I saw some of the bad reviews but still took a chance and bought it, and I'm glad I did! (let's face it - if you're resorting to using anything outside of the supplied key for the wheel lock you know it's not going to be an easy job in front of you) This craftsman set was able to remove two stuck on wheel locks that a total of 4 replacement McGard keys couldn't budge without destroying the keys (which is what happens when an ignorant garage tech with an air impact wrench stupidly tightens wheel locks with it). Now it wasn't easy...my electric impact wrench with the craftsman tool couldn't loosen the wheel lock, but my 2 foot 1/2" breaker bar with A LOT of persistence did the job on both stuck wheel locks. Sure, using a 12pt. socket just smaller than the wheel lock would ultimately have worked also, but the craftsman set was much easier than going through the trouble with the smaller socket method.
Recently bought a car with locking lug nuts but the car didn't come with the key. I bought a set of these sockets to get the locks of and it was a waste of time and money. I've got lots of experience refurbishing vehicles but these were one of the worst tools I've purchased. I followed the instructions and all they did was spin on the locks. After about an hour of work the tools was worthless. It eventually ground down the grooves in the tool and were useless.
For a simplier fix I just got a deepwell socket that is slightly smaller than the lock and hammered it on then used a breaker bar (long rachet) to remove the lock. I was able to get all four locks off in about 30 minutes.
This socket set might work better on a lug nut but they were worthless on a locking lug. I returned the set and got my money back. While I was in the store I saw another set on their clearance rack. I kept the deepwell. I'll use it again on another wheel or other project.
These were a life saver, I had a "locking lug" set on my truck that had become corrosion-welded to the aluminum wheels and broke the lock key socket on the last lugnut. Rather than wait ten days for a replacement to ship to me from the mfg. this tools got it off the stud. Glad I found these!
