of the points the block is 1/2 the size of the other 4 blocks. I don't know what to do cause I don't want to have the lug torched off cause I don't want to ruin the rim. Also this one lug out of all 20 lugs is on the rim that has the caliper sticking so it needs to come off so I can fix it. I took some pics although there not all that clear hopefully they will help clarify what I mean in my description.

So only 1 lug nut that is stuck? I would just take it to a tire shop and get them to take it off. I had to do with one of mine and they dont charge much to get just 1 off. It would save you a big headache IMO

19/20 lugs are Gorilla lugs but the one lug is different. All the other rims I won't have a problem w/ but this one.

Just take it to a shop. They just beat a socket on mine and then took it right off. Then just get them to put a regular one back on it or something.

Thanks for the advice I'll do that.

Found the same lug set w/ key that I needed so I just bought it and took the one lug off I needed to get off and I took it back and got my money back.

Ha well that will work also.

All the rest of the lugs I have are Gorilla lugs and I only have 19/20 of them. How should I get another one that matches the rest? I think I will email the company and see if it's possible to get one.
