Ok here is the deal. I went to remove my draw bar the other day and my key broke off in the lock completely flush with the lock. And before anyone says I should have lubricated the lock I did, 3x's in 2 days before even attempting to turn the key. So anyway, I am looking for advice on cutting the lock off or the pin. Doesn't matter which as I am going to replace the entire set up anyway. The lock is a "dead bolt" style like http://www.etrailer.com/Locks/DeadBolt/40107.html but the pin itself look like a standard hitch pin with the curve on the other end. What would be better. Use a grinder with a cut off wheel or take it to a welding shop and have them use a torch to cut it off, or what?
