Sticking door locks? Solved!

So I was having SEVERE issues with doors not wanting to open, handles not working correctly and so on. I got the answers to our prayers, for some reason just spraying the whole assembly with Aerokroil fixed everything. I seriously was getting ready to replace the door assembly's for some serious cash. Hopefully this will save somebody else from making a mistake like I was going to! 
It probably seems like common sense for most people but I guess I'm not most people
