Sticky door lock

When I bought my car it had rained recently and my drivers side lock was a little notchy. For the last couple of weeks I noticed it had gone away...Til it rained real hard a couple of days ago. Is there something I can spray in there? Or can I disassemle, lube and reseal or something like that?

Thanks

If something can't be fixed with WD40, a big rubber mallet, or duct tape, it can't be fixed, so replace it. In this case I'd try the former first.
