Skeleton keys are notorious for their use in movies and television shows, but they can also be found in real life. These keys are often used to open old doors or locks that have been lost. Picking a skeleton key lock can be a challenging task, but it is possible with the right tools and techniques. In this article, we will provide you with a step-by-step guide on how to pick a skeleton key lock.
To begin, you will need to gather the necessary tools. These include a tension wrench, a pick, and a key blank. The tension wrench is used to apply pressure to the lock, while the pick is used to manipulate the pins inside the lock. The key blank is used to create a new key that will open the lock. Once you have gathered your tools, you can begin the picking process.
The first step is to insert the tension wrench into the bottom of the keyhole. Next, insert the pick into the top of the keyhole and begin to gently manipulate the pins. The goal is to lift the pins high enough so that the key blank can be inserted into the lock. Once the key blank is inserted, turn it to open the lock.
The Anatomy of a Skeleton Key Lock
Skeleton key locks, also known as ward locks, have been around for centuries and are still commonly found in historic buildings, antique furniture, and safes. While they may appear complex, understanding their anatomy is crucial for successful lock picking.
Key Components:
Keyway: The keyhole, where the key is inserted, is surrounded by a metal plate or ward. Wards protrude into the keyway, preventing the insertion of non-specific keys.
Springs: Located within the lock, springs apply pressure on the tumblers, holding them in place until the correct key is inserted.
Tumblers: These are small, L-shaped pins that interact with the key’s serrations. When the key is inserted, the serrations align with the tumblers, allowing them to rotate and release the locking mechanism.
Pins: Small cylindrical pins rest on top of the tumblers, further obstructing the key’s path. The correct key aligns the pins and releases the tumblers.
Shear Line: This is the point where the tumblers interact with the pins. When the shear line is broken, the tumblers rotate and the lock opens.
Plug: The core of the lock that contains the keyway, tumblers, and other components. It rotates when the correct key is inserted.
Bitting: The pattern of serrations on the key that corresponds to the tumblers in the lock. Each unique key has its own specific bitting.
Understanding the Key Mechanism
Skeleton keys, also known as passkeys or master keys, are designed to open multiple locks, each with a unique keyway. This versatility is achieved by a unique key mechanism that lacks the wards or pins found in traditional locks.
The skeleton key features a long, flat blade with a series of notches cut along its edges. These notches correspond to the specific pins or levers within the lock cylinders. When the key is inserted, it aligns with the keyway, allowing the bitting on the key to interact with the internal mechanism.
Types of Key Bitting
The bitting patterns on skeleton keys vary depending on the lock type they are designed to open. Common bitting patterns include:
| Bitting Pattern | Description |
|---|---|
| Single-sided | Notches cut on one side of the blade only |
| Double-sided | Notches cut on both sides of the blade |
| Wavy | Notches cut in a sinusoidal pattern |
Identifying the Optimal Material
The material of a skeleton key lock is a critical factor in determining its security and durability. Here are the key considerations for choosing the right material:
Strength and Durability: The material should be strong enough to resist physical attacks, such as prying or smashing. Metals like steel and brass are typically the most robust. However, harder metals are more difficult to manipulate and cut.
Corrosion Resistance: If the lock will be exposed to moisture or outdoor elements, it’s crucial to select a corrosion-resistant material. Stainless steel and aluminum alloys are excellent choices in such conditions.
Machinability: The material should be easy to work with during manufacturing. This includes cutting, shaping, and creating the intricate mechanisms within the lock. Brass and zinc alloys offer a good balance between strength and machinability.
| Material | Strength | Durability | Corrosion Resistance | Machinability |
|---|---|---|---|---|
| Steel | High | High | Moderate | Low |
| Stainless Steel | High | High | Excellent | Moderate |
| Brass | Moderate | Good | Good | Excellent |
| Zinc Alloys | Good | Fair | Good | Excellent |
| Aluminum Alloys | Low | Fair | Excellent | Good |
Assessing Lock Strength and Security
When assessing lock strength and security, consider the following factors:
1. Materials and Construction:
High-quality locks are crafted from durable materials like brass, stainless steel, or case-hardened steel. They should have solid construction with no weak points or gaps in the housing.
2. Number of Pins:
The more pins a lock has, the harder it is to pick. Five or more well-crafted pins significantly increase the time and skill required for successful picking.
3. Pin Design:
Pin shapes and cuts can vary, making them harder to manipulate with a skeleton key. Security pins, such as mushroom, spool, or serrated pins, add an extra layer of protection.
4. Keyway Complexity:
The keyway, or opening in the lock where the key is inserted, plays a crucial role in security. Narrow, complex keyways, with multiple wards and ridges, make it more difficult to insert and manipulate a skeleton key. Additionally, keyways protected by rotating inserts or other mechanisms enhance resistance to unauthorized key insertion.
| Keyway Feature | Security Impact |
|---|---|
| Narrow and deep | Impedes skeleton key insertion |
| Multiple wards and ridges | Obstructs key manipulation |
| Rotating inserts or guards | Prevents unauthorized key entry |
Determining the Correct Size and Shape
Selecting the right size and shape of skeleton key is crucial for successful lock picking. Follow these guidelines:
Key Size
Skeleton keys come in a range of sizes, denoted by numbers. The number corresponds to the overall length of the key. Choose a key that is approximately the same length as the lock cylinder you intend to pick. A key that is too short may not reach the pins, while one that is too long may get stuck or damage the lock.
Key Shape
Skeleton keys have different shapes to accommodate various lock designs. They are typically categorized as follows:
| Key Shape | Lock Type |
|---|---|
| Single-sided | Locks with a single row of pins |
| Double-sided | Locks with two rows of pins |
| Warded | Locks with internal obstructions or wards |
| Bitted | Locks with key pins that are cut to specific depths |
| Wrench | Locks with a single large pin |
Determine the lock type and choose the appropriate key shape. If you are unsure, it’s safest to opt for a double-sided or warded key, as they are compatible with most common lock designs.
Inspecting the Keyhole for Clues
Carefully examine the keyhole for any irregularities or abnormalities. Look for:
1. Shape and Size:
Observe the keyhole’s shape and size. Skeleton keys come in various sizes and shapes, so matching the key’s width and depth to the keyhole is crucial.
2. Key Pins:
Sometimes, small pins or obstructions within the keyhole can interfere with the key’s insertion or prevent it from turning smoothly. If you encounter any resistance, check for any visible obstructions.
3. Obstructions:
Inspect the keyhole for any foreign objects, such as dirt, debris, or broken key parts, that may block the key’s entry.
4. Corrosion or Damage:
If the keyhole appears corroded or damaged, it may require cleaning or repair before attempting to insert the key.
5. Keyway Orientation:
Certain skeleton keys have a specific orientation or direction that they must be inserted into the keyhole. Check for any markings or grooves that indicate the correct orientation.
6. Keyhole Depth and Alignment:
The depth and alignment of the keyhole are also crucial factors to consider. Use a flashlight to illuminate the keyhole and check if the key can be inserted to its full depth. Misalignment between the key and keyhole can hinder successful lock picking.
