Query: Great Concept Poor Execution

I bought this item in hopes of being able to keep the key with me, rather than try to hide the standard lug nut lock key in my car. I thought this was a great idea, however this lock does not fit over the lug nut for the spare tire on the Jeep Wrangler 2011. It would have been helpful if they listed the vehicles (with model year) that this lock would fit, or offer an option to buy a lug nut for your vehicle. So over all great concept, but poor execution for this product.
