Well, it could be for the fact that keyholes are small and dark and it is pretty tough to see what is going on inside of them. It can also be because it is one of the most complicated parts of a broken lock.
It is important to figure out if something is blocking your keyway, so you should insert your key and try to move it to the shoulder of your key. If you find that something is blocking the keyway, you can try to get it out but it might just be that the lock needs to be replaced. If nothing is blocking the keyway but it still doesn’t work, chances are the lock or the key is worn out and you need to replace it.
