Most high security locks use certain designs or characteristics that improve their ability to resist manipulation and forced entry for a given amount of time.

The main goal of all high security locks is to  instead to make defeat too expensive or time consuming to be feasible.

All high-security locks use strong materials and designs that make them resistant to destructive entry techniques. Steel rods, ball bearings, and hardened materials are common.

Most high security locks have key bows and warding patterns that are patent protected to prevent unauthorized manufacturing. Keys to high security locks also generally require a security card be presented for a locksmith to duplicate keys.
