Disc-detainer locks are known for their high security and complex internal mechanisms, often used in high-end security applications. As a supplier of Open Lockout Kits, I'm frequently asked about how these kits work on disc-detainer locks. In this blog, I'll delve into the science behind it, explaining the principles and processes involved.
Understanding Disc - Detainer Locks
Before we discuss how an Open Lockout Kit works, it's essential to understand the basics of disc - detainer locks. Unlike traditional pin - tumbler locks, disc - detainer locks use rotating discs instead of pins. Each disc has a notch of a specific size and position. When the correct key is inserted, the notches on the discs align, allowing the plug to rotate and unlock the lock.
The complexity of disc - detainer locks lies in the fact that the discs are arranged in a stack, and each disc must be precisely aligned for the lock to open. This makes them highly resistant to picking and other forms of unauthorized entry.
Components of an Open Lockout Kit
An Open Lockout Kit typically consists of several tools designed to manipulate the lock components. These may include tension wrenches, picks of various shapes and sizes, and sometimes additional tools for specific lock types. The goal of these tools is to mimic the action of the correct key and align the discs to unlock the lock.
How the Kit Works on Disc - Detainer Locks
Step 1: Applying Tension
The first step in using an Open Lockout Kit on a disc - detainer lock is to apply tension to the lock plug. A tension wrench is inserted into the keyway and turned gently in the direction that the lock would normally turn to unlock. This tension creates a binding force on the discs, making it easier to identify the correct position for each notch.
Step 2: Picking the Discs
Once tension is applied, the pick is used to manipulate the discs one by one. The pick is inserted into the keyway and used to rotate each disc until the notch aligns with the shear line. The shear line is the boundary between the stationary part of the lock (the shell) and the rotating part (the plug). When the notch of a disc aligns with the shear line, the disc is said to be "set."
This process requires a high level of skill and patience. The locksmith must feel for the slight click or movement that indicates the disc has been set correctly. Different discs may require different amounts of force to rotate, depending on their position in the stack and the design of the lock.
Step 3: Confirming Alignment
As each disc is set, the locksmith must confirm that it remains in the correct position. This is done by maintaining the tension on the plug and carefully checking that the disc does not rotate back out of alignment. If a disc moves out of position, the process must be repeated for that disc.
Step 4: Unlocking the Lock
Once all the discs have been set and confirmed to be in the correct position, the tension on the plug can be increased slightly. If all the discs are aligned correctly, the plug will rotate, and the lock will unlock. This final step requires a delicate balance of force to avoid disturbing the alignment of the discs.
Advantages of Using an Open Lockout Kit
Using an Open Lockout Kit on disc - detainer locks offers several advantages. Firstly, it provides a non - destructive way to open the lock. This is important in situations where the lock needs to be reused or where damage to the lock is not an option. Secondly, it allows for quick access in emergency situations, such as when a key is lost or stolen.
