These locks are manufactured by McGard making them OEMs for many car manufacturers. They cost a lot less here, and McGard will help you determine which ones are right for your vehicle. However, there are some auto manufacturers like Toyota that are the only source of parts that are suitable for their vehicles. Mcguard won't sell them to you. Don't confuse them with the cheaper ones available at auto parts stores. They're computer generated and the key fits very snugly - seems almost impossible to remove with any tools, and you can't buy them anywhere. There is more than one version of each model, so it's unlikely someone else will have a key that suits you. You register them with McGard and only you can buy a new key. If you have an expensive car and/or wheels these are the only locks to consider.
