You guys are all trying too hard. Sunex 28402, 28403, 28404 and 28405 are what you need to remove locks. Works for all locks, and only locks. They are conical sockets, they're about $7-10 each. You can get them on ebay or your other favorite retailer. You hit it on with a hammer and take the lug off with a breaker bar. I've used these for years, it's dead simple. You can make it even easier by applying some valve lapping compound to the tool. They come in kit 2840 but the rest of the kit is a waste of space and money. I think I use 28403 the most.
