If you find yourself in a situation where you need to cut through an Onguard lock, you’re not alone. These locks are known for their durability, but they’re not impenetrable. With the right tools and techniques, you can cut through an Onguard lock without damaging the bike or the lock itself.
The first step is to gather your tools. You’ll need a rotary tool with a cutting blade, a pair of safety glasses, and a pair of gloves. Once you have your tools, you’re ready to begin. Start by securing the Onguard lock in a vice or on a workbench. This will help to keep the lock from moving while you’re cutting. Next, put on your safety glasses and gloves.
Now, you’re ready to start cutting. Hold the rotary tool in one hand and the cutting blade in the other. Start by making a small cut in the shackle of the lock. Once you have a small cut, you can start to widen the cut until the shackle is completely severed. Be careful not to cut into the bike or the lock itself. Once the shackle is severed, the lock will be open.

Gathering Necessary Tools
The first step in cutting an Onguard lock is to gather the necessary tools. These include:
- A rotary tool
- A cutting wheel
- A safety guard
- A pair of safety glasses
- A pair of gloves
Equipment Selection and Setup
**Rotary Tool:** Choose a rotary tool with variable speed settings and sufficient power to cut through the lock shackle. A higher speed will result in a faster cut, but it is important to avoid excessive speed, which can overheat the cutting wheel and damage the tool.
Cutting Wheel: Select a cutting wheel appropriate for the material of the lock shackle. For steel shackles, a diamond-coated cutting wheel is ideal. For hardened steel shackles, a carbide-grit cutting wheel is necessary.
Safety Guard: Install the safety guard on the rotary tool to protect your hands from flying debris during cutting. Make sure the guard is securely attached and covers the cutting wheel adequately.
Preparing for Cutting
**Safety Gear:** Wear safety glasses and gloves to protect yourself from sparks and debris. Ensure the glasses provide adequate eye protection, and the gloves offer sufficient grip and heat resistance.
Secure Lock: Place the lock in a stable position using a vise or clamp. Adjust the position to provide clear access to the shackle without obstructing the cutting wheel’s path.
Identifying the Lock Mechanism
Identifying the lock mechanism of an Onguard lock rotary tool is crucial for understanding how to cut it effectively. This unique lock design incorporates several key components that work together to prevent unauthorized access:
1. Shackle:
The shackle is the U-shaped metal bar that secures the lock to the bike frame. It is made of hardened steel, making it difficult to cut.
2. Retainer:
The retainer is a cylindrical housing that holds the shackle in place. It is made of a strong metal alloy that is resistant to drilling and hammering.
3. Locking Mechanism:
The locking mechanism is the core of the Onguard lock rotary tool and is highly sophisticated. It consists of the following components:
- Key pins: These pins are arranged in a specific pattern and must be lifted by the key to unlock the lock.
- Driver pins: These pins are pushed down by the key and engage with the key pins to create a unique combination.
- Shear line: This is a thin line where the driver pins and key pins meet. If the key is incorrect or forced, the driver pins will shear off, rendering the lock unusable.
| Component | Description |
|---|---|
| Shackle | Hardened steel U-shaped bar that secures the lock to the bike frame |
| Retainer | Strong metal alloy housing that holds the shackle in place |
| Locking Mechanism | Core of the lock, consisting of key pins, driver pins, and a shear line |
Cutting the Shackle
If you’re working with a small shackle, you should be able to cut through it using a pair of bolt cutters. If the shackle is too thick, you may need to use a hacksaw. To cut through the shackle:
- Secure the lock in a vise.
- Position the bolt cutters or hacksaw at the base of the shackle.
- Apply firm, steady pressure as you cut through the shackle.
- Once the shackle is cut, remove the lock from the vise.
Here are some additional tips for cutting the shackle:
