Ring to Girlfriend Riddle
A King wants to send the diamond ring to his girlfriend securely. He got multiple locks and their corresponding keys. His girlfriend does not have any keys to these locks and if he sends the key without a lock, the key can be copied in the way. How can King send the ring to his girlfriend securely? 
King sent locked box with ring
King sent the key in another box
How will the girlfriend open the second box (that contains the key to the first box) if she doesn’t already have its key?
Did I said said lock the second box.let the key get copied
If the key is stolen (copied), what’s the safety of the lock? If that doesn’t matter, then the puzzle itself loses sense.
It can be copied only there is no risk of not reaching the girlfriend as per puzzle
In that case, there is nothing “puzzling” in the question. The statement that the key can be copied is irrelevant. The King can send the key anyway, irrespective of whether it can be copied or otherwise.
The king cannot send the key with the ring
That’s right, but it’s just common sense. No sensible person would send a locked box and its key together. There’s nothing ‘puzzling’ in it.
