Rusty Keyhole

So it takes you fifteen minutes to reach your home and almost half an hour to enter your house because of that rusty keyhole that just doesn’t cooperate. Instead of going through the entire trouble of finding a repair shop to find a repairman and then wasting hours overseeing the person work you can simply do away with this problem by applying WD-40 on it. You can do the same if you have got a rusty key.
