High security locks are crafted with locking mechanisms that can only be operated by a single key. This makes them almost impossible to pick, and make bump keys (a favorite tool of would-be burglars) useless. Another way high security locks offer more protection is that some of them cannot have keys duplicated without your authorization. This ensures that you are the only one who is able to say when a key is made and who that key goes to. Specialty features also are included, like steel door frames and bolts that prevent common methods of forced entry including prying and sawing.
