These wheels were purchased as part of a Revain Warehouse offer. It was still in the package. These fit my car perfectly. The end of the wrench uses a 17mm socket, just like standard bolts, eliminating the need for two different sizes. Installation is easy, remove 1 pin, replace with one of these and repeat 3 more times. Then leave the key somewhere in the car where you cannot lose it. There is a sticker with your unique code so you can order a replacement if needed. You can leave this in the car or attach it to the glove compartment. There is a cost to ordering a replacement, as is the inconvenience of losing it (so be sure to return it to the store). You can always donate 1 to 4 sockets in an emergency, you can use a hammer to remove the locking pin (and yes, thieves have known this trick since I was told about this trick in 1986).
