Lugs / Key Broke, HELP (Pics inside) Options

[JoKeRkId613]

I need help. I was trying to take my rims off to put the stock 14" tires on because I need to refurbish some of the rims. I kinda broke the key that takes my lugs off. So I went to Advance Auto Parts and the guy told me I needed to buy a deep socket. I don't think the guy knew what he was talking about... I don't have stock lugs. My neighbor said something about grided or gorilla lugs... I'm not sure. But the point is, I have two problems.

I need to know where I can find anohter key to take off / put on the lugs. Anyone know where I can find one and the specific name for these?

AND

If you look at the last pic, you'll notice the broken piece got stuck around the lug. Any ideas on how to remove this?

Thanks.

isnt that a universal key that enkei makes? my gf has that same kind of key..try going to discount tires or somewhere where they sell enkeis and see if they have keys for sale.
