Before I even knew any better, I took mine off like
that.  CP gun with about 550 ft. lbs. "true" torque. 
It was off in about 2 seconds.  I believe you could
damage the key or keyway, but probably could by hand
as well.  Phil is right about needing to lock the
crank to reinstall it correctly though.  I cheated by
using Loctite blue and the gun to reinstall.  I'm NOT
recommending this and will probably do it correctly
next time.  BTW, you can gauge torque surprising
accurately with a gun when you become very used to the
sound and frequency of the blows.  The "cadence" if
you will.  This assumes you use a quality gun at a
constant air pressure, and have a good torque wrench
to verify the values occasionally.  This will
establish your reference and "gauge" your ear
occasionally.  Again, I'm NOT advocating this, I just
believe it is possible.
