It is possible for a locksmith to create a new key from a lock, and there are several ways to go about this depending on your situation. If you know the ‘pinning’ of the lock you need a key for then your locksmith will be able to cut you a key ‘to code’. However, your lock has a removable cylinder, another option a locksmith may take is to remove it and cut a new key directly from the pins. In the event that other methods haven’t worked, a locksmith can produce a new key by a technique called ‘impressioning’. In the case that you need a new key for your car, a specialised auto-locksmith will be able to cut you a new key and, if necessary, program it for your use.
