Duplicating a key from a lock is a common practice. A locksmith can provide you with a duplicate of the keys, even if you don't have the original. To make another duplicate of the key, you'll need a blank key that fits the profile of the lock you have. Without that blank space, your efforts are futile.
Keys are usually made of brass or a nickel-brass mixture, and the pins in a lock are also made of brass. Key duplicating machines are automated self-service kiosks that don't require interaction with a locksmith or employee. The key duplicator is then turned on and, as the original key and the empty key move horizontally through the machine, the blade cuts the blank key, using the original as a kind of template. If you try to use an empty lock of the wrong type and brand, the key will most likely not even enter through the keyhole. Maybe you collect old skeleton keys or live in an old house with interior locks that still use skeleton keys. For the price you'd pay if a locksmith went out and changed the key to your locks, you could buy yourself some shiny new knobs.
Security keys: All types of unique safe keys can be duplicated and may take longer, depending on the type of key. If you choose to mold the faucet with a procedure such as waxing, you will limit yourself to using metals with a relatively low melting point, such as bronze or copper, which, unless hardened with a hardened housing or galvanized chrome plating, are relatively soft and easily deformed.
