Inside the barrel of the lock are several small "cylinders". When you push
the key in, these are pushed upwards by an amount proportional to the
corrugation in the key. If the lock gets contaminated, the cylinders, which
are spring loaded, may stick and not slide into the correct position. The
key can only be turned when all these cylinders are in the correct
position. That's the best explanation I can give.
The solution is to soak the lock in WD40 or Plus Gas -- and pray. You could
also apply a little gentle heat (or, better, heat the key) and work the key
backwards and forwards until things become unstuck.
If you attempt to turn the key by force, you will only make matters worse
and could break the key.
