[AstroDiver]

I finally got to take my boat out Sunday on the lake. Last time was in the FL Keys back in late November. I had washed down the boat pretty good when we got back in November. [motor too intenally]
Well, I discovered that the locks on the front storage/fish bins have some corrosion. One, the key will not go all the way in and the other one is a little stiff.
What can I do to fix this situation? The locks were replaced under warranty almost three years ago because they were beyond working from the salt. I sprayed them with ARC corrosion preventative stuff yesterday.
Thanks for any help.
