Jimmying a lock refers to the act of forcing something open, such as a lock, door, or window, typically using a metal bar or a similar tool. It is a method of forced entry that bypasses the traditional locking mechanism.
Understanding the Term "Jimmying"
The term "jimmying" (also seen as "jemmying" in British English) specifically describes the use of leverage to pry open an object that is secured. When someone jimmies a lock, they are not picking the lock but rather using brute force to overcome its resistance. This often results in visible damage to the lock, doorframe, or window frame.
The action can be described using various forms of the word:
- Jimmying: The ongoing act of forcing something open.
- Jimmied: Describes something that has been forced open using this method (e.g., "The window was jimmied open.").
- Jimmies: Can refer to the tools used for this purpose, specifically small pry bars.
Tools and Targets of Jimmying
While a "jimmy" can refer to a specific type of crowbar, the act of jimmying can be accomplished with a range of tools designed for leverage.
| Common Tools Used | Common Targets |
|---|---|
| Crowbars | Doors (residential, commercial) |
| Pry bars | Windows (sliding, casement) |
| Large screwdrivers | Gates |
| Metal pipes | Less secure locks or latches |
| Spoons or other sturdy objects (for smaller tasks) | Sheds, toolboxes, certain vehicles |
The Process and Impact
The process of jimmying involves inserting the tool into a gap, such as between a door and its frame, or a window sash and its frame, and then applying force to pry it apart. This force can bend metal, splinter wood, or break latches, hinges, or locking mechanisms. Unlike lock picking, which aims to manipulate the internal components of a lock without damage, jimmying is inherently destructive.
- Security Implications: Jimmying is a common method employed by burglars and intruders due to its effectiveness in quickly gaining access. It is often a clear sign of a forced entry attempt.
- Preventative Measures: Strengthening doorframes, using robust locks (like deadbolts), installing anti-pry plates, and reinforcing window frames can help deter or prevent jimmying.
The act of jimmying highlights the importance of physical security measures beyond just the lock itself, extending to the integrity of the surrounding structure.
