Thanks so far for the help. Here's a little more detail: Yes, it is
the kind that wraps all around the receiver and has a little mushroom
shaped thing that goes inside where the hitch ball normally does. The
lock body is about 1/4 inch steel that wraps all around (in kind of a
U shape) the part of the trailer that holds the ball. The key inserts
and turns very freely, but I can feel the locking mechanism budge or
move even a fraction.

I've been soaking it in WD 40 all day and periodically whacking it
with a hammer. I've also been trying to pry on the mushroom thingy
whenever I can. Since the lock is on a trailer and a boat is on the
trailer, I cant do much but work on it in position. I'll keep up my
technique until it either gets free or Monday comes and I relent and
call a locksmith.

Keep the ideas coming!

Put the WD40 away and get the stuff Tom told you to get. Seriously.

The dude knows of which he speaks.

Once you've tried that, and if it still doesn't work, come back.

Ah - that's a simple lever mechanism with a spring.

You really need to use PB Blaster because the levers are probably
rusted to the housing.

Get a grinder and a metal cutting wheel. It will be off in 45 seconds.
The locksmith will cost about the same and, in this case, you still
have a new tool.

Harbor Freight has cheap little angle grinders for $15-20 that would
probably make short work of it.

Yes! That is exactly what I am dealing with. Quite a secure device, if
I may say so. I'll try to find some pb blaster.
