Destructive Entry

Destructive entry is a method of entry characterized by damage to or destruction of a lock, safe, or surrounding objects, such as a door, window, or wall. It is the primary method of entry in the majority of criminal cases involving the compromise of physical security, and is commonly employed by law enforcement personnel for rapid entry to a residence or facility. Locksmiths make use of destructive entry to compromise, service, and remove high-security locks and safes.

Destructive entry is contrasted with various forms of covert and surreptitious entry because of easily identifiable evidence of a compromise attempt or success. Many destructive techniques leave the lock or safe non-functional or otherwise impaired. In many cases repair or replacement of damaged components is attempted to hide evidence of entry.

Methods of Destructive Entry

Destructive entry can take many forms, some of which are extremely dangerous to the user, others in the vicinity, and forensic investigators or law enforcement personnel. The choice of method depends on the personal preference, skill level, tools, time allowed for entry, and financial resources of the user.

At heart, all methods use energy or force in a directed manner to displace, damage, destroy, or weaken components. In most cases, security is greatly reduced once components lose structural or molecular integrity.

Chemicals
Use of chemicals to affect the molecular structure of components. Chemicals, namely acids, to corrode, disintegrate, or dissolve components. Like temperature, chemicals often leave components vulnerable to other attacks.
Compression
Use of pressure against a component in complementary directions. Essentially, the opposite of tension. Causes distortion, compaction, or breakage of components. Compression is most often used to reduce the strength of materials so that other methods can be used.
Impact
Use of pressure and shock against a component. Striking and explosives are most common. Impact has a wide variety of results, including fracturing, breakage, deformation, and compression. Some methods of bypass use impact to retract the locking bolt, most of which are destructive. Explosives are one of the most dangerous methods of destructive entry, and use has dwindled with time as safer alternatives, such as drilling, have become popular.
Shearing
Use of pressure on a component placed betweeeen two edges. Cutting, chopping, and drilling are included in this category. Drilling is the most popular method of destructive safecracking and removal of locks by a locksmith.
Temperature
Use of extreme temperature to affect the molecular structure of components. High temperatures can vaporize, burn, melt, or re-temper components. Re-tempering can leave components soft or brittle, thus vulnerable to many other attacks. Low temperatures are less common, but can be used for similar purposes.
Tension
Use of pressure on a component in opposite directions. Stretching, pulling, prying, bending, or ripping are included in this category.
Torsion
Use of rotational pressure (torque) on a component. Twisting and torque and included in this category. Causes shearing, compression, and deformation of components.
