I've got a padlock that's been outside too long. The key won't turn
(although after copious amounts of WD40 it does, finally, enter the
lock) and it's in a rather hard to reach spot. I'm heading off to
Harbor Freight this weekend, so I was thinking that the best way to
remove the lock would be to buy an angle grinder and the appropriate
cutoff wheels.



An ordinary hacksaw or Dremel will do just fine, althought it may
take you a few minutes to cut through the hasp. I've cut through
a few with my Dremel and the heavy-duty (gray cap) wheels.


Next time buy a weatherproof padlock.

There are a LOT of (good) padlocks out there that will just take the
teeth off a hacksaw - but a good cutoff wheel on a 4" angle grinder
will take them off. (some might take the better part of a wheel
though)
