    I looked at another K5 yesterday. I want it mostly for parts. It has mags on it but has wheel locks and the owner has lost the key and doesnt know what kind they are. I can't cut them off with my plasma cutter, cause I'll screw up the alum. I was thinking cover the whole thing with wet rags and weld on a 1/2 drive extension. But if i burn through I'm screwed. The locks have no names on them and look like every other autozone type lock. Snapon has a kit that may/may not take them off. But its cost almost makes it not worth it. Its got centercaps on it too to even make it harder. Any ideas?

    Oh yeah forgot to say I work in a machine shop so If spmeone has an idea but it requires making some funky tool no problems. I already asked our machinist about just making a new key. He said they are hardned and he dosent think he could make anything strong enough for that many uses.

    When I used to work at the tire shop, we would sometimes have luck with Vice Grips. But it doesn't sound like you are going to be able to get a good grip with Vice Grips. When all else failed we just broke the stud off with a hammer and then replaced the stud.

    I got a trick that worked for me. I went to a swap meet and bought a selection of metric and standard 12 point sockets that looked close to the size of the locking lug nut. Then I tried each one to try and find one that I could drift over the locking nut. For me it was an 11/16" 12 point socket, it took about 6 or 7 good hits to drift over the locking nut. The ridges inside the socket made enough of a groove on the puzzle lock. Then use a bar not and impact and you should be able to back it right out. Once it is out use a punch and a vise or something to 'undrift' the puzzle lock. Worked like a hot damn for me.

    I once bought a vehicle that had locks on the wheels and I had no key. The tire shop had a special kit that they used with an impact wrench that was basically a socket that was threaded on the inside with reverse threads. It would thread itself right over the outside of the lock and take it off like a lug nut!

    Good Luck!

    P.S. The same vehicle (Jeep) had a wheel lock on the rear mounted spare that I was able to crack off with a BFH (Big F***ing Hammer) and a heavy chisel! Just don't be afraid to "give her h%ll !!!!!!

    I've heard of using a socket just larger than the nut, and rocking it until it breaks off. Not sure how that would work on a fully seated lug nut, but could be worth a try....studs are easy to replace, at least in 10 bolts. (IMO)

    tRustyK5 has the answer. When I worked for Firestone, that is what I use to do whenever a customer couldn't find his/her key. It works perfectly.

    Just find a socket that is just a c-hair too small and pound it over the keyed lug. Then just unscrew it and It will come right out.

    Good luck

    You can also try a local tire shop............. they took my stripped ones off in 5 minutes...........all 4. Go with Gorilla locks for your next setup, the "keys" envelop the whole lock and won't allow stripping as easily.

    I've had good luck in the past with deep well impact sockets (prefably not your own), a BFH, and a ratchet.

    As a last resort, you could take the front hubs and rotors off with the wheel and drill out the studs form the back.

    A shop lost my key one time so they just tack welded nuts onto the locks. I was kind of glad they lost it because the new locks they bought me were much better than the old ones. I'm sure you already know this but, if you do weld them make sure you ground to the rim. I've seen too many people weld their bearings by grounding to the axle housing.

    I've had to do this a time or two....
    Take a die grinder and grind a slot on the end of the lock so it looks like a flathead screw. Then take one of those 1/2" sockets that has a big flathead bit in it and unscrew it.

    I was able to remove a set of wheel locks with a pipe wrench. It might be worth a try.
