This term typically refers to any lock that uses patented or unconventional design features to thwart the most common types of attacks on locks--picking and drilling. There are high-security cabinet locks, door locks, and padlocks. Even some cars are equipped with special high-security lock systems which are especially resistant to vandalism and conventional means of fitting a key. Some, but not all high-security locks also come with restricted keys. Professional locksmiths are the best source for high-security locking devices.
