Every tool company (Snap-on, Matco, Mac etc etc) all make a special tools to get these off. Basically hammer a special socket over the locknut and zip it off w/ an impact gun. I do a couple a week w/out problem. Most people don't even know they have a lock kit let alone where the key is. I hate wasting time looking for them and I usually find some nasty s*** under the seats. Go to any independant shop. I'm sure they will take them off for you for $20. If you were near Albany, I'd take them off for free. Goodluck
