I have seen the term "hacking" been used to describe using a device via its interface, as intended..
Starting my car with a key is not hacking, starting my neighbors car with his key is neither. Obtaining the key without consent, might be. But that again could in fact be social engineering.
In comparison, using another (master)key that happens to fit would be akin to "cracking". If one engineered the key himself, thàt (along with the required investigative research work) might be hacking.
