Might be that lock needs to be replaced. But I would try some other oils or lubricants before doing that. Try something like white lithium grease or powdered graphite. Plus there are products (Locktite I think is one of them).
Is it cold where you are now? It might be only frozen water in there and for that you can heat the key with a butane lighter and then insert it to melt the ice.
