Query: Nice solid locks, but...

I bought these locks to use on my fence gates because they were supposed to be good for outdoor use. The rubber cover over the keyhole sounded like a good idea, but all they do is hold the moisture in so the mechanism rusts. After awhile, I had lots of trouble unlocking them; now I can't lock them any more. In fact, I can't even get the key out of the last one. I have since replaced them with locks that don't hold the water inside.
