Removing Krytonite Lock

Hi folks,
About three years ago I bought a Kryptonite padlock to secure my kicker on my old OMC bracket. It was a replacement for an old Masterlock that was getting pretty rusty. This past weekend I was going to remove the motor to refinish the plywood motor pad on the bracket. The key would turn but the lock wouldn't open. At first I thought this might be self inflicted since when I installed the lock I sprayed in with OMC proctective goop that dries to a hard grease, so I thought the lock was just gummed up with grudge and such. I soaked it for a day in a small plastic bag full of Liquid Wrench with no luck.
A little web sleuthing suggests that the failure rate on these padlocks is pretty high. I Emailed Kryptonite but have yet to get a response. The guys down at my local hardware store think I shold go at it with a carbide hacksaw blade, which doesn't sound like too much fun. Any other ideas?
Thanks!

Mike

I've cut really large pieces of metal in tight places with a cutoff wheel
on a Dremel, or the flexible wand Dremel attachment. It can take a
little while, but it's easy work.

If the key turns all the way, try smacking the sucker with a hammer while the key is turned. Hold the key fully turned to the unlock position and tap the body of the lock down and away from the loop. That oughta do 'er.

If Mike's Persuasive Manipulation doesn't open it's little heart, I'd go at it with a "big" 2 1/2" cutoff wheel mounted on a pneumatic die grinder or on a specifically designed cutoff tool and about 90 psi of air.

Cover the gas tank, the sparks will be spectacular !!!

Don't let the hot pieces fall and burn anything!

Should take 5-10 seconds at the most.

Nuttin' like hot buttered hardened steel sprayed all over the workshop!

Success!!
Gee is it just me or are there lots of Mikes out there (sorry Joe). I don't have a Dremel so I had to go to plan B. Tried whacking it with the key turned and no luck. So I went at it with carbide hacksaw blade. It was a spirited energetic fight, but I finally won. When I'd cut most of the way throught one side of the loop, I thought it's a fifty-fity chance that I picked the one that turns, and luckily I did!
There's a moral in here somewhere. I futzed around with the thing for two days when If I'd just gotten after it I would have had it done in fifteen minutes. Thanks for the suggestions!

The old lock still works!
