I have seemed to have lost my keys to my hitch receiver lock. The lock is similar to this:
All I know what to do is to either try and cut it which i do not is possible,
grind the opposite end from the lock, which again I think will not work,
try to beat the key end to death with a heavy hammer and even though I have done that with heavy hammers on typical padlocks before, I do not think it will work on this setup,
and finally, talk to a friend with a cutting torch to see if torch cutting is doable.
Does anyone habe sucessful experience with this problem?
