Do you only have one key to something? Car? House? Boat?
Have you ever thought “what would happen if I lost this key?”
Let me tell you now, the price of copying a key, even an expensive key, is much lower than the cost (and headache) of losing the only one you have. Call your locksmith and have a few extras made before its too late. for some keys its a low a 3 dollars a copy, compared to the $150-$200 it would cost for a locksmith to come out to you and generate a new key when all yours are lost.
